<abstract xmlns="http://www.w3.org/1999/xhtml"><p> Background: BK virus infection is common but is usually asymptomatic.

Some investigators have studied the pathophysiology and there are anecdotal and uncontrolled studies of therapy with few conclusions allowing treatment guidelines. Objectives: Summarize literature review of current knowledge concerning the nature, epidemiology, pathophysiology, diagnosis and treatment of this common virus infection. Results: HC is a not uncommon and often misdiagnosed infection from BK virus. It is usually self limited but can become life threatening in immune compromised patients. PVAN threatens survival of transplanted kidneys and is difficult to differentiate from rejection without sophisticated molecular diagnostic technology. We have sufficient information for making a diagnosis of BK virus disease by using clinical, serological and molecular technology.
