With the holiday season approaching, so does the annual flu season, a time when influenza viruses spread widely. According to the Centers for Disease Control and Prevention, February historically marks the peak of flu activity. To reduce the risk of contracting the flu, health experts strongly recommend getting a flu shot, as anyone over the age of 6 months should be vaccinated annually.
Dr. Matthew Heller, an associate professor of family medicine at New York Institute of Technology College of Osteopathic Medicine, stresses the importance of vaccination. "Always talk to your physician about potential exceptions and find out whether the flu vaccine is appropriate for you," he advises. The vaccine works by stimulating the body to develop antibodies that protect against the flu virus. Even if a vaccinated person catches the flu, they are likely to experience milder symptoms and fewer complications. During seasons when the vaccine is less effective due to virus mutations, it still reduces hospitalizations, deaths, and outpatient visits across all age groups. Importantly, Heller emphasizes that the flu vaccine cannot cause the flu, as it is developed from inactivated viruses.
Getting vaccinated promptly is crucial because it takes about two weeks for the body to build full immunity. Flu symptoms include fever, chills, body aches, cough, headache, and fatigue. People typically become contagious a few days after exposure and may not show symptoms immediately. Symptoms can last about a week. While most healthy individuals can recover at home with rest and fluids, those in high-risk groups—such as adults 65 and older, young children, pregnant women, and people with chronic conditions—should contact a physician if they suspect the flu.
Beyond vaccination, Heller recommends preventive measures like frequent hand washing, using hand sanitizer, sanitizing high-touch surfaces, avoiding touching the face, steering clear of large crowds, and sneezing into a tissue or elbow. These actions help curb the spread of the virus. As a physician, Heller underscores the broader impact of vaccination: "The flu spreads easily from person to person. Remember that getting the flu vaccine will not only protect you but will also protect all those around you. By setting the example, others will follow." His insights reflect the ongoing commitment of New York Tech faculty to address real-world health challenges. For more information, visit nyit.edu.
