Health authorities in China have issued a travel alert for the United States following a concerning rise in cases of the Chikungunya virus, a mosquito-borne disease. The warning urges travellers to take extra precautions to avoid mosquito bites, which can transmit the virus.
What is the Chikungunya Virus?
The Chikungunya virus is spread primarily by Aedes aegypti and Aedes albopictus mosquitoes, the same species responsible for dengue and Zika. Symptoms include high fever, severe joint pain, muscle aches, headaches, and rashes. While rarely fatal, the illness can cause debilitating pain lasting weeks or even months.
Why the Travel Alert?
China's decision to issue the advisory comes as the US reports an unusual spike in Chikungunya infections, particularly in southern states where mosquito populations thrive. Health experts warn that climate change and increased international travel could exacerbate the spread of the disease.
Precautions for Travellers
- Use insect repellent containing DEET, picaridin, or oil of lemon eucalyptus.
- Wear long-sleeved clothing and trousers in high-risk areas.
- Stay in accommodations with air conditioning or mosquito screens.
- Avoid stagnant water, where mosquitoes breed.
Chinese health officials are closely monitoring the situation and have advised returning travellers experiencing symptoms to seek medical attention immediately.
