An outbreak of chikungunya virus (CHIKV) infection occurred in southwest Bangkok during the 2018 rainy season. The envelope glycoprotein E1 gene sequence of the infecting strain belonged to an East/Central/South African lineage with alanine at residue 226. Mutations in the predicted E1 (K211E) and E2 (V264A) proteins of CHIKV were identified in CHIKV-infected patients and in an Aedes aegypti mosquito. Analysis of the complete genome sequences showed marked differences from the strains causing previous outbreaks in Thailand in 2008-2009 and 2013 but showed similarities to strains from more recent CHIKV outbreaks in South and Southeast Asia.
2018 年雨季，曼谷西南部爆发了基孔肯雅热病毒（CHIKV）感染疫情。感染株的包膜糖蛋白 E1 基因序列属于东/中非/南非谱系，其 226 位残基为丙氨酸。在感染 CHIKV 的患者和埃及伊蚊中鉴定出 CHIKV 中 E1（K211E）和 E2（V264A）蛋白的突变。对完整基因组序列的分析表明，与 2008-2009 年和 2013 年泰国之前的疫情爆发的菌株有明显差异，但与最近南亚和东南亚的 CHIKV 疫情爆发的菌株相似。
