[Risk Assessment of Malaria in Libo County, Guizhou Province].

Data concerning malaria endemic situation during 2006-2012 and data concerning malaria transmission risk and malaria elimination capacity during 2010-2012 were collected. The results showed that during 2006-2012, malaria in Libo County was predominated by vivax malaria with the transmission vector of Anopheles sinensis, and malaria incidence declined year by year（3.72/10 000, 3.56/10 000, 5.76/10 000, 4.34/10 000, 2.54/10 000, 1.14/10 000, and 0, respectively）.
