Foshan, Guangdong Province, has reported cases of chikungunya fever, local authorities announced at a press conference held on the afternoon of the 20th. The briefing outlined the virus’s transmission routes, typical symptoms, and key prevention measures to inform the public.
He Jianfeng, deputy director of the Guangdong Provincial Center for Disease Control and Prevention, explained that chikungunya fever is an acute infectious disease caused by the chikungunya virus, primarily spread through bites from Aedes mosquitoes, commonly known as “spotted mosquitoes.”
Typical symptoms start with fever, followed by joint pain—most notably in smaller joints like the wrists, knees, ankles, and finger joints, He noted. A maculopapular rash usually develops 2–3 days later, appearing on the limbs or trunk, and typically fades within 3–5 days. The illness generally lasts 5–7 days, with most patients experiencing mild symptoms. All cases identified in Guangdong so far are mild.
However, certain groups require extra attention: newborns, adults over 65, and individuals with chronic conditions such as hypertension, diabetes, or heart disease are more likely to develop complications if infected. “Anyone with fever, rash, or joint pain should seek immediate medical care at a regular healthcare facility, report their travel history and mosquito bite exposure, and follow treatment guidance,” He emphasized.
Preventing chikungunya hinges on three core actions: eliminating adult mosquitoes, clearing stagnant water, and avoiding bites. Residents can use household mosquito-control products like electric repellents, mosquito coils, and insecticide sprays to kill adult mosquitoes. It’s also critical to remove mosquito breeding sites, including containers for aquatic plants, saucers under flower pots, roof containers with standing water, and any outdoor vessels holding water.
To avoid bites, households should install screen doors and windows, and use bed nets while sleeping. When outdoors, wear light-colored, long-sleeved clothing and apply repellents containing DEET.
He Jianfeng stressed that chikungunya is preventable and controllable, urging the public not to panic. A Foshan official added that since the virus spreads only via mosquito bites—not person-to-person—mosquito control is key to prevention.
Foshan plans to intensify patriotic health campaigns, conduct citywide of mosquito breeding grounds, and work to protect public health. Authorities call on residents to take active steps to reduce mosquito populations and lower transmission risks.
