Epidemiologist warns of Chikungunya fever risk after Shunde outbreak

The Centre for Health Protection (CHP) urges the public to take anti-mosquito measures
and stay vigilant against Chikungunya fever, a mosquito-borne disease, following an outbreak in Shunde, Guangdong, this month.

The World Health Organization reported over 220,000 cases of the disease across 14 countries and regions worldwide as of early June this year, with about 80 resulting in fatalities.

Speaking on a radio program, Senior Medical and Health Officer (Epidemiology) at CHP, Wong Hoi-kei, noted that the authorities have been preparing for the risk of imported cases from Shunde as a precautionary measure.

Wong explained that Aedes albopictus, a mosquito species capable of transmitting Chikungunya fever, is common in Hong Kong.

Imported cases of the disease can lead to local transmission if patients are bitten by mosquitoes during the communicable period, he said, stressing that inadequate mosquito control also poses a risk of outbreaks.

The incubation period for the infection ranges from two to 12 days, with symptoms such as fever, rash, and severe joint pain potentially appearing, he said.

Wong added that treatment primarily focuses on symptom relief, and there is currently no vaccine available.

He reminded the public to take anti-mosquito precautions, especially during humid weather. Passengers returning from areas affected by the disease should apply insect repellent for 14 days upon arrival in Hong Kong.

Additionally, Wong urged the traveler to seek medical attention promptly if they experience any symptoms and to inform their doctor about their recent travel history.
