In this episode, we tackle the clinical mischief of Parvovirus B19, a common viral infection with a surprisingly wide range of manifestations—from the classic “slapped cheek” rash of erythema infectiosum to aplastic crises in children with hemolytic anemias and fetal hydrops in pregnant contacts. We’ll break down the virology, epidemiology, clinical presentation, and complications of Parvovirus B19. You’ll also learn how to manage exposures in the emergency department, especially when the child has a pregnant caregiver, and why isolation isn’t always necessary once the rash shows up.

Introduction

Necrotizing soft tissue infections can be easily missed in routine cases of soft tissue infection. High mortality and morbidity underscore the need for vigilance.

Definition

A rapidly progressive, life-threatening infection of the deep soft tissues. Involves fascia and subcutaneous fat, causing fulminant tissue destruction. High mortality often due to delayed recognition and treatment.
