There are hundreds of different types of virus that can cause a cold, which explains why children get repeated colds.
The flu virus is constantly changing its structure, so new strains appear each year
Flu is caused by the influenza virus. There are three major types: A (often the cause of flu epidemics), B and C. The flu virus is

in children. These infections need to be treated by a doctor.
