This year, Latvia has reported three confirmed cases of the Chikungunya virus, all associated with travel to the Seychelles. According to the Centre for Disease Prevention and Control (SPKC), two of these cases occurred within the same family, while the third case is not epidemiologically linked to the others. All three patients had traveled to the Seychelles during their virus incubation period, highlighting potential risks of tropical diseases for travelers returning to Latvia.

Since November 2025, ten European countries have reported over 70 cases of Chikungunya virus among travelers returning from the Seychelles, indicating a significant increase compared to previous months in 2025. This surge signals a concerning trend as the virus appears to be more prevalent on the islands. SPKC experts stress the importance of vigilance and preventive measures for travelers to the Seychelles, given the uptick in confirmed cases.

Chikungunya virus is primarily transmitted by Aedes mosquitoes, which are commonly found in tropical and subtropical regions. While the risk of local transmission in continental Europe is currently deemed low due to winter conditions that are unfavorable for Aedes mosquito activity, continual monitoring is essential as travel patterns may evolve, and the potential for outbreaks persists.
