HHV-6B saliva viral loads peak 3-7 months after primary infection

In All, Epidemiology by Kristin Loomis

A new study on HHV-6B shedding in saliva during and after exanthema subitum found that peak detection rates and viral loads occurred during the convalescent period, between 3 to 7 months post-illness. Detection rates were lower in adults than in children suggesting that siblings may be more likely to transmit the virus than parents.
