Answer 1

Influenza is an infectious disease that cause viruses. Influenza viruses undergo frequent genetic changes (called mutations), which means that in every season, many people can get sick with influenza. Viruses movebetween sick and healthy people. Influenza is not a "common cold", because influenza viruses are much more dangerous and the consequences of flu can be much more dangerous. For some people,especially with chronic heart, lung or diabetes, influenza can pose a risk tohealth and even life. Therefore, do not underestimate the flu. At the same time it is worth noting that the flu is a disease against which there are effective methods of protection.
