Abstract

Objective To explore the relationship between land cover and the risk of hemorrhagic fever with renal syndrome (HFRS). Methods Annual HFRS cases and landcover in epidemic areas of Gansu Province during January 1, 2012 and December 31, 2022 were collected and analyzed. Poisson regression model was applied to assess the relative risk of main land cover, landcover percentage and the risk of HFRS, and restricted cubic spline was applied to determine the corresponding exposure-response relationship. Results The HFRS risk in areas with main land cover of grassland was 2.781 (95% CI: 2.336-3.310, P < 0.01) times in comparison with which in cropland areas, and the risk of forests and shrub areas was lower than which in cropland areas, with the coresponding RRs were 0.455(95% CI: 0.319-0.648, P < 0.01) and 0.130(95% CI: 0.041-0.401, P < 0.01). And the risk of HFRS increased with the percentages of grassland increasing, decreased with the percentage of cropland and barren increasing, and showed an inverse V-shaped relationship with the percentage of forests and shrub. Conclusions Land cover is associated with the risk of HFRS. The formulation of prevention and control strategies and measures for HFRS should consider land cover and its changes to reduce the epidemic risk of HFRS.
