The Centre for Health Protection (CHP) of the Department of Health announced that as of 5 pm today (Sept. 14), one new case of chikungunya fever (CF) had been recorded.
The case involves a 46-year-old female living in Tung Chung. Preliminary investigation revealed that she visited Jiangmen in Guangdong on September 6, during which she was bitten by mosquitoes. She returned to Hong Kong on the same day. She developed a fever, joint pain and a rash from September 11. She went to Jiangmen on the same day and attended a local hospital there before returning to Hong Kong on September 12. She attended Queen Elizabeth Hospital on September 13 and was admitted for treatment in a mosquito-free environment. She is now in stable condition. Her blood sample tested positive for the CF virus upon laboratory testing by the Hospital Authority.
Four people who accompanied the patient to Jiangmen on September 6 and another household contact of her (who did not travel to Jiangmen with her) are currently asymptomatic and under medical surveillance.
Since the patient stayed in Jiangmen during her incubation period, the CHP considered that she was infected during travel. The case was classified as imported. The CHP's epidemiological investigation is ongoing, and it has reported the case to the health authority of Guangdong Province.
So far this year, Hong Kong has recorded a total of 17 confirmed CF cases. All are imported cases. From 2016 to 2019, Hong Kong recorded between one and 11 imported cases annually.
According to information from the Guangdong Provincial Disease Control and Prevention Administration, there were 201 new CF cases in Guangdong during the past week (Sept. 7 to 13), similar to the previous two weeks, which reported 178 cases (August 31 to September 6) and 225 cases (August 24 to 30) respectively. All cases were mild, with no severe or fatal cases reported.
From January to July this year, more than 240,000 cases were recorded in 16 countries/regions worldwide, including about 90 deaths. In Asia, India and Indonesia recorded more than 32,000 and 17,000 cases respectively in 2025. Other regions that have recorded CF cases include the Mainland, Bangladesh and Sri Lanka, etc. Although the situation in Guangdong Province has been under control since late August, with only sporadic new cases reported each day, CF outbreaks continue in many countries worldwide. Members of the public should check the situation of the destinations before travelling abroad.
