Each child's saliva was tested weekly for HHV-6
and parents maintained a daily log of signs and symptoms of illness in their children.
The neurotropism of HHV-6
and that the CNS may be a site of viral persistence or latency are well recognized (8,9).
Seroprevalence of HHV-6
reaches >80% in children >2 years (1-3).
infection is so prevalent, but so few children get LCH, our results suggest that the virus interacts with some underlying predisposition to the disease," said Dr.
