Types of Viral Infections. Viruses can affect any part of the body or body system, and can cause infections such as the common cold, flu, gastroenteritis, chicken pox or herpes. The most common type of viral infections involves the respiratory tract. viral infection is any type of infection that is caused by a virus, which is even smaller than bacteria and is encapsulated by a protective coating, so it is more difficult to kill than bacteria. Viral infections involve a dormant virus getting into a living cell and re-writing the cell's genetic codes with its own.
