Overview

• The CDC elevated its Guangdong notice to Level 2, urging travelers to practice enhanced precautions because of chikungunya.
• Guidance includes EPA-registered repellents, long sleeves and pants, staying in screened or air-conditioned lodging, and avoiding standing water.
• The agency recommends vaccination for those traveling to outbreak areas, advising most pregnant travelers to reconsider trips near delivery and generally to defer vaccination unless exposure cannot be avoided after clinical consultation.
• The outbreak is concentrated in Foshan, where authorities have launched aggressive containment measures that observers compare to early COVID-era tactics.
• WHO notes severe, sometimes prolonged joint pain with higher risk for newborns, older adults, and those with underlying conditions, and U.S. data show 46 travel-related cases this year with no local transmission since 2019.
