Since Chikungunya was listed as a notifiable infectious disease by the Taiwan Centers for Disease Control (TCDC) in October 2007, a few travel-related and locally acquired cases have been reported most years.
As of April 25, 2025, the TCDC reports 11 Chikungunya cases this year, indicating a potential increase over last year's total of 20 cases.
And may approach 2019's record when 116 total cases were confirmed.
Previously, to identify infectious travelers, fever screening was conducted at the Taiwan Taoyuan International Airport.
The TCDC states that Chikungunya fever is rarely fatal; however, some patients may experience severe joint pain for several weeks, months, or even years.
In the Asia Region, Chikungunya outbreaks have been recorded as early as 1824 in India.
As of April 25, 2025, the World Health Organization reports that Chikungunya transmission has occurred in approximately 110 countries, many of which are in the Americas, including Argentina and Brazil.
From a health perspective, this mosquito-transmitted disease can be prevented with U.S. Food and Drug Administration-approved vaccines, which are commercially available at travel clinics and pharmacies in the United States.
