title: Concurrent reactivation of herpes simplex and varicella zoster viruses confirmed by the loop-mediated isothermal amplification assay.
abstract: Concurrent reactivation of herpes simplex and varicella zoster viruses is rare. Here, we describe the case of an elderly patient with herpes labialis and herpes zoster manifesting as a right-side facial eruption with vesicles and crusting. The loop-mediated isothermal amplification (LAMP) assay demonstrated the presence of both herpes simplex virus type 1 and varicella zoster virus in swab samples taken from the face, which was confirmed by real-time PCR, suggesting concurrent reactivation of both viruses. The use of the LAMP assay in the present case indicates its usefulness in the diagnosis of atypical herpes infections.
