2. InfluenzaType B

There are 3 main types of the influenza virus that can infect people, one of which is type B, which accounts for around 25% of all cases of the flu. The type B influenza virus can be found in people only. It is not a particularly severe type of the flu, but it can still pose a very real risk to some people. It is also highly contagious.

This type of flu can be found all year round and it will occasionally result in seasonal outbreaks. However, influenza type B viruses do not cause pandemics and they are not classified by subtype. Symptoms of influenza type B virus will typically last for up to 7 days, first appearing up to four days after the patient has been exposed to the virus.
