Co-circulation of dengue virus type 3 genotypes in Vientiane capital, Lao PDR

PLoS One. 2014 Dec 31;9(12):e115569. doi: 10.1371/journal.pone.0115569. eCollection 2014.


During the 2012 epidemic of dengue in Vientiane capital, Lao PDR, a major serotype switch from dengue 1 to 3 was observed. A molecular epidemiology study demonstrated that dengue 3 remained the predominant serotype in 2013, but also revealed the co-circulation of two genotypes, supporting the hypothesis of multiple geographic origins of dengue 3 strains circulating in Vientiane capital.
