Which mosquito-borne virus prompted a travel warning from the CDC in Guangdong, China?

The Chikungunya virus is the mosquito-borne virus that prompted a travel warning from the CDC in Guangdong, China. This virus is primarily transmitted by Aedes mosquitoes, which are prevalent in many tropical and subtropical regions. Chikungunya is known for causing symptoms such as fever and severe joint pain, and outbreaks can significantly impact public health and travel safety.

The CDC issues travel warnings to alert travelers to the risk of infection in certain areas, particularly when there is a noted increase in cases. In the case of Chikungunya, the warning would have been based on surveillance data indicating a rise in the number of infections or clusters of cases in a specified area like Guangdong.

Dengue fever, Zika virus, and West Nile virus are also significant mosquito-borne diseases, but the context of this specific alert refers to Chikungunya. Each of these viruses poses its own risks, but the current focus of the travel warning was on Chikungunya's resurgence in that region.
