- Abstract
This study examined the effect of meteorological factors on the occurrence of hemorrhagic fever with renal syndrome (HFRS) using a generalized additive model with penalized smoothing splines in Jiaonan, China, from 2006 to 2011. The dose-response relationship was first examined, and then the association between daily meteorological variables and HFRS occurrence was investigated according to the dose-response curves. There were two linear segments in the temperature-HFRS relationship curve. When daily temperature was lower than 17 °C, a positive association was found [with excessive risk (ER) for 1 °C increase on the current day being 2.56 %, 95 % confidence interval (CI): 0.36 % to 4.80 %]. An inverse association was found when daily temperature was higher than 17 °C [ER for 1 °C increase on the current day was −12.82 % (95 % CI: −17.51 % to −7.85 %)]. Inverse associations were observed for relative humidity [ER for 1 % increase on lag day 4 was −1.21 % (95 % CI: −1.63 % to −0.79 %)] and rainfall [ER for 1 mm increase on lag day 1 was −2.20 % (95 % CI: −3.56 % to −0.82 %)]. Meteorological factors might be important predictor of HFRS epidemics in Jiaonan County.
