Is this year's flu strain A or B?

This year's flu outbreak is mainly caused by the prevalence of H1N1 influenza. H1N1 is a contagious disease caused by infection with the influenza A virus, and it spreads through airborne droplets, direct contact, and close-range transmission. The H1N1 flu season typically begins in winter and ends in spring. Symptoms can range from mild to severe, including fever, fatigue, coughing, and in some cases may progress to pneumonia or other complications. To prevent the spread of H1N1, experts recommend maintaining good personal hygiene, washing hands frequently, eating more vegetables and fruits, engaging in regular outdoor activities, getting sufficient sleep, and properly managing temperature differences between morning and evening. People should avoid crowded workplaces and public areas as much as possible to reduce the risk of infection. It is important to note that individuals experiencing flu-like symptoms should seek medical attention promptly.
