The Centre for Health Protection announced on Saturday that two individuals had been diagnosed with chikungunya fever.
The first case involves a 69-year-old woman from Kwun Tong District who traveled alone to Zhongshan in Guangdong from late September to early October.
She began experiencing fever and joint pain on October 10 and sought treatment at the Accident and Emergency Department of Kwong Wah Hospital, where she was admitted for care in a mosquito-free environment.
Laboratory tests confirmed the presence of the chikungunya virus in her blood, and she remains in stable condition with no household contacts reported.
The second case involves a 51-year-old man from Wan Chai District who visited Jieyang and Shantou in Guangdong earlier in October.
He developed a fever, followed by joint pain and a rash over the next few days, leading him to seek care at a private hospital’s outpatient clinic.
He was admitted for treatment in a mosquito-free setting, and tests confirmed he was infected with the chikungunya virus.
He is also in stable condition. Four travel companions and one household member, who did not travel, are currently symptom-free but under medical observation.
Health officials determined that both individuals likely contracted the virus during their travels in Guangdong, classifying the cases as imported.
The Centre for Health Protection has notified Guangdong’s health authorities and is continuing its investigation.
These cases bring Hong Kong’s total chikungunya fever cases in 2025 to 31, all of which were acquired abroad.
