Prevent and control mosquito-borne disease, Chikungunya fever

In response to recent cases of Chikungunya fever (CF) recorded in Foshan of Guangdong and Macao, the Centre for Health Protection (CHP) of the Department of Health (DH) said that Guangdong, Hong Kong and Macao have been carrying out joint prevention and control of communicable disease involving the three places in accordance with the well-established liaison and communication mechanism.

Although no confirmed CF cases have been recorded in Hong Kong so far this year, the increase in temperature and rainfall in summer is expected to aggravate mosquito infestation in Hong Kong. Additionally, people travel more frequently during summer holidays, including to regions where mosquito-borne diseases are endemic. Consequently, there is an increased risk of imported cases and local transmission of mosquito-borne diseases, such as CF and dengue fever. Members of the public are advised to take precautionary and personal protection measures against mosquitoes, both locally and when travelling outside Hong Kong.

Information on CF：

The symptoms of CF are similar to those of dengue fever. Patients with CF typically presented with fever and joint pain. Other common symptoms include muscle pain, headache, nausea, fatigue and rash. While most patients recover on their own, in some cases, joint pain may persist for several months or even years. The mortality rate of CF is generally lower than that of dengue fever.
