CDC Issues Travel Advisory for China
The U.S. Centers for Disease Control and Prevention (CDC) has issued a travel warning for Americans planning to visit China due to a significant outbreak of the chikungunya virus. The advisory urges travelers to take “enhanced precautions” as the mosquito-borne illness rapidly spreads, particularly in Guangdong province, with Foshan city being the most affected area. Since June 2025, over 7,000 cases have been confirmed in Foshan alone, according to Chinese health officials.
Understanding Chikungunya Virus Symptoms
Chikungunya virus infection typically presents symptoms 3–7 days after a mosquito bite. The CDC highlights that common symptoms include fever and joint pain, while others may experience headache, muscle pain, joint swelling, or rash. Although most individuals recover within a week, some may suffer from severe joint pain lasting months or even years. Those at higher risk for severe disease include newborns infected around birth, older adults over 65, and individuals with pre-existing conditions like diabetes or heart disease. While fatalities are rare, there is no specific treatment for chikungunya.
Preventive Measures in Foshan
In response to the outbreak, Foshan has implemented various measures to control mosquito populations. These include deploying drones to locate breeding sites, using mosquito repellent on residents before entering buildings, and introducing mosquito-eating fish into ponds. Such efforts aim to reduce the spread of the virus and protect public health.
Global Impact and Additional Outbreaks
The European Centre for Disease Prevention and Control reported approximately 240,000 global chikungunya cases across 16 countries and territories by July, linked to 90 deaths. Besides China, outbreaks have been noted in Bolivia, Kenya, and Sri Lanka. Travelers to Brazil, Colombia, India, Mexico, Nigeria, Pakistan, the Philippines, and Thailand also face increased exposure risks.
CDC’s Recommendations for Travelers
To minimize risk while traveling to affected areas, the CDC advises using insect repellent, wearing long-sleeved clothing, and staying in air-conditioned or screened accommodations. Vaccination is recommended for those visiting regions with active outbreaks; currently, two chikungunya vaccines are approved in the U.S. The CDC emphasizes seeking immediate medical attention if symptoms such as fever or joint pain develop during or after travel.
