[Difficulties in the epidemiological surveillance of measles in Africa: exemplified by the Ivory Coast].
In tropical areas measles cases often are under-reported but the authors comment here two epidemics which had at first been considered as outbreaks of measles but were not. The first epidemic resembled a Chikungunya virus outbreak with important rashes, hyperthermia and pain attacks and was due to Igbo-Ora arbovirus. In the second epidemic children were having rashes with hyperthermia and adenopathy evoking rubella. The authors consider the possibility of over-reporting in view of the surveillance of measles, the target-disease in EPI (Expanded Programme on Immunization). This hypothesis is confirmed by the distribution of reported cases at national level with a high rate of out-season cases and among adults.
