A fast-spreading mosquito-borne illness is rising across several countries, prompting global health officials to urge extra precautions for travelers. The virus, known for causing high fever and severe joint pain, currently has no antiviral treatment, making prevention the most effective line of defense. Health agencies highlight that countries including Cuba, Bangladesh, Sri Lanka, and parts of China are witnessing a sharp surge in cases.

With hundreds of thousands affected worldwide, experts warn that the disease can lead to prolonged weakness or dangerous complications, especially for older adults. Travelers are encouraged to get vaccinated, use insect repellents, and avoid mosquito-prone areas to reduce risk. Simple safety steps can greatly lower the chance of infection while traveling.
