What is one method of non-vaccine prevention for the flu?

Covering your face when you cough or sneeze is an effective method of non-vaccine prevention for the flu because it helps to contain respiratory droplets that can spread the virus to others. When an infected person coughs or sneezes without covering their mouth and nose, the flu virus can easily be transmitted through the air, potentially infecting those nearby. By using a tissue, your elbow, or a mask to cover the face, you reduce the likelihood of spreading the virus and contribute to public health efforts to limit outbreaks.

Other methods of prevention, such as drinking plenty of liquids, are beneficial for overall health and can assist in recovery if one is already sick, but they do not directly prevent the transmission of the flu virus. Taking antibiotics is ineffective for viral infections like the flu, as antibiotics only target bacterial infections. Getting a flu shot is a vaccine-based method, which is not applicable in this context since the focus is on non-vaccine prevention methods.
