BK Virus Infection
Medically reviewed by Drugs.com. Last updated on Jun 6, 2023.
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.
Seek care immediately if:
- Your symptoms get worse and do not go away even after you take pain medicine.
- You have severe pain when you urinate.
- Your urine has blood in it.
Call your doctor if:
- You have a fever.
- You have trouble urinating.
- You have questions or concerns about your condition or care.
- Medicines may be used to decrease pain, help your immune system, or kill the BK virus.
- Prescription pain medicine may be given. Ask your healthcare provider how to take this medicine safely. Some prescription pain medicines contain acetaminophen. Do not take other medicines that contain acetaminophen without talking to your healthcare provider. Too much acetaminophen may cause liver damage. Prescription pain medicine may cause constipation. Ask your healthcare provider how to prevent or treat constipation.
- Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell your provider if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.
Drink liquids as directed:
Ask your healthcare provider how much liquid to drink each day and which liquids are best for you.
Prevent the spread of germs:
- Wash your hands often. Wash your hands several times each day. Wash after you use the bathroom, change a child's diaper, and before you prepare or eat food. Use soap and water every time. Rub your soapy hands together, lacing your fingers. Wash the front and back of your hands, and in between your fingers. Use the fingers of one hand to scrub under the fingernails of the other hand. Wash for at least 20 seconds. Rinse with warm, running water for several seconds. Then dry your hands with a clean towel or paper towel. Use hand sanitizer that contains alcohol if soap and water are not available. Do not touch your eyes, nose, or mouth without washing your hands first.
- Cover a sneeze or cough. Use a tissue that covers your mouth and nose. Throw the tissue away in a trash can right away. Use the bend of your arm if a tissue is not available. Wash your hands well with soap and water or use a hand sanitizer.
- Clean surfaces often. Clean doorknobs, countertops, cell phones, and other surfaces that are touched often. Use a disinfecting wipe, a single-use sponge, or a cloth you can wash and reuse. Use disinfecting cleaners if you do not have wipes. You can create a disinfecting cleaner by mixing 1 part bleach with 10 parts water.
- Ask about vaccines you may need. No vaccine is available for BKV, but vaccines can help prevent some diseases caused by viruses and bacteria. Vaccines can help protect your immune system. Get the influenza (flu) vaccine as soon as recommended each year. The flu vaccine is usually available starting in September or October. Flu viruses change, so it is important to get a flu vaccine every year. Get the pneumonia vaccine if recommended. This vaccine is usually recommended every 5 years. Your provider will tell you when to get this vaccine, if needed. Your healthcare provider can tell you other vaccines you should get and when to get them.
Follow up with your doctor as directed:
Write down your questions so you remember to ask them during your visits.
