| Summary: | Objective: China has the highest incidence of hemorrhagic fever with renal syndrome (HFRS) worldwide. This study examines the influences of meteorology, air pollution, and their interplay on HFRS cases, aiming to guide prevention and control strategies under varying meteorological conditions. Methods: Data on daily HFRS cases, meteorology, and air pollutants in Hunan, 2012–2021, were collected. The effects of the mixed effects of meteorological and air pollutants on the incidence of HFRS were comprehensively evaluated by constructing a distributed hysteresis linear model (DLNM) and Bayesian nuclear machine regression (BKMR). Results: (1) The results of the DLNM revealed that when the wind speed (WS) = 1.9 m/s, HFRS had the lowest risk of onset (RR = 0.25). The risk of HFRS was highest on day 21 in the high WS group (RR = 1.12). (2) The results of the BKMR showed that, under medium- and low-temperature conditions, relative humidity (RH), sulfur dioxide (SO2), and ozone (O3) had the greatest impact (Posterior inclusion probabilities (PIP) = 1.0). (3) The combined effects of meteorological factors and atmospheric pollutants were positively correlated with the incidence of HFRS under medium and high temperature conditions, while the opposite was true for medium and low temperatures. Conclusion: Meteorological factors and air pollutants have a lag effect on the incidence of HFRS. The combined effects of meteorological factors and air pollutants promote the pathogenesis and spread of HFRS. The higher the level of exposure to other studied factors at moderate and high temperatures, the greater the risk of HFRS. Thus, HFRS should be focused on and precautions should be specified in medium and high temperature environments. |
