Chikungunya often mimics other mosquito-borne diseases such as dengue and Zika, with similar symptoms of joint pain, high fever, and other flu-like symptoms.
The Centers for Disease Control and Prevention has issued Level 2 travel notices for several countries facing heightened chikungunya activity, including China (Guangdong), Bolivia, and islands in the Indian Ocean. While cases are not currently widespread in the United States, experts say the risk of domestic transmission is low. Still, there were 199 travel-related cases in 2024, and 54 cases so far this year.
