Adenovirus

An adenovirus is a medium sized virus in the range of 90-100nm. This virus is non-enveloped and has a double stranded linear DNA genome. The strand of DNA is between 26 and 45 Kbp allowing it to have theoretically, between 22 to 40 genes. There are 53 serotypes or versions of this virus in humans which are responsible for 5-10% of upper respiratory infections. The virus got its name because it was originally isolated from human adenoids. The adenovirus has a unique spike or fiber on the capsid that allows the virus to attach to the host cell. Adenoviruses are resistant to chemical and physical agents as well as adverse ph conditions. This characteristic allows them to survive for extended periods of time outside of the human body. In the past U.S. Military recruits were vaccinated against two serotypes of the adenovirus. There are currently no vaccines against the adenovirus and the best way to prevent a viral infection is by washing your hands routinely.
