What is the New Flu Virus Variant?

Posted on January 23, 2026 by Patrick Hercules

There is a new variant of the flu virus called H3N2 subclade K that is affecting the U.S. this flu season, after circulating in other countries last summer.

This variant is a mutated strain of H3N2, which is a subtype of influenza A. According to the Centers for Disease Control and Prevention (CDC), H3N2 is the main type of flu spreading in the U.S. as of mid-November.

Additionally, scientists from around the world have reported that H3N2 subclade K, a mutation of H3N2, has undergone several mutations, which haven’t been seen before in flu viruses. These mutations may make this new strain more severe than usual, with some experts believing that these changes could reduce how well the current flu vaccine prevents infection.

However, it is important to note that it is still recommended to receive the flu vaccine, as the CDC notes that the H3N2 subclade K strain can cause severe symptoms in older adults over the age of 65 and children under the age of five. Other people who are vulnerable to severe symptoms of the subclade K strain include:

Anyone who is immunocompromised

Pregnant people

People with underlying chronic conditions such as diabetes, heart disease, or lung disease

Doctors warn that flu infections, if left untreated or not treated early enough, can increase the risk of complications such as ear infections and sinus infections, as well as more severe complications, including pneumonia, hospitalization, and even death.

In 2024, data from the CDC showed that the U.S. had the most total flu-related hospitalizations in about 15 years, and close to 280 pediatric deaths from the flu.

During this current flu season, the CDC has reported an estimate of 18 million cases, 230,000 hospitalizations, and 9,300 deaths nationwide, with 32 of those deaths being pediatric. What’s more, the CDC says that among the children eligible for the flu vaccine and with known vaccination status, 90% of pediatric deaths this season were among children not fully vaccinated against influenza.

People who are infected with the flu typically develop symptoms within one to four days after exposure. Flu symptoms include:

Fever and chills

Muscle and body aches

Headaches

Sore throat

Cough

Deep fatigue or tiredness

Runny nose or stuffy nose

Vomiting and diarrhea (in some cases, especially in children)

For most healthy people, the flu resolves within a week or two with rest and fluids. However, certain symptoms are red flags that indicate you need to seek immediate medical attention.

Difficulty breathing or shortness of breath

Persistent pain or pressure in the chest or abdomen

Persistent dizziness, confusion, or inability to wake up

Seizures

Not urinating, which is a sign of severe dehydration

Severe muscle pain

A high fever that does not respond to fever-reducing medication

Symptoms that improve but then return with a fever and worse cough

It is important to remember that getting vaccinated is the best way to prevent serious symptoms of the flu virus. There are also several steps you can take to reduce your risk of getting and spreading the flu. They include:

Washing your hands frequently with soap and water.

Avoiding touching your eyes, nose, and mouth.

Staying home when you are sick to prevent the spread of the virus to others.

Covering your cough and sneeze with a tissue or your elbow.

Considering wearing a mask in crowded indoor spaces, especially if you are around high-risk individuals.

If you or a loved one is experiencing any flu symptoms, you can receive treatment from a neurologist at Flushing Hospital Medical Center’s Ambulatory Care Center. To schedule an appointment, please call (718) 670-5486.

The Importance of Getting Vaccinated During Cold and Flu Season

Posted on December 10, 2025 by Patrick Hercules

Flu season can be unpredictable, as it can begin as early as fall and can last until spring. Flu activity is usually at its peak during winter, and public healthcare professionals, advocates, and communities come together to promote flu vaccination as the flu can cause serious health complications, such as bacterial infections or pneumonia. If it isn’t treated in time, the flu can even lead to death.

Vaccination is particularly important for people who are at higher risk of developing serious flu complications, including pregnant women and young children. Millions of children get sick with the flu every year, and thousands will be hospitalized as a result. Women are also at higher risk of developing serious flu complications during pregnancy.

Since flu viruses are constantly changing and protection from vaccination decreases over time, getting a flu vaccine every year is the best way to reduce your risk of the flu. A flu vaccine is the only vaccine that protects against the flu and has been shown to reduce the risk of illness from the flu, hospitalization, and death.

During flu season, we encourage everyone six months and older to get their annual flu vaccine, especially pregnant women, young children, and other people who are at a higher risk of developing serious flu complications. The more people who get vaccinated against the flu, the more people who will be protected from it.

If you or a loved one would like to get the flu vaccine, you can visit Flushing Hospital Medical Center’s Ambulatory Care Center. To schedule an appointment, please call (718) 670-5486.

Pneumonia

Posted on November 13, 2025 by Patrick Hercules

Pneumonia is an infection that inflames the air sacs in one or both lungs. The air sacs may fill with fluid or pus, causing a cough with phlegm or pus, fever, chills, and difficulty breathing.

Pneumonia can range in severity from mild to life-threatening. It is more serious for infants and young children, people older than 65 years old, and people with health problems or weakened immune systems.

The signs and symptoms of pneumonia can vary depending on factors such as the type of germ causing the infection, age, and overall health. Signs and symptoms of pneumonia may include:

Chest pain when breathing or coughing

Confusion or changes in mental awareness; this occurs in adults 65 or older

A phlegm-producing cough

Fatigue

Fever, sweating, and shaking chills

Lower than normal body temperature; this occurs in adults older than 65 and people with weakened immune systems

Nausea, vomiting, or diarrhea

Shortness of breath

Many germs can cause pneumonia. The most common are bacteria and viruses in the air we breathe. The body usually prevents these germs from infecting the lungs, but these germs can sometimes overpower the immune system, even if a person is generally healthy.

Pneumonia is classified according to the types of germs that cause it and where the infection was contracted.

Community-acquired pneumonia is the most common type of pneumonia. It occurs outside of hospitals or other healthcare facilities. It may be caused by:

Bacteria

Bacteria-like organisms

Fungi

Viruses, such as COVID-19

Some people can get pneumonia during a hospital stay for another illness. Hospital-acquired pneumonia can be serious because the bacteria causing it may be more resistant to antibiotics and because the people who get it are already sick. People who are on breathing machines, often used in intensive care units, are at a higher risk of this type of pneumonia.

Healthcare-acquired pneumonia is a bacterial infection that occurs in people who live in long-term care facilities or who receive care in outpatient clinics, including kidney dialysis centers. Like hospital-acquired pneumonia, healthcare-acquired pneumonia can be caused by bacteria that are more resistant to antibiotics.

Aspiration pneumonia occurs when a person inhales food, a drink, vomit, or saliva into their lungs. Aspiration is more likely if something disturbs the normal gag reflex, such as a brain injury or swallowing problem, or excessive use of alcohol or drugs.

There are many steps you can take to prevent pneumonia, including:

Getting vaccinated

Making sure children are vaccinated

Practicing good hygiene

Quitting smoking

Keeping your immune system strong

To diagnose pneumonia, a doctor will start by asking about your medical history and performing a physical exam, including listening to your lungs with a stethoscope to check for abnormal bubbling or crackling sounds that may suggest pneumonia.

If pneumonia is suspected, a doctor may recommend the following tests:

Blood tests

Chest X-ray

Pulse oximetry

Sputum test

A doctor might order additional tests for a person 65 years or older, is in the hospital, or has serious symptoms or health conditions. These tests may include a CT scan and/or a pleural fluid culture.

Treatment for pneumonia involves curing the infection and preventing complications. People who have contracted community-acquired pneumonia usually can be treated at home with medication. Although most symptoms ease in a few days or weeks, the tiredness feeling can persist for a month or more. Specific treatments depend on the type and severity of pneumonia, age, and overall health. These treatments include:

Antibiotics

Cough medicine

Fever reducers/pain relievers

If you or a loved one is experiencing symptoms of pneumonia, you can receive treatment from a physician at Flushing Hospital Medical Center’s Ambulatory Care Center. To schedule an appointment, please call (718) 670-5486.

Flu Season Precautions

Posted on December 20, 2024 by Patrick Hercules

We are in December and physician’s offices and hospital emergency rooms are reporting flu cases. No one wants to catch the flu, so it is important to take proper precautions to help keep you and others healthy.

Here are a few ways we can prevent getting the flu:

Everyone who is six months and older should get vaccinated every year
Avoid close contact with people who are sick
Wash your hands frequently with soap and water
Keep hand sanitizer handy for the times when soap and water aren’t available
Avoid touching your hands to your eyes, nose, and mouth
Disinfect surfaces that are frequently used by others often
Clean your drinking glasses and dishes with hot soapy water
Keep your immune system healthy by eating a balanced diet, exercising regularly, and getting a good night’s sleep
Tobacco can suppress the immune system, so it is recommended to quit smoking

If you are experiencing flu symptoms, visit Flushing Hospital Medical Center’s Ambulatory Care Center. To schedule an appointment, please call (718) 670-5486. If there is an emergency, please call 911.

Everything You Should Know About the Bird Flu Virus

Posted on May 15, 2024 by Jacob Lobosco

You may have recently heard about the spread of the H5N1 bird flu virus among poultry and dairy cows in the United States. Currently, the Centers for Disease Control and Prevention (CDC) estimates that the risk to public health posed by this virus is low; however, the situation is being monitored closely, and it’s important for you to know the potential risks posed to humans by H5N1.

So far, the H5N1 strain of the bird flu has infected wild birds in all 50 states and poultry in 48 states. More recently, it has also been discovered in herds of dairy cows in nine states; this is concerning to health experts because it may indicate that the virus could mutate in a way that makes it easier to spread among humans. In fact, a dairy worker had reportedly become infected in April after exposure to infected cows.

The CDC recommends taking certain actions to protect yourself against this virus and prevent it from spreading among human populations. These actions include:

Avoiding direct contact with wild birds as much as possible, particularly if they seem ill or are dead
Avoiding unprotected exposure to live or dead infected animals (particularly dairy cattle) as much as possible
Monitoring and reporting any new symptoms you experience within 10 days of exposure to the virus, particularly respiratory symptoms or eye redness
Getting the seasonal flu vaccine; while this does not reduce your risk of bird flu infection, it is recommended for reducing your risk of co-infection with human influenza viruses

If you have become sick within 10 days of exposure to the bird flu virus, you should isolate yourself at home away from other members of your household and avoid your workplace or school until you are confirmed to no longer have the H5N1 virus.

Poultry products such as chicken and eggs, as well as beef products, can still be consumed safely as long as they’re cooked to an appropriate internal temperature to kill bacteria and viruses. You should avoid consuming raw milk or any products that contain raw milk.

If you become sick with flu symptoms, particularly after potential exposure to H5N1, it’s important that you receive treatment from a doctor as soon as possible. You can schedule an appointment at Flushing Hospital Medical Center’s Ambulatory Care Center by calling (718) 670-5486.

Back-To-School Health Tips

Posted on August 30, 2023 by Jacob Lobosco

Both the new school year and flu season are approaching, and with other viral illnesses such as respiratory syncytial virus (RSV) and COVID-19 continuing to spread, it’s important to prepare your child with effective habits and strategies for staying healthy. Follow these tips to keep them (and the rest of your family) disease-free this fall:

Get your child vaccinated: Many schools require students to receive the immunizations recommended by the Centers for Disease Control and Prevention (CDC) for their age group. This is a simple, effective method for boosting your child’s natural protection against some of the most common diseases they are likely to be exposed to at school.

Emphasize good hand-washing habits: Your child can come into contact with many different types of germs, bacteria, and viruses while they’re at school or traveling to or from home. Some of these substances, such as cold germs, can live for up to 24 hours on hard surfaces and up to an hour on hands; others, such as the flu, can last much longer, living on hard surfaces for up to 48 hours. Regular, thorough hand-washing is essential for minimizing your child’s contact with these germs and reducing their likelihood of becoming infected.

Take your child to a doctor if they feel sick: If your child starts to feel ill, you can reduce the amount of time they spend feeling sick (and, potentially, the amount of school days they may have to miss) by taking them to a doctor right away. A doctor can prescribe certain medications, such as antivirals or antibiotics (depending on whether your child has a virus or bacterial infection), and recommend other medications and treatments for relieving their symptoms effectively.

If your child has an infection, you can receive specialized treatment at Forest Hills Pediatric Specialists. To schedule an appointment or for more information about the office, please call (718) 704-5020.

Does Your Child Have a Viral or Bacterial Infection?

Posted on April 12, 2023 by Jacob Lobosco

Throughout the spring season, there are a number of different ways your child can become sick, leading to common symptoms such as a sore throat, runny nose, fever, or stomach problems. In some cases, these issues may only be a result of seasonal allergies to substances such as pollen. However, these symptoms could also occur due to an infectious disease, such as the common cold or flu.

Children develop infections due to either viruses or bacteria. A virus is a piece of genetic material surrounded by protein that requires a living host; when it infects something, it takes control of the host’s cells and uses them to create more of the virus. Some examples of common pediatric viral infections include:

Influenza
Colds
Respiratory Syncytial Virus (RSV)
Gastroenteritis (Stomach Flu)
Chickenpox
Bronchitis

Bacteria are single-celled organisms that live in a variety of different environments; most cause no harm to humans, with some even aiding in bodily processes such as digestion, but others may cause illnesses to develop in certain parts of the body. Common bacterial infections in children include:

Strep throat
Ear infections
Impetigo

Some infections may also be caused by either a virus or bacteria. These include:

Pneumonia
Meningitis
Diarrhea

Knowing the cause of your child’s infection is important, as this will determine the type of medicine they will need. Viruses are treated with antiviral medication, while bacterial infections are treated with antibiotics. Trying to treat your child’s infection with the wrong type of medication will not work, and in some cases could even lead to negative side effects.

Both antiviral medication and antibiotics can only be obtained with a prescription. A doctor can determine the most likely cause of your child’s infection and prescribe them with the appropriate medication for effective treatment results. You can schedule an appointment with a pediatrician at Forest Hills Pediatric Specialists by calling (718) 704-5020.

National Handwashing Awareness Week

Posted on December 6, 2022 by Flushing Hospital

The first week in December is marked as National Handwashing Awareness Week. Flushing Hospital Medical Center believes that Infection prevention is important to all of us and each of us has a valuable role to play in keeping patients safe from infection.

According to the CDC, handwashing is one of the best “do-it-yourself” precaution —it involves five simple and effective steps (Wet, Lather, Scrub, Rinse, Dry) you can take to reduce the spread of diarrhea and respiratory illness so you can stay healthy. Regular handwashing, particularly before and after certain activities, is one of the best ways to remove germs, avoid getting sick, and prevent the spread of germs to others.

It’s quick, it’s simple, and it can keep us all from getting sick. Handwashing is a win for everyone, except the germs.

Immunity-Boosting Tips To Help You Stay Healthy This Holiday Season

Posted on December 9, 2021 by Michael Hinck

The holiday season is here and to increase your chances of staying healthy and enjoying all the festivities that are associated with this time of year, Flushing Hospital is sharing the following tips to help you boost your immune system and avoid illness during this time of year.

Protect yourself against illness– taking certain preventive measures like washing your hands, wearing a mask whenever possible and taking Vitamin D can decrease your chances of getting sick. Also. getting vaccinated against COVID-19 and the flu can provide protection against serious complications from those viruses.
Get the appropriate amount of sleep – With all the shopping, wrapping, decorating, and baking, the holiday season can be very busy time of year. Even though you might find yourself overwhelmed around the holidays, it’s important to get the recommended amount of sleep each night (seven to nine hours for adults) to help keep your immunity levels high.
Eat healthy – Making healthy and nutritious food choices can give your immune system a big boost. Conversely, making unhealthy food choices can negatively affect your immunity to illness. Some foods that can potentially boost your immune system include garlic, whole grains, such as oats or quinoa, and yogurt.
Make time for exercise – Regular exercise can not only help keep your immune system running by supporting overall health and wellness, but recent research has suggested that it can also boost it by improving circulation, relieving stress, promoting “good” bacteria in your gut.
Enjoy time with family and friends – If the pandemic has taught us one thing, it is the importance that social interactions have on our mental well-being. Spending time with loved ones not only can reduce stress and make us happy, but studies have found that, if done responsibly and when following the appropriate safety precautions, it can also positively impact our immune system.

We hope these wellness tips will help you stay healthy and safe this holiday season.

What Type Of Flu Vaccine Is Best For Seniors

Posted on November 21, 2019 by Michael Hinck

With flu season upon us, it is recommended that everyone six months and older receive their annual influenza (flu) vaccine. This is especially true for senior citizens as they are at a greater risk of developing serious complications from the flu. While there is no debate over whether or not seniors should get their flu shot, there is one about what type of vaccine they should receive.

Many providers are now recommending that patients over the age of 65 receive the vaccine Fluzone, a higher dose injectable vaccine formulated specially for seniors. Like other flu vaccines, Fluzone is comprised of three different strains of the influenza virus that are most likely to cause the flu during the upcoming season. However, Fluzone contains four times the amount of antigen (the inactivated virus that promotes a protective immune response) as a regular flu vaccine and produces a stronger immune response.

This high-dose vaccine was created specifically for seniors because their immune defenses are weakened due to their age. It is estimated that approximately 75% of seasonal flu-related deaths have occurred in people 65 years and older and between 50% and 70% of seasonal flu-related hospitalizations have occurred among people in this age group.

The results of seniors who have taken high-dose vaccines are promising. Initial studies have indicated that 25% fewer cases of influenza occurred in adults 65 years or older who took the high-dose vaccine compared with those who took the standard-dose vaccine, but other studies also revealed that seniors who received the high-dose vaccine were more likely to develop side effects, such as a fever and soreness at the injection site, during the week after vaccination.

If you are over 65 years old and still haven’t received your flu vaccine this year, speak to your doctor about whether or not a high-dose vaccine is right for you.

If you would like to make an appointment with a doctor at Flushing Hospital, please call 718-670-5486.
