The US Centers for Disease Control and Prevention (CDC) recently confirmed that two Taiwanese tourists contracted chikungunya fever after visiting Indonesia last month.
According to the CDC, the couple visited Bali in December and the wife developed muscle pains and a fever on 18 December. She was initially diagnosed as having dengue fever but on 21 December was confirmed as having chikungunya virus.
The husband developed a fever on 15 December and was diagnosed with flu, said the CDC, but was confirmed to have chikungunya on 29 December.
According to the CDC, Taiwan health authorities have been cleaning up mosquito breeding grounds in areas the couple visited and will continue such actions throughout January. The CDC has urged caution on visits to Indonesia, warning that the October to April rainy season is the peak period for mosquito breeding there.
