The US Centers for Disease Control and Prevention (CDC) has issued a Level 2 travel advisory for Guangdong Province, China, following a major outbreak of chikungunya virus infections. The advisory urges travelers to “practice enhanced precautions” when visiting the region.
According to the CDC, this outbreak is the largest ever recorded in China, with over 8,000 cases reported since June 2025. The epicenter of the outbreak is Foshan City, located in southern Guangdong.
What the CDC Recommends for Travelers
The CDC is advising travelers to take the following steps:
- Use mosquito repellent and wear long-sleeved clothing
- Stay in air-conditioned or well-screened accommodations
- Pregnant travelers should reconsider travel plans due to higher risks
The CDC emphasized:
“Vaccination against chikungunya should generally be deferred until after delivery. However, when the risk of infection is high and exposure cannot be avoided, pregnant travelers should consult with their healthcare provider.”
Why the Advisory Was Issued
The outbreak has raised concerns among international health officials because of its rapid spread and comparisons to early COVID-era containment measures in China.
Chikungunya is transmitted by mosquito bites and typically causes fever, joint pain, headache, and rash. Most patients recover within a week, but joint pain can persist for months or even years.
