Abstract:
Objective:To investigate the epidemiological characteristics of measles in Jiaxing City of Zhejiang Province in different immunization program periods, so as to provide the evidence for improving prevention and control strategies of measles.
Methods:Data of measles cases in Jiaxing City from 2005 to 2023 was collected through the Chinese Disease Prevention and Control Information System. Population, temporal, and regional distribution of measles during the periods of pre-expanded immunization program (from 2005 to 2007), expanded immunization program (from 2008 to 2010), and enhanced immunization program (from 2011 to 2023) were descriptively analyzed.
Results:There were 3 997 measles cases reported in Jiaxing City from 2005 to 2023, with an average annual reported incidence of 4.66/105, showing a decreasing trend (P<0.05). The average annual reported incidence of measles during the periods of pre-expanded immunization program, expanded immunization program, and enhanced immunization program were 22.88/105, 7.24/105 and 0.83/105, respectively. The incidence of measles during different stages of immunization strategies all peaked from March to May. The highest reported incidence was 5.94/105 in Pinghu City and the lowest was 3.92/105 in Tongxiang City. The districts with the highest average annual reported incidence in the periods of pre-expanded immunization program, expanded immunization program, and enhanced immunization program were Nanhu District (31.10/105), Pinghu City (11.10/105) and Jiashan County (1.55/105), respectively. There was spatial clustering of measles in Jiaxing City during the period of pre-expanded immunization program (Moran's I=0.787, P<0.05), with a high-high cluster in Nanhu District.
Conclusions:The reported incidence of measles in Jiaxing City showed a decreasing trend from 2005 to 2023. There was a spatial cluster of measles incidence during the period of pre-expanded immunization program, but no significant clusters during the periods of expanded immunization program and enhanced immunization program.
