2. Enterovirus
Most people have encountered the enterovirus at some point. There are many types and, thankfully, they only usually cause mild symptoms. In some instances, the host may not even experience any symptoms at all. When symptoms do arise, it is usually in young people, because adults have had time to develop an immunity.
The virus is usually contracted in summer and fall, and it can cause hand, foot, and mouth disease, as well as summer flu. Somebody with the virus can develop tonsillitis. While they are mostly harmless, some rarer types can be more severe, potentially causing illnesses such as polio and meningitis.
