On July 15, Guangdong's Foshan City reported a local outbreak of chikungunya fever triggered by imported cases. At the time of the announcement, a cumulative total of 478 confirmed cases had been reported across Shunde District, all of which were mild.
Chikungunya fever is an acute infectious disease caused by the chikungunya virus and is transmitted through the bites of Aedes mosquitoes, commonly known as Asian tiger mosquitoes. People of all ages are susceptible to infection and subsequent illness.
Compared to dengue fever, chikungunya fever has a shorter febrile period, but the joint pain is more pronounced and lasts longer.
After infection, symptoms typically appear within 3 to 7 days. The main manifestations include fever, significant joint pain, and rash. Patients may also frequently experience muscle pain, headaches, nausea, and fatigue. The majority of patients have mild cases, and most can recover within about a week. Severe and fatal cases are relatively rare.
Experts from the Guangdong Provincial Center for Disease Control and Prevention stated that there are currently no specific antiviral drugs or vaccines available for chikungunya fever. Therefore, the key to protection lies in mosquito control and the prevention of mosquito bites.
If symptoms such as fever, joint pain, or rash occur, individuals are advised to seek medical attention promptly at a reputable medical institution. Early symptomatic treatment can effectively alleviate discomfort.
In terms of daily prevention, disease control experts recommend the following measures:
1. Eliminate standing water
Regularly check and empty any containers that can hold water, such as pots and pans turned upside down. For indoor potted plants with water, change the water every 3 to 5 days. Cover water storage containers to prevent mosquitoes from breeding.
2. Actively eliminate mosquitoes
Keep mosquito coils, electric mosquito swatters, and mosquito repellent sprays on hand. Clean hard-to-reach areas where mosquitoes may hide. Preventing mosquito bites can help stop the transmission of such viruses.
3. Ensure personal protection
When going out, wear light-colored long-sleeved shirts and long pants. Avoid lingering in shaded areas under trees or in grassy patches outdoors. Install screen doors and windows at home and use mosquito nets while sleeping.
