Dengue Fever Risk

JAMA. 2011;306(15):1644. doi:10.1001/jama.2011.1486

In regions where dengue fever is endemic, people in areas of low-to-moderate population density who have limited access to tap water are more likely to contract the disease than those in highly populated regions, report researchers from Japan, Vietnam, and the United Kingdom (Schmidt W-P et al. PLoS Med. 2011;8[8]:e1001082).

The investigators analyzed the effect of population density and lack of tap water supply on the risk of dengue fever by linking household data with hospital admission records from a population in south central Vietnam (with about 350 000 people) that experienced 2 dengue epidemics between January 2005 and June 2008.
