Primary Varicella Infection in a Young Adult from the Democratic Republic of the Congo: A Case Report and Mini-Review

Abstract

We describe a case of an immunocompetent adult male patient originally from the Democratic Republic of Congo (DRC), who was referred to our unit for a several-day history of fever and a pruritic, vesicular rash. There was initial concern in the Emergency Department for Mpox (formerly known as “monkeypox”) given the current epidemiology versus other viral etiologies. Primary varicella zoster virus (pVZV) infection was ultimately diagnosed by PCR from a swabbed, unroofed lesion, and he recovered completely with supportive management and without antiviral therapy. We herein describe how common viral exanthems may best be differentiated in an emergency or outpatient setting.
