Abstract：OBJECTIVE To analyze the spatiotemporal distribution patterns of measles outbreaks in Minhang District of Shanghai,in order to provide insights for measles elimination efforts.METHODS Measles incidence data from 1998 to 2021 in Minhang District of Shanghai,were collected.Global and local spatial autocorrelation analyses were conducted to determine spatial differentiation patterns.SaTScan 10.1 software were employed to detect spatial-temporal clusters of measles outbreaks.RESULTS The average annual measles incidence rate in Minhang District from 1998 to 2021 was 5.05/105,showing a significant downward trend.Global spatial autocorrelation analysis indicated no apparent spatial correlation.Local spatial autocorrelation analysis revealed high-high clusters of registered and non-registered populations in Meilong Town from 2014 to 2021.For Huacao area,registered population showed a high-low cluster from 1998 to 2005,while non-registered population exhibited a high-low cluster from 2014 to 2021.Spatiotemporal scan identified three high-incidence clusters,including two clusters among registered populations in 5 townships from 2005 and 4 townships from 2005 to 2008.One spatiotemporal cluster was observed among non-registered populations in 6 townships from 1998 to 2009.CONCLUSION Measles incidence in Minhang District of Shanghai,exhibited spatiotemporal clustering from 1998 to 2021.Enhanced measles prevention and control efforts are needed in the Huacao,Xinzhuang,Zhuanqiao,and Meilong communities.
