New Delhi India (UNA) :

Flu activity from the H3N2 strain of influenza A is on the rise across many countries as winter approaches. This strain spreads easily in crowded spaces and during travel, leading to a surge in infections and hospitalizations in some regions. Health experts emphasize vaccination and preventive measures to stay safe.

Getting the annual flu shot remains essential, as it reduces the risk of serious illness and complications even if it doesn’t prevent every infection. Practicing regular handwashing, using sanitizer, and avoiding touching your face can further reduce exposure to the virus.

Lifestyle habits also strengthen immunity. Adequate sleep, balanced nutrition, staying hydrated, and regular exercise help the body fight infections. Some people also use vitamin C, vitamin D, and zinc supplements as a supportive measure, though they are most effective alongside a healthy routine.

Health authorities advise that while no method guarantees complete protection, combining vaccination, hygiene, and overall wellness can lower your risk and make any flu infection milder. High‑risk groups  including older adults, young children, pregnant women, and those with chronic illnesses should be especially cautious and consult their doctors about the best protection strategies.
