Analysis and study on the influence factors about meteorology of nororvirus incidence in Lin'an District
Objective To analyze the key meteorological factors affecting the norovirus incidence,to provide technical support for the prevention and early warning of norovirus infectious diseases.Methods The incidence data of norovirus in Lin'an District from January 2017 to December 2019 and the meteorological data of the same period were collected for single factor correlation analysis and multiple regression analysis of meteorological factors and incidence rate.Results The distribution of incidence rates in different seasons were statistically significant(x2=20.05,P＜0.01),of which the incidence rates were higher in winter and spring,while the incidence rates were lower in summer and autumn.The incidence rate of norovirus was significantly negatively correlated with seasonal temperature(r=-0.967,P＜0.05).The incidence rates of norovirus in different months were statistically significant(x2=58.6,P＜0.01).The single factor analysis showed that the monthly average temperature,monthly total radiation and monthly average water pressure were negatively correlated with the incidence rate of norovirus,and the monthly average air pressure was positively correlated with the incidence rate of norovirus.Multiple regression analysis showed that lower temperatures and higher atmospheric pressure environments could increase the incidence risk of norovirus.Conclusion By analyzing the changes and status of various meteorological factors closely related to the onset of norovirus,the change trend of norovirus onset could be comprehensively judged.Disease prevention and control departments could achieve early warning and prevention of norovirus onset by monitoring meteorological data,effectively reduce the risk of norovirus onset.
