BK Virus (BKV) is a member of polyoma viruses, a DNA virus in the family Polyomaviridae, which also includes other closely related viruses, JC virus and simian virus 40. BKV is a common cause of asymptomatic infection in immunocompetent individuals. Seroconversion occurs in approximately 70% of the population between the ages of 5 and 8. Human symptomatic infections usually occur in immunocompromised patients. BKV causes cystitis (non-hemorrhagic and hemorrhagic) and ureteral stenosis in bone marrow and solid organ transplant recipients, and polyomavirus-associated nephropathy (PVAN) in renal transplant recipients. The prevalence of PVAN in transplant recipients varies from 1 to 10%, and the rates of allograft loss range from 10 to 80%.
