New mpox strain confirmed in US state for first time

13 February 2025 at 15:28

The New York State Department of Health issued a health advisory Wednesday about the emergence of a new strain of mpox (formerly monkeypox).

The first case of mpox clade Ib in New York State was confirmed in a symptomatic individual who had recently traveled from Africa.

The present risk to the public remains low, the department noted, and there are no additional known community cases of this strain in New York State currently.

IS MPOX THE NEXT COVID? INFECTIOUS DISEASE EXPERTS ADDRESS PANDEMIC POTENTIAL

State Health Commissioner Dr. James McDonald shared that the infected individual is under the care of a physician and isolated "until the full resolution of symptoms."

"There is no known local transmission of mpox clade Ib in the community where the individual lives or anywhere within New York State," he said in a statement.

McDonald added that the JYNNEOS vaccine, which is a two-dose preventative vaccine series for mpox, is "expected to be effective" against this new strain.

"[It is] available for individuals at risk with the standing order I signed last year," he noted. "There is no immediate risk to the general public."

The health department added in its advisory that individuals should inquire with their local pharmacy or healthcare provider about vaccine availability as they continue to "monitor and maintain the situation."

Mpox is "rarely fatal," according to the department, but can be dangerous for people with immunocompromising conditions, as well as older adults, young children and pregnant women.

Symptoms can include rashes that progress to "painful skin lesions," in addition to swollen lymph nodes, fever, sore throat, headaches, back pain, low energy and muscle aches, the department listed.

There is a "high likelihood of transmission" until these lesions scab over, which means infected individuals are encouraged to isolate until new skin forms at the lesion site.

Mpox can spread through close, intimate contact with sores, scabs or rashes, the department stated, as well as through the respiratory droplets, saliva or mucus of an infected person.

Those who plan to travel to areas with reported cases of mpox should consider being vaccinated with the two doses of JYNNEOS, experts recommend.

Dr. Myles Druckman, global medical director at International SOS in California, told Fox News Digital that there have been reports of this strain in several countries in Central and Eastern Africa.

"We’re finding that other countries have also reported travel-associated cases of clade I, including Belgium, Canada, China, France, Germany, India, Ireland, Oman, Pakistan, South Sudan, Sweden, Thailand, the United Kingdom and Zimbabwe," he noted.

"It's important to recognize that cases of this strain are expected due to the ongoing outbreak in multiple countries and the risks associated with global travel."

Mpox can be infectious for up to four days before symptoms occur, but it is most contagious from the time symptoms appear until about two to four weeks later, according to Druckman.

The expert emphasized that vaccination is recommended for high-risk individuals, such as healthcare workers with high exposure or people with weakened immune systems.

"Prevention of mpox is mainly through vaccination and avoiding skin-to-skin contact with others – especially those with symptoms or visible outbreaks – and observing good personal hygiene and washing hands well and frequently," he added.

New bird flu strain detected in Nevada dairy worker, CDC says

11 February 2025 at 14:54

A new type of bird flu has been detected in a human dairy worker in Nevada.

This strain is different from the version that’s been spreading in herds since last year, according to the Centers for Disease Control and Prevention (CDC). 

The case was apparently mild, as the Churchill County dairy worker was not hospitalized and has recovered, the Associated Press reported, citing health officials.

BIRD FLU UPTICK IN US HAS CDC ON ALERT FOR PANDEMIC 'RED FLAGS': REPORT

The person mainly experienced eye redness and irritation, similar to most bird flu cases associated with dairy cows, according to the AP.

While the new bird flu strain, D1.1, has been reported in more than a dozen humans exposed to infected poultry, this is the first cow-to-human case.

In a press release addressing the situation, the Central Nevada Health District (CNHD) confirmed there is no evidence of this virus being spread from the infected individual to other people.

BIRD FLU PATIENT HAD VIRUS MUTATIONS, SPARKING CONCERN ABOUT HUMAN SPREAD

The CDC noted on its website that bird flu’s risk to the general public remains low.

But those who are in constant and close contact with cows, poultry and other animals are at a higher risk — and are encouraged to wear protective equipment and take necessary precautions.

Jacob Glanville, CEO of Centivax in San Francisco, commented in a statement to Fox News Digital that within a week of the D1.1 strain being detected in Nevada cows, there was already a human infection.

"This isn’t the first D1.1 human infection: It has already resulted in an American death, a severe illness, and some other infections in five other states," the expert said.

"The significance of this new infection is to reveal how quickly we go from cattle infections to human spillover."

Glanville confirmed that the cattle infections of the D1.1 strain prove that it contains mammalian adaptive mutations.

"While we have yet to see human-to-human transmission, with such rapid progression from cattle to human cases, it may only be a matter of time before an H5N1 pandemic," he said.

MAHA, RFK Jr. confirmation put childhood vaccines in spotlight: MMR fact vs fiction

11 February 2025 at 03:30

Amid Robert F. Kennedy Jr.’s push to improve healthcare as part of the Make America Healthy Again (MAHA) movement, there is a growing focus on vaccine transparency.

One of the most common childhood inoculations — the measles, mumps and rubella (MMR) vaccine — has been a requirement for school attendance since its development in the 1970s.

Fox News medical contributor Dr. Nicole Saphier answered some frequently asked questions regarding the vaccine in a video for Fox News Digital. (See the video at the top of the article.)

MAKE AMERICA HEALTHY AGAIN: WHAT TO KNOW ABOUT THE MOVEMENT

People often ask why the three vaccines are combined, which Saphier said is simply for convenience.

"From a public health standpoint, if the goal is to vaccinate as many children as possible to reach that herd immunity and keep these infections at bay, again, parents are more likely to only bring their child to the pediatrician that one time," the doctor said.

"And on a child, isn't it easier to give one injection as opposed to three separate injections?"

LARA TRUMP ON FOOD, HEALTH AND AMERICA'S CHILDREN: 'WE WANT THE TRUTH'

Saphier also addressed concerns about MMR vaccine side effects, including inflammatory reactions at the site of the injection, where the skin can become red and warm.

Children can also have low-grade fevers and feel irritable or lethargic, which is "likely to happen" even with each individual vaccine – not just when the vaccines are combined.

"The reality is there are always side effects when it comes to any sort of healthcare intervention," she said in the video. "But with vaccines in particular, you can have the more mild side effects, and there are some severe, more rare side effects that are well-documented."

The potential for a link between autism and vaccinations has been a deterrent for many parents when choosing to vaccinate their children, but Saphier said the "overwhelming majority" of "good research" shows no causal link.

BILL GATES LIKELY HAD AUTISM AS A CHILD, HE REVEALS: ‘WASN’T WIDELY UNDERSTOOD’

One of the largest studies, conducted in Denmark, found a lower risk of autism in more than 650,000 vaccinated children, the doctor noted.

While the U.S. has a higher incidence of autism compared to other countries, specifically Europe, the doctor revealed that European nations have higher rates of MMR vaccine uptake.

"The signs and symptoms [of autism] start to show around the time we're giving all these vaccines, so it makes sense to kind of think they may be related," she said. 

"And it made sense to do as much research as we can to make sure there isn't a link."

MAHA MOMS CALL FOR 'RIGOROUS TRANSPARENCY' INTO HEALTH CONCERNS

"But I think we need to be looking really hard at our environment, what we're ingesting, the pollutants, the toxins, everything in big agriculture, big pharma, in our food industry and everything else."

Saphier suggested that a link to autism may be found after diving into the "harmful chemicals" consumed by Americans that other nations do not consume.

The doctor also said that medical agencies — such as the Centers for Disease Control and Prevention (CDC) and the American Academy of Pediatrics — should be "less stringent" on vaccination schedules, leaving the decision to the parents.

"If parents don't want to give these vaccines when their babies are so little, I think it's OK to have that conversation and let them wait until their child's a little bit older before they head off to kindergarten," said Saphier, who is a mother of three boys.

For more Health articles, visit www.foxnews.com/health

"Because maybe at that time, you start to see signs of autism between about 1 to 3 years of age for the most part. So maybe let the parent get their child through that time, and if there aren't signs of autism, then maybe they'll feel better about … being able to vaccinate their children."

"It should be a conversation between the doctor and the patient," she said.

"Unfortunately, during the COVID pandemic, the CDC and a lot of healthcare professionals really took away this conversation." 

"By putting the COVID vaccine and booster for children in the same basket as MMR and some of the other vaccines, when it comes to children, that was the biggest mistake they could have ever [made]," Saphier continued. 

"That has caused more vaccine hesitancy and concern."

Saphier expressed her hope that the MAHA movement will help identify safety signals in vaccines, which will "give parents the confidence they need to continue with the vaccine programs, because they really can save lives."

Some winter viruses could trigger heart complications, experts warn

1 February 2025 at 08:00

As health officials report a surge of winter viruses, health experts are warning that heart disease symptoms can sometimes mimic respiratory illnesses.

Four viruses are circulating in the U.S., sparking concerns of a possible "quademic."

Respiratory syncytial virus (RSV), influenza, COVID-19 and norovirus are all at "very high levels" around the country, experts warn. 

NEW BIRD FLU STRAIN DETECTED ON POULTRY FARM AS EXPERTS MONITOR MUTATIONS

The American Heart Association (AHA) confirmed that certain viruses have been linked to increased risk of heart attack and stroke

"The highest risk is within three days of infection, but remains heightened for up to 90 days," the AHA stated on its website.

Johanna Contreras, M.D., a cardiologist at Mount Sinai Fuster Heart Hospital in New York City, said she has seen people mistaking virus symptoms for serious heart complications.

Some patients who experience shortness of breath, wheezing, coughing, swelling and palpitations may assume their symptoms are linked to a cold when these could be signs of heart failure, she said in a release sent to Fox News Digital.

FEELING EXTRA TIRED? THIS VIRUS COULD BE THE CULPRIT, STUDY SUGGESTS

Weakness, fever, dizziness and chest pain could also mask potentially life-threatening conditions.

Those may include pulmonary embolism (blood clot in the lungs), heart attack, pericarditis (inflammation around the lining of the heart), heart failure or viral myocarditis (inflammation of the heart muscle), according to Mount Sinai cardiologists.

Viruses can provoke an inflammatory condition, which can lead to or worsen cardiac conditions, according to Dr. Icilma Fergus, director of cardiovascular disparities for the Mount Sinai Health System in New York City.

"Typically, those [viruses] that make one sicker and promote a hypercoaguable state (an increased tendency to form blood clots) are more dangerous," she told Fox News Digital. 

THIS DISEASE KILLS MORE PEOPLE THAN ALL CANCERS AND ACCIDENTS COMBINED

"The focus has now been increasingly placed on RSV and norovirus on top of the known influenza and COVID viruses."

Anuradha Lala, M.D., another cardiologist at Mount Sinai in New York City, noted that the body’s immune system creates an inflammatory response to fight and eliminate the virus — but this inflammation could inadvertently harm cardiac tissue. 

"If you have a known heart condition, viral infections can bring on exacerbations — or a worsening of the underlying tissue — whether it is atrial fibrillation, coronary heart disease or heart failure," she noted in the release.

A recent patient at the hospital recently experienced severe shortness of breath, weakness, palpitations and fatigue, fearing they had heart failure, she noted. 

"After they had bloodwork taken, there was a frantic moment when we could not reach the patient to share results that revealed a significantly elevated troponin level, which can be linked to a heart attack," she shared in the release. 

"Although we suspected the worst, we eventually reached the patient and they were hospitalized with influenza A and severe viral myocarditis. They were treated appropriately and luckily there was a good outcome."

DIABETES, HEART DISEASE CASES SKYROCKET — AND SCIENTISTS SUGGEST A KEY REASON

Older adults — as well as those who are immunocompromised or have a history of heart issues or other underlying conditions — are particularly at risk for cardiac complications, according to the Mount Sinai cardiologists. 

"Anyone is susceptible, even healthcare providers — and anyone who is not paying attention to their symptoms may get sick with potentially life-threatening complications," Fergus said in the report.

Patients who notice persistent chest pain and palpitations after a viral illness should consider ruling out myocarditis, which is inflammation of the heart muscle, according to Contreras.

It is important to discuss any post-virus symptoms with a healthcare professional, especially for those in high-risk groups, health experts told Fox News Digital.

Specific symptoms that warrant emergency attention include chest pain, difficulty breathing or staying awake, feelings of passing out, or extremes of blood pressure.

Swelling of the legs may also be linked to cardiac events — especially if there is also an underlying heart condition or risk factors such as obesity, diabetes or a family history of heart disease, Lala stated in the Mount Sinai release.

During the cold, damp winter months, certain viruses may thrive and become more virulent, Fergus told Fox News Digital. 

"People should stay vigilant and observe for symptoms of an impending cold," she advised. "Get tested to know what virus you have, as the antiviral treatments are different."

People should take measures to avoid exposure to winter illnesses and seek treatment if they become ill, especially if they have an underlying condition, Fergus advised.

It is recommended that those who are in vulnerable groups get vaccines when available, the cardiologist added.

The American Heart Association recommends following the below precautions to reduce the chances of contracting a virus:

Ebola outbreak reported in African country — here’s what you need to know

29 January 2025 at 17:47

An Ebola outbreak has been reported in the Democratic Republic of the Congo (DRC).

At least a dozen cases of the hemorrhagic fever have been reported in the Bolamba health zone, which is located in the Équateur Province in the DRC. Eight deaths have been reported.

Colomba Mampuya, president of the Red Cross/Ecuador committee, reportedly shared the information with media on Jan. 27.

CDC WARNS US PUBLIC HEALTH OFFICIALS OF EBOLA-LIKE DISEASE

Meanwhile, the neighboring country of Tanzania has been grappling with an outbreak of Marburg fever.

"This is an unusually high death rate, even for Ebola," said Jacob Glanville, CEO and president of biotechnology company Centivax in San Francisco.

"This suggests either that more active cases have been identified, or that this strain is more lethal than average for prior strains, or that medical care was unusually poor for these subjects," he told Fox News Digital. 

The cases were identified in isolated villages, which improves the odds of outbreak isolation and increases the chance that medical care was substandard, Glanville noted. 

"However, biopsy samples should immediately be sequenced to rule out a new and potentially more lethal form of Ebola," he said.

KANSAS CITY TUBERCULOSIS OUTBREAK IS LARGEST IN US HISTORY

Samuel Scarpino, director of AI and life sciences and professor of health sciences at Northeastern University in Boston, reiterated that the ongoing situation in rural DRC is "quite serious."

"While the risk of widespread transmission is likely low, local impacts could still be substantial," he told Fox News Digital. 

"It is essential that the international community provides medical and public health support to DRC and that vaccines be made quickly available in both the affected and surrounding areas."

Both experts agreed that the U.S. is not at risk.

"Because Ebola only spreads from symptomatic individuals, the risk that a traveler could spark a small cluster of cases outside of DRC is very low," Scarpino said.

"We will be watching the situation closely, but currently, the risk to the U.S. is incredibly low."

Ebola occurs when someone is infected with orthoebolavirus zairense, which is a virus mainly found in sub-Saharan Africa, according to the Centers for Disease Control and Prevention (CDC).

The virus was first discovered in 1976 in the DRC.

The resulting disease is life-threatening, causing death in up to 90% of cases.

Initial symptoms of Ebola disease include "dry" symptoms like fever, aches, pains and fatigue, the CDC stated.

As the disease progresses, the person may experience "wet" symptoms like diarrhea, vomiting and unexplained bleeding.

Symptoms usually begin within eight to 10 days of exposure, according to the same source.

The sickness is spread through contact with bodily fluids from someone who has been infected. 

In rare cases, it may spread from contact with an infected animal.

The best ways to prevent infection are to avoid contact with bodily fluids of infected people, to wear the proper protective equipment in high-risk environments, and to monitor for symptoms to ensure timely medical attention.

There are two FDA-approved medications (monoclonal antibodies) available to treat Ebola disease: mAb114 (Ansuvimab, also known as Ebanga) and REGN-EB3 (Inmazeb).

Patients should also receive supportive care, including fluids and electrolytes, medicine to treat symptoms and any necessary treatment for infections, according to the CDC.

One state leads country in human bird flu with nearly 40 confirmed cases

12 January 2025 at 16:55

A child in California is presumed to have H5N1 bird flu, according to the San Francisco Department of Public Health (SFDPH).

As of Dec. 23, there had been 36 confirmed human cases of bird flu in the state, according to the California Department of Public Health (CDPH).

This represents more than half of the human cases in the country.

LOUISIANA REPORTS FIRST BIRD FLU-RELATED HUMAN DEATH IN US

The latest pediatric patient, who lives in San Francisco, experienced fever and conjunctivitis (pink eye) as a result of the infection.

The unnamed patient was not hospitalized and has fully recovered, according to the SFDPH.

The child tested positive for bird flu at the SFDPH Public Health Laboratory. The U.S. Centers for Disease Control and Prevention (CDC) will perform additional tests to confirm the result.

It is not yet known how the child was exposed to the virus and an investigation is ongoing.

"I want to assure everyone in our city that the risk to the general public is low, and there is no current evidence that the virus can be transmitted between people," said Dr. Grant Colfax, director of health, in the press release. 

BIRD FLU PATIENT HAD VIRUS MUTATIONS, SPARKING CONCERN ABOUT HUMAN SPREAD

"We will continue to investigate this presumptive case, and I am urging all San Franciscans to avoid direct contact with sick or dead birds, especially wild birds and poultry. Also, please avoid unpasteurized dairy products." 

Samuel Scarpino, director of AI and life sciences and professor of health sciences at Northeastern University in Boston, is calling for "decisive action" to protect individuals who may be in contact with infected livestock and also to alert the public about the risks associated with wild birds and infected backyard flocks. 

"While I agree that the risk to the broader public remains low, we continue to see signs of escalating risk associated with this outbreak," he told Fox News Digital.

Experts have warned that the possibility of mutations in the virus could enable person-to-person transmission.

"While the H5N1 virus is currently thought to only transmit from animals to humans, multiple mutations that can enhance human-to-human transmission have been observed in the severely sick American," Dr. Jacob Glanville, CEO of Centivax, a San Francisco biotechnology company, told Fox News Digital.

"This highlights the requirement for vigilance and preparation in the event that additional mutations create a human-transmissible pandemic strain."

As of Jan. 10, there have been a total of 707 infected cattle in California, per reports from the California Department of Food and Agriculture (CDFA).

In the last 30 days alone, the virus has been confirmed in 84 dairy farms in the state.

‘Rabbit fever’ cases rising in US as CDC warns of zoonotic bacterial disease

10 January 2025 at 12:52

Cases of tularemia, also known as "rabbit fever," are on the rise in the U.S., according to a new report from the Centers for Disease Control and Prevention (CDC).

Caused by the bacteria Francisella tularensis, the disease commonly infects rabbits, hares and rodents. However, it is zoonotic, which means it can spread from animals to humans.

The bacteria is a "tier-1 select agent," a classification given to agents and toxins that "present the greatest risk of deliberate misuse with significant potential for mass casualties or devastating effects to the economy, critical infrastructure or public confidence, and pose a severe threat to public health and safety," per the CDC. 

SUPERBUGS DUE TO ANTIBIOTIC RESISTANCE COULD KILL 39 MILLION PEOPLE BY 2050, LARGE STUDY FINDS

Although tularemia is relatively rare, with only 2,462 diagnoses between 2011 and 2022, cases have risen 56% compared to the prior decade (2001 to 2010), as reported in the CDC’s Morbidity and Mortality Weekly Report.

"Increased reporting of probable cases might be associated with an actual increase in human infection, improved tularemia detection or both," the report states.

Daniel Ruderfer, M.D., chief of the Division of Pediatric Infectious Diseases at Hackensack Meridian K. Hovnanian Children's Hospital in New Jersey, believes that the increase in cases is mostly due to improved microbiology detection methods.

"The traditional method of confirming cases has historically been via growth in culture and antibody testing," he told Fox News Digital. 

"However, newer detection methods, such as PCR testing, are likely a major contributor to the increase in reported cases."

Humans can contract the disease through bites from deer flies or ticks, contact with infected animals, or exposure to contaminated water or aerosols, the same source stated.

Symptoms of tularemia can vary depending on the type of disease.

General symptoms include chills, headache, malaise, fatigue, anorexia, myalgia, chest discomfort, cough, severe sore throat, vomiting, diarrhea, and abdominal pain, according to Ruderfer.

"Depending on the location of the infected bit or scratch, people can develop localized lymphadenopathy (enlarged lymph nodes) and a cutaneous ulcer at the infection site," he said. 

"Other manifestations include conjuctivitis, pneumonia and potentially even bloodstream infections."

The death rate from the disease is typically low, less than 2%, but the CDC noted that it can be as high as 24% in rare, severe cases.

Tularemia can be treated with antibiotics, but no vaccine is currently available.

"The infection is absolutely dangerous and potentially life-threatening if not treated with appropriate antibiotics," said Ruderfer.

Those most at risk include children between 5 and 9 years of age, older men, American Indian and Alaskan Native people, and those living in central U.S. states, according to the report.

The general population is not at an "obvious" risk for infection unless they come into physical contact with an infected rabbit, tick or deer fly, the expert noted. 

Those who hunt or interact routinely with rabbits should see a doctor if they develop any concerning symptoms, he advised.

For more Health articles, visit www.foxnews.com/health

"Many factors might contribute to the higher risk for tularemia in this population, including the concentration of Native American reservations in central states and sociocultural or occupational activities that might increase contact with infected wildlife or arthropods," the CDC wrote.

Bird flu patient had virus mutations, sparking concern about human spread

30 December 2024 at 14:02

The patient in Louisiana who was hospitalized with severe bird flu illness was found to have a mutated version of the virus, the U.S. Centers for Disease Control and Prevention (CDC) announced last week.

The fact that the virus mutated within the patient suggests that it could potentially spread from human to human.

The CDC analyzed samples of the H5N1 virus that were collected from the patient, comparing its genomic sequences to those of infected dairy cows, wild birds, poultry and other animals, the agency stated.

BIRD FLU LEADS TO SEVERE HUMAN ILLNESS AND STATE OF EMERGENCY

"The analysis identified low frequency mutations in the hemagglutinin gene of a sample sequenced from the patient, which were not found in virus sequences from poultry samples collected on the patient’s property, suggesting the changes emerged in the patient after infection," the CDC said.

"While these low frequency changes are rare in humans, they have been reported in previous cases of A(H5N1) in other countries and most often during severe disease."

Based on the discovery of these genetic changes in the virus, health officials recommend performing "ongoing genomic surveillance" in people and animals, taking steps to contain bird flu outbreaks among dairy cattle and poultry, and taking steps to prevent transmission when exposed to infected animals or environments.

BIRD FLU CAUSES DEATHS OF CATS AND ZOO ANIMALS AS VIRUS SPREADS IN US

The CDC maintains that the risk to the general public is still low.

"The same mutations were not present in viral genomes sampled from the backyard birds that presumably infected the individual," Samuel Scarpino, director of AI and life sciences and professor of health sciences at Northeastern University in Boston, confirmed to Fox News Digital. 

"Because the mutations were present in the human patient, but not the backyard birds, this suggests that the mutations arose during the course of that individual’s infection."

Dr. Marc Siegel, clinical professor of medicine at NYU Langone Health and Fox News senior medical analyst, told Fox News Digital, shared his thoughts on the significance of this finding.

"It is somewhat concerning that the H5N1 bird flu virus found in the Louisiana patient showed a mutation that allowed it to enter the upper airways more easily in this patient, but this mutation has been seen before," he told Fox News Digital.

The good news, the doctor noted, is that there have not been any reports of the Louisiana patient transmitting the virus to other humans.

"We know the mutations to look out for in terms of the potential to spread among humans" based on previous research, Siegel said. 

"It is important that surveillance among domestic poultry and dairy cattle is extensive," he added. 

Scarpino agreed that while the mutations are "concerning," they "likely do not represent an increased risk to the public."

"Similar events — mutations arising during infection that increase risk in humans — occurred with the individual who was infected with H5N1 from wild birds in Canada and have happened a number of times during previous H5N1 outbreaks outside the U.S. and Canada," he told Fox News Digital. 

"To date, it does not appear as though the individual in Louisiana transmitted the infection to other people."

The doctor cautioned, however, that the more opportunities the virus has to infect people, the more likely similar mutations will occur and spark a "chain of transmission" in humans.

"Each human infection represents a spin of the epidemic roulette wheel," Scarpino said. 

"We need to take active steps to eliminate H5N1 infections in agricultural populations and better understand why so many wild birds continue to be infected."

Traveling for Christmas? Stay healthy with these 7 tips

22 December 2024 at 13:10

Travel is a big part of the holiday season, with statistics showing that more than 119 million Americans plan to embark on some type of journey between Christmas and New Year's.

Unfortunately, traveling also increases the risk of getting sick — but there are steps you can take to increase your chances of staying healthy while away from home.

"When you're traveling, when you're on the road, there's a lot of risk of stress and disorientation," Dr. Marc Siegel, clinical professor of medicine at NYU Langone Health and Fox News senior medical analyst, told Fox News Digital.

NEW TRAVEL TREND HAS AMERICANS CHASING FOUNTAIN OF YOUTH

"You're not in your usual habitat, and that can make people disoriented, upset, anxious or even sleep-deprived, especially when changing time zones."

Siegel shared some of his top tips for preventing illness during holiday travel.

Staying hydrated has been shown to boost the immune system and protect against illness.

Water is always best, but other hydrating fluids include plain coffee or tea, sparkling or flavored waters, 100% vegetable juice, and milk or milk alternatives.

It’s best to travel while "well-exercised," Siegel said.

"If you have a regular exercise routine, I wouldn't suspend it a week before travel," he said.

'HOLIDAY SHOPPING WIPES ME OUT, HOW CAN I KEEP UP MY STAMINA?': ASK A DOCTOR

"If you're regularly exercising, sleeping right and eating right before you go, I think that that puts you in much better shape when you're traveling."

Siegel said he’s a "big believer" in wiping down surfaces, especially when traveling by plane.

"You wouldn't believe what these surfaces carry — we've studied that," he said. "There are a lot of germs in that tray table, and it's the person next to you who could be sick." 

"When you're about to take a trip, it is a good time for you to think about whether you’re up-to-date on your vaccines," Siegel said.

One immunization that isn’t given enough attention, according to the doctor, is Tdap, a combination vaccine that protects against tetanus, diphtheria and pertussis (whooping cough).

It is given at least once every five to 10 years.

COVID VACCINE DISTRUST GROWING AMONG AMERICANS

"There's a ton of whooping cough around this year," Siegel said. "Thousands of cases are reported, but many thousands aren't."

The doctor also recommends the shingles shot for those over the age of 50 and the pneumonia vaccine for people 60 and older.

"When you're under stress from travel, that might be when you could get sick," Siegel said, as the immune system isn't functioning at an optimal level. 

"That's when shingles might reappear," he warned. "Shingles is actually a chickenpox virus that's dormant in your body for years, but can recur at times of stress."

The Centers for Disease Control and Prevention (CDC) also recommends that everyone 6 months and older receives COVID and flu vaccinations, with rare exceptions.

For those who take multiple daily medications, the doctor recommends traveling with one pill bottle and putting the various pills in it, making it less likely for any to get misplaced.

"Make sure you have more than enough," he advised. "You never know when you're going to get delayed, especially around holiday travel."

Siegel recommends bringing three or four extra days of pills for all medications.

"Depending on what chronic illnesses you may have, it's a good idea to be up-to-date with blood draws and visits to your doctor" before traveling, he added.

It can be challenging to maintain a regular sleep cycle while traveling, Siegel noted, especially when time zones are changing.

"The more you can catch some winks while traveling, the better off you're going to be," he said.

SLEEP AND TRAVEL DON’T ALWAYS MIX: HERE ARE 7 TIPS TO HELP YOU REST ON THE ROAD

For those who have trouble falling asleep while on the road, Siegel recommends identifying what makes you drift off at home and using those same techniques.

"I get asked a lot for sleeping aids," he said. "For people who are traveling on long trips, I personally am uncomfortable giving medication if the patient hasn't been taking it already."

While masks "got a bad name" during the pandemic because of mandates, Siegel noted that they are tools that can be used for those who are ill or at a higher risk.

"If you're a person who’s at risk of an infectious disease or has a chronic illness, the last thing you need is to get the flu, COVID or RSV."

The doctor recommends considering a mask for tight spaces where there are a lot of people around.

"You don't know what they have or what they are harboring," he said.

"That's why I would consider one, especially if you're at high risk."

Overall, Siegel said, "staying hydrated, eating right and sleeping properly as best as possible is the way to go in decreasing stress while traveling."
