New cases of Chikungunya fever in Foshan, a city in south China's Guangdong Province, have continued to decline thanks to a series of targeted prevention measures, municipal authorities said on Saturday.

For the past five days, the city has recorded fewer than 200 new cases each day, signaling early containment success, Wen Xi, the city's vice mayor, told a press conference.

No severe cases or fatalities have been reported to date, and more than 90 percent of all cases have recovered, Wen noted.

Recent efforts have focused on patient treatment, mosquito control and environmental cleanup. Specific measures include the targeted elimination of mosquito breeding grounds, the drainage of stagnant water and the extermination of adult mosquitoes. Disinfection work has been carried out in villages and neighborhoods that have reported high case numbers.

Despite the progress, authorities warn that challenges remain. Heavy rainfall during the annual flood season, coupled with typhoons, can boost mosquito activity and increase the risk of Chikungunya transmission.

"We will continue to promote public health campaigns, remove breeding sites and maintain strong mosquito control measures to consolidate the results achieved so far," Wen said.

Chikungunya fever is an acute infectious disease caused by the Chikungunya virus, which presents in clinical symptoms such as fever, rashes and joint pains. The virus is transmitted to humans through bites from infected mosquitoes.
