BACKGROUND: Measles virus (MV) RNA was detected 1 month after hospitalization with
measles in more than half of Zambian children but the duration of detectable RNA was not
determined. OBJECTIVES: To characterize the time course of MV clearance and identify
factors associated with presence of viral RNA at late times after clinical recovery from
infection. STUDY DESIGN: Blood, urine and nasopharyngeal specimens from 49 Zambian
children with laboratory-confirmed measles were collected a median of 100 days (range 65 …
