Japanese encephalitis virus (JEV) is transmitted to humans from pigs or birds by mosquitoes. In this study, the association between urban pig keeping and mosquito vectors was analyzed. A total of 7, 419 mosquitoes were collected overnight in urban households with and without pigs in Can Tho City, Vietnam. The most prevalent vectors were (36%), (24%), and (15%), which were present in all parts of the city. Pigs were associated with increased numbers of . Traps close to pigs had higher numbers of and than traps close to humans. Increased number of persons in the household was associated with increased numbers of . We demonstrate that JEV vector species are present at urban households with and without pigs, and show that keeping pigs in an urban area increase the number of mosquitoes competent as vectors for JEV.
