Every year, Singapore braces itself for its familiar battle against dengue. But another mosquito-borne virus is quietly gaining ground across the tropics – one carried by the same Aedes mosquitoes that thrive here. Chikungunya, long overshadowed by dengue, is re-emerging with new mutations, more severe symptoms and a worrying ability to spread in urban environments.
Already, Singapore has experienced a spike in chikungunya cases, with 17 reported from the start of the year to Aug 2 – more than double the number for the same period in 2024, said the Communicable Diseases Agency. This follows a recent chikungunya outbreak in Guangdong, China, with cases subsequently reported in Taiwan and Hong Kong.
