Slapped cheek rash? It’s Parvovirus B19 causing erythema infectiosum, aka fifth disease. the characteristic rash shows up after the fever, malaise, aches and GI symptoms. Also, remember it can cause fetal anemia, non-immune fetal hydrops and fetal death if a pregnant person is infected. Also bees don’t carry it.

Lyrics

Erythema infectiosum
Fever, aches, malaise it’s true
Initial constitutional symptoms
Sometimes puke and diarrhea too

Once viremia time is gone
Those cheeks are rosy red
You think the child was slapped right there
Across their little head

But it’s just parvovirus
Version bee nineteen
It’s fifth diease I must admit
It’s something you’ve all seen
