What Is Influenza A?
1. Type A Influenza
Influenza, more commonly known as the flu, is one of the most common illnesses that people are likely to have. There are also 4 different types of influenza virus, known as A, B, C and D. Type A influenza is the most common of the influenza viruses, and it is also often the most severe.
Although the type A influenza virus is the most severe, it is still not usually a danger and the vast majority of people with the disease will have only mild symptoms. It can be a lot more dangerous in vulnerable people, however, and those that are at risk should be extra careful to keep themselves safe from the disease.
