  Abstract: Objective To analyze the spatial distribution and accessibility of fever clinics and designated hospitals, so as to provide reference for the allocation of medical resources in response to major infectious disease epidemic events. Methods Taking Hunan Province as the research area, 344 fever clinics and 224 designated hospitals (including backup hospitals) were selected as the research objects. The nearest facility analysis and two-step floating catchment area method were used to analyze the accessibility of fever clinics and designated hospitals. Results There were 0.51 fever clinics per 100,000 people and 1.62 fever clinics per thousand square kilometers in Hunan province. 70.35% (242) were located in secondary medical institutions. 45.25% of residents and 16.31% of areas could reach fever clinics within 15 minutes by car. Fever clinics are mostly located in densely populated areas, showing a spatial pattern of high accessibility to the center of the county and decreasing to the edge. The total number of beds in designated hospitals in Hunan province is 143,500, with 21.19 beds per 10,000 people, and 55.74% (136) of these hospitals are secondary medical institutions. At 0.61h and 1.22h cost impedance, the mean values of accessibility were 3.56±4.83 and 3.91±3.17, respectively, showing a spatial pattern of higher accessibility in the western region and lower accessibility in the high-density region. Conclusion The spatial distribution of fever clinics in Hunan province is relatively balanced among cities and counties. The allocation of cities with higher population density is more, which is conducive to the early detection of cases in cities. However, the basic coverage of the whole region and the majority of residents need to drive for 60 minutes, which affects the function of the sentinel. In Hunan province, the allocation of beds in designated treatment hospitals is sufficient, but the accessibility in urban areas with high population density is low. The designated treatment hospitals are mainly located in the central areas of districts and counties, and the service scope of hospitals in rural areas of districts and counties cannot be reached under the cost impedance of 0.61h, showing a low accessibility. It is suggested to further optimize the layout and configuration of fever clinics in marginal rural areas and designated hospitals in cities by combining with the resources of primary medical institutions in Hunan Province.
