Increased susceptibility to herpes simplex virus infections in children with acute measles.
Children with measles treated either in hospital or as outpatients were examined for clinical or laboratory evidence of oropharyngeal herpes simplex virus (HSV) infection. HSV was isolated from 43% of the hospitalized children and 37% of the outpatient children and an additional 9% of the hospitalized group had lesions without the virus being isolated. The incidence of both HSV isolation and clinical lesions in infected children was significantly greater in children hospitalized for measles than in a control group of children hospitalized for tuberculosis. Data from the outpatient group strongly suggest that malnourished children with measles are particularly susceptible to HSV infection. The immunosuppressed state of the children with acute measles was demonstrated by impaired lymphocyte transformation responses to phytohemagglutinin and the inability of their serum to support normal transformation responses by lymphocytes from normal individuals. However the extent of this immunosuppression was unrelated to the susceptibility of the children to HSV infection.
