| dc.description |
A measles epidemic occurred in the city of Bongor, Chad, from 22 September 1993 to 26 June 1994. A total of 792 patients were hospitalized, with a case fatality rate of 5.2%. After the epidemic, the district management team evaluated the expanded programme on immunization (EPI). Through a cluster survey the attack rate was estimated to be 29.1% (95% confidence interval (CI) = 20.4-37.8%) for the age group 12-59 months (n = 206). For this same age group, the measles immunization coverage was estimated to be 44.2% (95% CI = 34.6-53.8%) and the vaccine efficacy 9.5% (95% CI = 0-41.5%). Several flaws in the logistic handling of the vaccines and especially in the cold chain were identified. These results indicated a serious management problem in the EPI, which the district team then immediately started to rectify. The method used to estimate the immunization coverage and efficacy in the study is rapid and low cost. Also, it is feasible at the district level and permits identification of management problems in the EPI. |
