Difficult on clinical data alone…viral culture (2-4 weeks), serology by indirect immunofluorescence, cytology on concentrated urine

Experimental live attenuated vaccines are being developed but unknown efficacy or safety.

2. Immunofluorescence: Intense nuclear staining for all herpesviruses
3. ELISA and Western Blot: Specificity based on glycoprotein
5. TORCH: Serologic assay
