Abstract:
ObjectiveTo evaluate the measles surveillance system （MSS） in Jiading District， Shanghai from 2020 to 2022， and to provide evidence for the elimination of measles. MethodsDescriptive methods were used to analyze the MSS data and confirmed measles cases from 2020 to 2022 and to evaluate MSS performance indicators. ResultsA total of 120 suspected cases were reported through the MSS from 2020 to 2022， of which 12 were classified as measles， 9 as rubella， and 99 as non-measles /rubella. The incidence of reported non-measles /rubella was 1.44 per 100 000 population in 2020， 2.01 per 100 000 population in 2021， and 1.99 per 100 000 population in 2022. The rates of complete investigation within 48 hours， blood samples and etiology collection， timely delivery， and timely reporting were all 100%. Among the 12 confirmed measles cases from 2020 to 2022， seven routine immunization subjects completed the required doses of measles vaccines， while two out five adult cases had a history of measles vaccine-related immunization. The confirmed cases comprised six with fever accompanied by rash， five with rash alone， and one with fever alone. ConclusionThe MSS results in Jiading District， Shanghai are overall satisfactory. However， there is a need to improve sensitivity， especially in detecting and reporting cases with atypical symptoms. It is imperative to maintain high vaccination coverage for age-appropriate children， promote supplementary immunization activities， and elevate the overall immunity of the entire population.
