Parvovirus B19, humant
Parvovirus B19, human is a single-stranded DNA virus that primarily infects humans and causes a variety of clinical manifestations, most commonly the self-limiting childhood infection known as erythema infectiosum or "slapped cheek syndrome." The virus predominantly targets erythroid progenitor cells in the bone marrow, leading to transient suppression of erythropoiesis and potential anemia, especially in individuals with underlying hemolytic disorders. In immunocompromised individuals, Parvovirus B19 infection can result in chronic anemia and other complications. Additionally, the virus has been associated with fetal loss and hydrops fetalis during pregnancy if the mother becomes infected during critical stages of fetal development.
