Measles is a significant cause of childhood morbidity and mortality in Nigeria. We described the epidemiologic pattern of measles infection and the performance of the surveillance. The measles surveillance data for Lagos between 1st January and 31st December was reviewed. A total of 615 suspected measles cases were seen. Cases investigated within 48 hours was 222 (36%) (target % less than 80%). Under 1year attack rate (8.33/100,000) was higher than 1- 4 years attack rate (3.48/100,000) (p= 0.01). Proportion of unvaccinated cases was 36%. The surveillance needs to be strengthened. Proportion of unvaccinated cases is high suggesting low vaccine coverage among susceptible.
