This is a retrospective study of the epidemiology and morbidity of herpes zoster and the risk factors for herpes zoster morbidity in Singapore. ⋯ Our study indicated that older patients (aged more than 50 years) were at a higher risk of developing post-herpetic neuralgia. They were also more likely to suffer morbidity, e.g. insomnia. There is a need to educate patients at risk to identify the prodrome and skin eruptions of herpes zoster so that early antiviral therapy can be considered.
