A unique feature of herpesviruses is their ability to establish latent infection within the nervous system by colonizing peripheral sensory ganglia, which results in subsequent episodic outbreaks of infection triggered by precipitating events. Despite the latent nature of both herpes simplex virus type 1 (HSV-1) and varicella-zoster virus (VZV) within these sensory ganglia, simultaneous outbreaks of these viruses are uncommon. This is generally attributed to the differing reactivation features of these 2 viruses. Four cases of concurrent HSV-1 and VZV infection are described in the literature. We report concurrent infection of HSV-1 and VZV within the same V2 dermatome in an immunocompetent patient.
