Printed In U.S.A. Increased Childhood Morbidity After Measles Is Short-term in Urban

measles cases compared with age-matched children without measles (unexposed) was determined by weekly interview for 6 months. Compared with unexposed children, there were higher incidences of hospitalization (adjusted rate ratio (RR) = 3.1, 95 % confidence interval (Cl): 1.3, 7.6) and bloody diarrhea (adjusted RR = 2.7, 95 % Cl: 1.4, 5.1) in hospital measles cases during the 6 weeks after recruitment. Among community cohorts, there were higher incidences of bloody diarrhea (adjusted RR = 4.1, 95 % Cl: 1.1, 14.6), watery diarrhea (adjusted RR = 1.6, 95 % Cl: 0.9, 2.7), fast breathing (adjusted RR = 3.8, 95 % Cl: 2.1, 6.9), and the weekly point prevalence of pneumonia (adjusted prevalence ratio = 3.1, 95 % Cl: 1.0, 9.8) in measles cases during the same period. All measles cases regained lost weight within about 6 weeks. The prevalence of anergy to seven recall antigens 6 weeks after recruitment was higher in both hospital (adjusted odds ratio = 2.8, 95 % Cl: 1.2, 6.4) and community (adjusted odds ratio = 3.1, 95 % Cl: 1.1, 8.9) measles cases. Morbidity increased during the first 6-8 weeks after measles, but the authors found no consistent evidence of longer-term morbidity or wasting. The results support recent findings that measles is not associated with increased delayed mortality.
