           region reported,current address,date of onset,date of death,age,sex and occupation. The population information includes
           the resident population and sex ratio. Meteorological data includes AP,ARH,AT,MaT,MRH,MiT,PR and SD. SPSS
           23.0 was used for descriptive statistical analysis and tested to learn the correlation between HFRS cases and meteorological factors
           with ARIMA. Results The average annual incidence of HFRS in Guangdong from 2015 to 2020 was 0.23/100,000,showing a
           fluctuating downward trend. The confirmed cases of HFRS in Guangdong totalled 1 627 as its fatality rate was 0.18%. The ratio of
           clinical cases vs confirmed cases was 1∶2.36 (690/1 627),as the number of cases in Guangzhou,Dongguan and Shenzhen
           accounted for 63.24% (1 029/1 627). The temporal-spatial clusterings featured in Guangzhou clustering (38.3%,of which
           Guangzhou accounted for 75.6%) and Dongguan clustering (61.7%,of which Dongguan accounted for 27.8%). The incidence
           peaks were in January and March to May. The sex ratio (male/female) was 3.11∶1 and these coefficient of variations(CV)
           were 30% and 41%,respectively,the later suggested a greater chance of susceptibility in females. The 25-50 year-old group
           accounted for 62.75%,where the statistical differences existed among the yearly age-groups (P=0.031). The occupations
           included mainly housework and unemployed,business service,labor and farmer,occupied 70.68%. The results included that
           HFRS cases were significantly correlated with relative humidity (ARH,MRH;Lag4M),sunshine duration and precipitation (SD,
                                                     2
           PR;Lag2M) (P<0.05). The ARIMA(1,1,0)(R stationary =0.710) predicted the HFRS cases in the first half of 2021,
           with(61±18)% of the agreement rate between the fitted value and the measured value. Conclusion The HFRS epidemic in
           Guangdong from 2015 to 2021 showed a fluctuating downward trend;high humidity and precipitation might increase the level
           of HFRS epidemic in the next seasonal quarter. For the clustered HFRS epidemic areas in both Guangzhou and Dongguan,the
           current HFRS prevention and control mission is to strengthen field protection to HFRS and improve the laboratory diagnosis rate of
           clinical HFRS cases.
