Climate variability and HFRS in China.

The transmission of hemorrhagic fever with renal syndrome (HFRS) is influenced by climatic variables. Few studies, however, have examined the quantitative relationship between climate variation and HFRS transmission. Zhang et al. (p. 915) examined the potential impact of climate variability on HFRS transmission and developed climate-based forecasting models for HFRS in northeastern China using data on monthly counts of reported HFRS cases during 1997-2007 obtained from the Inner Mongolia Center for Disease Control and Prevention and climate data from the Chinese Bureau of Meteorology. Cross-correlation and Poisson regression analyses showed that rainfall, land surface temperature, relative humidity, and the multivariate El Nino Southern Oscillation index were significantly associated with monthly HFRS cases with lags of (3-5) months. The authors conclude that climate variability could play a significant role in HFRS transmission in northeastern China.
