Chikungunya, which can disable victims for years, is spreading rapidly, including in China, France and other places that have not seen major outbreaks before.
A mosquito-borne virus that can leave infected people debilitated for years is spreading to more regions of the world, as climate change creates new habitats for the insects that carry it.
More than 240,000 cases of the virus, chikungunya, have been reported around the world so far this year, including 200,000 cases in Latin America and 8,000 in China. Chinese authorities have launched an urgent effort to try to stifle the virus with public health measures that evoke the response to Covid-19.
