Parvovirus B19 is the only member of the Parvoviridae family that has been found to infect human hosts.[1] It was discovered in 1974, when a research group looking at hepatitis B surface antigens found a serum sample with unexpected results.[1] Another lab in Japan described a similar virus in 1979 that they called "Nakatami".[1] When compared, the two were found to be identical.[1] In 1985 this virus was officially recognized as a member of the Parvoviridae family due to its similarities in genome size and density.[1]

Infection by Parvovirus B19 (Parvo B19V) causes many diseases, including "fifth disease" in children, aplastic crisis for people with hemolytic anemia, anemia in immunocompromised patients, acute or chronic arthropathy in adults, and fetal hydrops in pregnant women.

Genome Structure

The Parvovirus genome is a single strand of DNA with 5,596 nucleotides, 4,830 of which are coding regions.[1] This region contains 2 large open reading frames.[1] One large non-structural protein is coded by one open reading frame, and the second reading frame codes for 2 capsid proteins.[1]
