What are the symptoms of the flu？

The symptoms of the flu are mainly reflected in the upper and lower respiratory tract. Influenza usually occurs in winter. May be localized community outbreaks, epidemic dissemination, or pandemics.

Influenza is a viral infection. It attacks your respiratory system. That is, the nose, throat and lungs. Influenza is often called the flu, but is different from the gastrointestinal “flu” virus that causes diarrhea and vomiting.

Most people’s flu goes away on its own. But influenza and its complications can sometimes be fatal.
