Type A influenza infection can be serious and cause widespread outbreaks and disease. Common symptoms of type A infection can be confused with other conditions. While in some milder cases the flu can resolve on its own without significant symptoms, severe cases of type A influenza can be life-threatening.

For most healthy people, the flu is an uncomfortable but short-term illness that resolves itself as the immune system fights it off. Symptoms usually appear from one to four days after exposure to the virus, and they last five to seven days.
Secondly, which is worse influenza A or influenza B?

While influenza B viruses are typically less common than influenza A viruses, influenza B infections can be more severe in children, and can lead to complications that require hospitalization or death.
How serious is type A influenza?
Type A influenza can be dangerous and is known to cause outbreaks and increase your risk of disease. Influenza A mutates faster than influenza B, but both viruses are always changing, creating new strains from one flu season to the next. Past flu vaccinations will not prevent infection from a new strain.
