Spotting the Signs: Symptoms of Parvovirus B19
Published: Mar 30, 2024
Recognizing the symptoms of parvovirus B19 is key to understanding its impact. From harmless rashes to serious anemia, here's what you need to know.
Classic Symptoms in Children
In children, parvovirus B19 typically causes erythema infectiosum, also known as fifth disease. This presents as a bright red rash on the cheeks, often referred to as the 'slapped cheek' rash. This rash can spread to the trunk and limbs, creating a lace-like pattern. Children may also have a mild fever and feel unwell.
Adult Manifestations
Adults infected with parvovirus B19 might not develop the classic rash but can experience joint pain, particularly in the hands, wrists, and knees. This joint pain is more common in women and can last for weeks. Some adults might also feel fatigued or develop a mild flu-like illness without a rash.
Severe Cases in Vulnerable Populations
For those with chronic blood disorders, parvovirus B19 can lead to a severe drop in red blood cell production, known as transient aplastic crisis, causing extreme fatigue and anemia. Pregnant women are at risk for complications affecting the fetus, such as severe anemia or miscarriage.
Uncommon but Possible: Neurologic Symptoms
Though rare, parvovirus B19 can lead to neurological issues like encephalitis in both children and adults. These symptoms may coincide with a rash or anemia, making early diagnosis and treatment crucial.
