Abstract

This study analyzed the temporal-spatial distribution characteristics, epidemiological characteristics and gene sequences of hemorrhagic fever with renal syndrome (HFRS) in Guangxi, with the intention of providing a theoretical and technical support for the prevention of HFRS. A map of the incidence of HFRS of different cities in Guangxi was drawn up using the Geographic Information System (GIS) to investigate the epidemiological characteristics and infection source of HFRS between 2013 and 2016. Guangxi has a low incidence of HFRS, and autumn and winter are the main high-incidence seasons. Cases of HFRS were reported in all regions in Guangxi except Laibin city between 2013 and 2016. The distribution of cases in the four years suggested that Guilin, Nanning, Hechi and Wuzhou were the main infected regions, especially the local areas in the north of Guilin. The nucleotide and amino acid of S fragment and M fragment of Hantaviruses (HV) detected were highly homologous, and no obvious variation was found. Through analyzing the space-time characteristics, epidemiological characteristics and gene sequence of HFRS in Guangxi, it was found that areas rich in water, grass and moisture, such as paddy fields, are the main active areas for the host of HFRS
