基孔肯雅热（Chikungunya fever），又译为契昆根亚热或屈公热，于1952年被发现。此病像登革热一样由蚊传播，主要传播媒介为白线斑蚊。人类被带有基孔肯雅热病毒的蚊子叮咬后，便会患上基孔肯雅热。患者会持续发高烧、脱水和严重出疹。「Chikungunya」源自非洲斯瓦希里语，意指「弯腰」，因病人会关节肿大痛楚，不得不弯腰行走。目前世上还未有防治此症的疫苗或药，治疗以减轻症状为目的。大多数患者可以完全痊愈，关节痛持续数天至数周后就会消失，但有些人的关节痛或会持续更长时间。此病的严重并发症不常见，但老人有可能因此病致死。

Chikungunya (Makonde for "that which bends up") is an infection caused by the chikungunya virus. The disease features the sudden onset of fever two to four days after exposure. The fever usually lasts two to seven days, while accompanying joint pains typically last weeks or months but sometimes years. The mortality rate is a little less than 1 in 1,000; the elderly or those with underlying chronic medical problems are most likely to have severe complications.
