Parvovirus B19 (Erythema infectiosum) mnemonics

Parvovirus is the only single stranded DNA virus.
Parvo is part of double strand, that is, single stranded virus!

Single stranded non enveloped DNA virus

Sorry for the slang, the B looks like buttcheeks and it kinda helps with the slapped cheeks association for parvovirus.

The 5th cranial nerve supplies the cheek, so remember that it is also known as fifth disease.

P for Parvovirus. Polyhydroamnios. hyroPs fetalis. aPlastic anemia, acute arthroPathy.

Best initial test to do in a sickle cell patient with suspected Parvovirus infection is: Reticulocyte count
Confirmatory is: IgM or PCR

That's all!
Lemme know if you have better ones =)
