Abstract

Its manifestations in immunocompetent hosts are unknown.objectives to determine whether HHV-8 primary infection is symptomatic in immunocompetent children and to identify the epidemiological and virological correlates of HHV-8 infection. design and setting prospective cohort study conducted in the pediatric emergency department of a hospital in alexandria, egypt, between december 1, 1999, and april 30, 2000.patients eighty-six children aged 1 to 4 years who were evaluated fora febrile syndrome of undetermined origin. main outcome measures serological assay and polymerase chain reaction of blood and saliva samples for HHV-8, Information on potential risk factors for HHV-8 infection was also collected.results thirty-six children (41.9%) were seropositive; HHV-8 DNA sequences were detected in 14 (38.9%) of these 36 children (detected in saliva in 11 of 14). significant associations were found between HHV-8 infection and close contact with at least 2 other children in the community (36 of 63 vs 6 of 23 for <2 children; adjusted odds ratio [OR], 3.50; 95% confidence interval [CI], 1.11-12.22) and admission to the emergency department in December or January (28 of 47 vs 14 of 39 for february-april; adjusted OR, 3.15; 95% Cl, 1.23-8.58).
