Abstract

Abstract

Objective To analyze the spatial and temporal characteristics on measles of infants under 1 year old in Henan Province during 2015-2019, to provide evidence for the prevention and control of measles. Methods Data were collected from the Infection Disease Reporting Information System in China and the National Measles Surveillance System. The epidemiological characteristics on measles of infants under 1 year old in Henan Province during 2015-2019 were described. Spatiotemporal distribution and clustering were analyzed by using the ArcGIS 10.7 software and SaTScan 9.4 software. Results A total of 2 757 measles infants under 1 year old were found in Henan Province from 2015-2019 with an average annual incidence of 42.82/100 000. Most cases aged between 6-8 months old, accounting for 49.40% of the total number of cases. The epidemic peak was between January and May. The trend surface analysis found that the incidence of measles decreased gradually from the southern to northern parts, which showed an inverted U type curve. The spatiotemporal scan found three spatiotemporal aggregation areas, and the strongest areas were located in Pingdingshan and Nanyang Districts, which including 28 counties in 2015. Conclusion The incidence rate of measles infants under 1 year old was decreasing year by year and showing obviously seasonal rule in Henan Province, 2015-2019. Infants aged 6-8 months old are the main group of patients. The main clustering areas were located in the south central part of Henan Province, suggesting that the prevention and control measures should be further strengthened in these areas.
