Influenza patients should not drink alcohol because they are already experiencing reduced immune function due to the infection with the influenza virus, which is a highly contagious respiratory disease. The influenza virus typically shows a seasonal pattern, with higher incidences in the winter and spring seasons, and it can be transmitted through the respiratory tract to people with weakened immune systems. Therefore, once influenza is definitively diagnosed, it is crucial to promptly provide antiviral treatments, clear heat and detoxify, as well as reduce fever and handle other symptoms, to effectively control the discomfort caused by the virus. Influenza patients should avoid spicy and irritating foods in their diet, and they should drink plenty of water and consume fresh vegetables and fruits. It is absolutely essential to avoid alcohol to prevent exacerbating the symptoms of the influenza virus.
