There are two types of Coxsackievirus, Type A and Type B. Type A viruses cause blisters in the mouth, throat, hands, etc. (HFMD). It can also cause inflammation of the eyelids and white part of the eye. Type B causes fever, lung and abdominal pain, and headaches. It may be a cause for diabetes as well. Both types may cause meningitis and other diseases, but this is less likely.
