BK Virus Infection


A BK virus (BKV) infection is a common viral infection that usually does not cause problems. The virus normally remains inactive in your body when your immune system is strong. If your immune system becomes weak, the virus may become active and you may have symptoms.

  • Antiviral medicine may be used to kill the BK virus.
  • Antirheumatic drugs may be used to help your immune system and kill the BK virus.
  • Pain medicine may be given to decrease pain. Do not wait until the pain is severe before you ask for more medicine.


  • Blood and urine tests will show if you are infected with the BK virus. They can also check your kidney function and get information about your overall health.
  • A kidney biopsy is a procedure to remove a small amount of tissue from your kidney to see if you are infected with the BK virus.


  • Bladder irrigation is done to rinse your bladder and help you pass urine.
  • Hyperhydration helps flush your bladder. You may be given liquids to drink or through an IV.


Your healthcare provider may need to decrease your dose of antirejection medicine if you have had an organ transplant. This may cause your body to reject the transplanted organ. Bladder irrigation may damage your bladder. If a BKV infection is not treated, it may cause your symptoms to get worse. A BK infection may cause your kidneys or other organs to fail, and may become life-threatening.
