Genotype 1 of human parvovirus B19 in clinical cases.

In São Paulo, Brazil, we performed a study of B19V by monitoring the spread of this virus, which is an infectious agent and could be mistakenly reported as a rash and other types of infection.

Method:: Serum samples were subjected to enzyme immunoassay, real time polymerase chain reaction, and sequencing.
