Journal Title: Shanghai Journal of Preventive Medicine - Year 2023, Vol 35, Issue 7
Abstract
ObjectiveTo analyze the epidemic trends and current status in the prevalence of schistosomiasis in Jiangxi Province from 2002 to 2021ï¼ and to provide evidence for formulating and optimizing schistosomiasis control strategies in the province.MethodsEpidemiological data of schistosomiasis in Jiangxi Province from 2002 to 2021 were collected. The Joinpoint regression model was used to investigate the epidemic trends of schistosomiasisï¼ and the annual average percent change ï¼AAPCï¼ was used to assess the changing trend of schistosomiasis infection in humans and bovines. SPSS 25.0 software was used to analyze the target achievement statusï¼ infection rate of schistosomiasis in humans and the areas with snails in 2021 to evaluate the differences among various districts and epidemic regions.ResultsBy 2021ï¼ 24 counties ï¼61.50%ï¼ in the province had achieved the elimination goalï¼ with hilly and marsh counties reaching 82.60% and 31.30%ï¼ respectively. The seropositive rate of schistosomiasis in human was 3.51% across the province. Howeverï¼ the seropositive rate in marshland areas ï¼4.77%ï¼ was significantly higher than that in hilly areas ï¼1.23 %ï¼ ï¼Ï2=3 827.51ï¼ P<0.001ï¼. The total area with snails in the province was 84 938.32 hm2ï¼ including 82 196.86 hm2 in marshland areas and 2 741.46 hm2 in hilly areas. From 2002 to 2021ï¼ the infection rate of schistosomiasis in the humans and bovines exhibited a declining trendï¼ with AAPC values of -48.70 and -39.70ï¼ respectively. The decline rate in the hilly areas was higher than that in marshland areas. Howeverï¼ the area with snail showed an upward trend ï¼AAPC=0.50ï¼ï¼ with a growth rate of 5.80% in hilly areasï¼ which was greater than that in marshland areas ï¼0.40%ï¼.ConclusionFrom 2002 to 2021ï¼ the infection rate of schistosomiasis in humans and bovines in Jiangxi Province continued to declineï¼ while the areas with snails increased. The prevention focus should still be on the marshland endemic areasï¼ and attention should also be given to the risk of schistosomiasis in hilly endemic areas. Thereforeï¼ it is necessary to continue implementing a comprehensive prevention and control strategy that emphasizes controlling the sources of infection and adopts tailored measures based on local conditions and precise policies.
