3. Influenza Virus
The influenza virus is among the best known of all viruses. It is responsible for the illness commonly known as the flu. In the past, the influenza virus has been responsible for countless deaths, but modern medicine means it is now nowhere near as dangerous as it once was.
The flu causes symptoms like fever, chills, aching joints, headache, and swollen tonsils. While it is not as dangerous as it used to be, it does still pose a risk for people who have a weakened immune system. People are encouraged to get regular flu shots in order to keep them protected against the virus as it evolves.
