As winter intensifies, experts warn of a surge in viral infections, including swine flu, influenza, and COVID-19. Dr. Nikhil Modi, a pulmonologist, explains that the colder temperature, increased moisture, low wind speed, and pollution contribute to these infections. Hospitals are experiencing a rise in patients with symptoms such as cough, cold, fever, breathing problems, and pneumonia. To prevent infections, Dr. Modi recommends staying indoors, covering the body adequately, consuming nutritious food, maintaining cleanliness, and wearing masks.
