Dr. Jiang Weimin
Influenza A (H1N1) and influenza B are both acute respiratory infectious diseases caused by infection with influenza viruses. These viruses belong to different subtypes of the influenza virus. Influenza A is primarily caused by the influenza A H1N1 virus, while influenza B is caused by the influenza B virus. The main source of these viruses is usually respiratory droplets from infected individuals, such as those released during coughing or sneezing. The viruses can spread through the air and transmit among people, leading to seasonal influenza outbreaks. Timely vaccination against influenza and practicing hygiene measures can help prevent infection.
