Overview

• U.S. health officials now advise travelers to Guangdong to practice enhanced precautions after elevating the chikungunya advisory to Level 2.
• The outbreak is centered in Foshan with several thousand cases reported in southern China, and local reports say Foshan has ended its Level III emergency after daily cases declined.
• CDC guidance emphasizes EPA-registered repellents, long sleeves and pants, and screened or air‑conditioned lodging, with vaccination recommended for most travelers to outbreak areas.
• Pregnant travelers are urged to reconsider trips to affected areas and generally defer vaccination, given the risk of severe illness in newborns if infection occurs near delivery.
• Travel-linked spread continues internationally, with 46 U.S. travel cases reported this year and 73 cases in England from January to June, as newly approved vaccines in the U.S. and U.K. become available to travelers.
