Clinical course of parvo B19 infection
The incubation period can last up to a few weeks with symptoms typically developing 10 to 14 days later after exposure. Individuals may develop flu-like symptoms and adults may notice a morbilliform rash on their trunk and extremities. The classic presentation of parvo B19 in children is the erythema infectiosum or fifth disease, manifesting as fever and a maculopapular or reticular rash appearing as a bright red facial rash (i.e., slapped cheeks).
