Travelers to China Urged to Heed US Travel Warning Over Chikungunya Outbreak

Travelers to China, particularly Guangdong province, are being strongly advised to take note of a recent travel advisory issued by the U.S. Centers for Disease Control and Prevention (CDC) due to a significant chikungunya outbreak. The Level 2 "Practice Enhanced Precautions" alert highlights the growing concern over the mosquito-borne virus in the region and underscores the need for travelers to take serious preventative measures. 

CDC Raises Alert Amidst Significant Outbreak:

The CDC's decision to issue a travel warning comes as Guangdong province experiences its largest documented chikungunya outbreak. Thousands of cases have been reported, with the city of Foshan being the epicenter. Unusually heavy rains and high temperatures have created ideal breeding conditions for the Aedes aegypti and Aedes albopictus mosquitoes, the primary vectors for transmitting the virus.

Understanding Chikungunya:

Chikungunya is a viral disease characterized by a sudden onset of high fever and severe joint pain. Other symptoms can include headache, muscle pain, and a rash. While most people recover within a week, the joint pain can be debilitating and persist for months or even years in some individuals. There is no specific cure for chikungunya, and treatment focuses on relieving symptoms.

Key Recommendations for Individuals Traveling to Affected Areas:

The CDC's travel advisory provides crucial guidance for individuals traveling to Guangdong province:

• Practice Enhanced Mosquito Bite Prevention: This is the most critical step in avoiding chikungunya. Travelers should:
• Use EPA-registered insect repellents: Apply repellents containing DEET, picaridin, IR3535, oil of lemon eucalyptus (OLE), para-menthane-diol (PMD), or 2-undecanone according to product instructions.
• Wear protective clothing: Opt for long-sleeved shirts, long pants, socks, and shoes to minimize exposed skin, especially during peak mosquito activity times (dawn and dusk).
• Stay in air-conditioned or screened-in accommodations: These environments offer a barrier against mosquitoes.
• Use mosquito nets: If your accommodation is not well-screened or air-conditioned, sleep under a mosquito net.
• Consider Chikungunya Vaccination: Two vaccines for chikungunya are now approved in the United States for eligible individuals. Residents traveling to affected areas should consult their doctor to discuss whether vaccination is appropriate for them, considering their travel plans and health history.

Returning Travelers Should Be Vigilant:

Travelers returning from Guangdong province or other areas with chikungunya outbreaks should monitor themselves for symptoms for up to two weeks after their return. If they develop fever, joint pain, or other symptoms consistent with chikungunya, they should seek medical attention immediately and inform their doctor about their recent travel history. This will help healthcare professionals make an accurate diagnosis and take appropriate measures to prevent potential further spread.

Health authorities are echoing the CDC's recommendations and urging travelers to prioritize mosquito bite prevention both during travel and in their daily lives at home. Eliminating mosquito breeding sites around homes and workplaces remains a crucial step in preventing all mosquito-borne diseases.

By staying informed and taking proactive steps, Travelers can protect themselves and contribute to preventing the introduction and spread of chikungunya within our community. If you have any concerns or require further information, please consult with your healthcare provider or local health authorities.
