The container breeding mosquito, Aedes aegypti, is recognized as the major global vector of dengue viruses, causing approximately 50 million infections annually.  We previously reported a new community-based mosquito control strategy which resulted in the elimination of Ae. aegypti in 40 of 46 communes in three northern and three central provinces of Vietnam, with only small numbers of larvae detected in the others. During 2007 and 2008, we revisited Nam Dinh and Khanh Hoa provinces in northern and central Vietnam, respectively, to evaluate whether these programs were still being maintained four and a half (in Khanh Hoa) to seven years (in Nam Dinh) after cessation of project activities. We previously have reported the application of a modified sustainability framework to one original project (1998 -- 2000) commune, Xuan Phong. Herein, we compare these results with those from Tho Nghiep commune, Nam Dinh and for Ninh Xuan commune in Khanh Hoa province for which locally-driven activities commenced in 2002 and 2003, respectively. To gauge program efficacy, we compared these data with that for four National Dengue Control Program communes where some control activities had occurred and against one where few activities were carried out. All three communes post-project were rated as well sustained with recurrent annual direct and indirect costs of $0.54 -- $1.71 international dollars per person.
