Prevent Chikungunya Fever: Mosquito Alert
The Robert Dan Health Education Centre, CUHK alerts the CHHK community to a significant rise in Chikungunya fever cases in neighboring regions, as reported by the Centre for Health Protection (CHP).
Chikungunya fever, prevalent in over 110 countries including a recent outbreak of 478 cases in Shunde, Guangdong as of July 15, 2025, is a mosquito-borne viral disease transmitted primarily by the Aedes albopictus mosquito, commonly found in Hong Kong, increasing the risk of imported cases locally, especially during summer due to heightened mosquito activity and travel. Symptoms typically appear 2-12 days after infection and include sudden high fever, severe joint pain, rash, and fatigue; while severe complications affecting the eyes, heart, or nerves are rare, they can occur in newborns, older adults, or those with underlying health conditions.
To protect yourself and the university community, proactively prevent mosquito bites by using DEET insect repellent and wearing long-sleeved clothing, particularly during the day when the Aedes mosquito is most active, and eliminate stagnant water breeding sites. Additionally, continue using repellent for 14 days after returning from affected areas and seek prompt medical attention, informing healthcare providers of any travel history, if you experience symptoms like sudden fever, joint pain, or muscle aches.
