Description

Three days after initial development, a secondary diffuse vesicular papuloblistering rash developed on the trunk, resembling varicella zoster virus (VZV) infection (figure 2).

Vesicular fluid from both rashes was positive for VZV on Fast Track Diagnostic multiplex real-time PCR assay, which has a specificity of 100% and sensitivity of 100% to 103 copies/mL dilution. Other methods of detection include directly with viral isolation and culture, detection of antigen in cell specimens, visualisation via light microscopy with Tzanck smears or electron microscopy or indirectly with western blotting or IgG detection.1 Further samples were sent for bacterial and fungal microscopy,...
