Parvovirus B19 infection is a common viral illness that spreads from person to person and frequently results in no or few symptoms. The virus can occasionally target cells that develop into red blood cells. Production of these cells is momentarily halted by infection. Only those who don’t produce normal red blood cells will experience the effects of this blockage. The fifth disease, or “slapped cheek” condition, which is highly frequent in school-aged children, is caused by the parvovirus.


Children may experience different parvovirus B19 infection symptoms than do adults. Symptoms include:

  • Fatigue
  • Arthritis
  • Sock And Glove Syndrome (Less Common And Usually In Adults).
  • Headache
  • Minor Fever
  • Joint Pain (Commonly In Adults).
  • Slapped Cheek Disease
  • Swollen Joints (Commonly In Adults).
  • Upset Stomach

Rarely, the parvovirus B19 infection might also stop your body from producing new blood cells in you or your kid. Because it may result in severe anemia, this is a dangerous symptom. This symptom might appear if you have:

  • Poor immune system (causes might be cancer, leukemia, HIV, or an organ transplant)
  • Sickle cell disease or many types of anemia.


Your doctor will examine you physically and inquire about any symptoms you may be having and the medications you are currently taking. Since the illness is frequently asymptomatic (has no signs) or remarkably benign (mild), testing is typically avoided.

If you are at high risk for issues and your doctor believes you have parvovirus B19 infection, your blood, bone marrow, amniotic fluid, or blood from the fetal cord may be tested. They could examine your blood for antibodies if they think you may have had it previously.

If you’re expecting, your doctor could advise further ultrasounds to monitor the development of your fetus.


A parvovirus B19 infection often has a self-limiting course and will go away independently. There is no need for therapy for kids or adults who are typically healthy. But you might want to try these things first:

  • Take Tylenol (acetaminophen) to get relief from your fever and headache
  • For joint discomfort and swelling, use ibuprofen (Advil), a non-steroidal anti-inflammatory medicine.
  • Get adequate rest and a lot of water.

Your unborn child can require a transfusion of fetus blood if they experience severe anemia or hydrops fetalis. Miscarriage and stillbirth are rare possibilities.
