Abstract
Chikungunya outbreak in Bueng Kan Province, Thailand, 2013.
Highlights
Based on the genome and the viral envelope E1 sequences, chikungunya virus (CHIKV) is classified into 3 genetic lineages: Asian, West African, and East/Central/South African (ECSA) genotypes (2)
In Thailand, the first report of CHIKV infection occurred in Bangkok in 1958 (3); later, sporadic cases of chikungunya fever occurred in many provinces during 1976–1995 (4)
We report an outbreak of CHIKV infection in the northeastern province of Bueng Kan in 2013
Summary
Based on the genome and the viral envelope E1 sequences, CHIKV is classified into 3 genetic lineages: Asian, West African, and East/Central/South African (ECSA) genotypes (2). In Thailand, the first report of CHIKV infection occurred in Bangkok in 1958 (3); later, sporadic cases of chikungunya fever occurred in many provinces during 1976–1995 (4). All of the CHIKV strains found in Thailand at that time were of the Asian genotype.
