18th June 2024 – (Hong Kong) The Centre for Health Protection (CHP) of the Department of Health (DH) is currently investigating a probable case of locally acquired dengue fever (DF) in Hong Kong. The patient, a 54-year-old female with underlying health conditions, developed a fever and retro-orbital pain since 6th June. Seeking medical attention, she consulted a private doctor on June 9 and subsequently visited the accident and emergency department of Tin Shui Wai Hospital on 11th June. Upon admission on the same day, she was transferred to Pok Oi Hospital on June 14 for further treatment. Thankfully, her condition has stabilized, and laboratory testing confirmed the presence of the dengue virus in her blood sample.

Initial inquiries have revealed that the patient resides in Tin Shui (1) Estate in Tin Shui Wai. Given her limited travel outside of Hong Kong during the incubation period, health authorities suspect that this is a probable locally acquired case. Currently, her close contact at home remains asymptomatic but is under medical surveillance as a precautionary measure. As of now, no epidemiological link has been established between this case and any previously recorded instances of dengue fever in Hong Kong.

In response to this development, the DH is working closely with the Food and Environmental Hygiene Department (FEHD) to assess and prevent any potential spread of infection. The FEHD is actively conducting ongoing vector investigations, surveillance, and control measures. Meanwhile, the CHP continues to conduct epidemiological investigations to gather more information about the case.

Health officers from the CHP have inspected the patient’s residence and will conduct field investigations among neighbouring residents through questionnaire surveys. This proactive approach aims to identify any possible sources of the infection and prevent its further transmission.

Individuals who have visited Tin Shui (1) Estate in Tin Shui Wai and are experiencing symptoms associated with dengue fever are urged to contact the CHP’s hotline (2125 2374), which will be operational starting from 19th June on weekdays (excluding public holidays) from 9am to 5pm. The hotline will provide guidance regarding laboratory investigations or appropriate referrals. Additionally, the CHP, in collaboration with the FEHD, will hold a health talk at 6pm tomorrow in the Tin Shui Community Centre. During this event, the CHP will offer free DF antibody tests to individuals in the district displaying relevant symptoms.

To ensure timely dissemination of information, the CHP will issue letters to local doctors and hospitals, providing them with updates on the latest situation.

This marks the second locally acquired case of dengue fever recorded in Hong Kong this year, alongside 26 imported cases as of 13th June. The CHP spokesperson emphasized that, in addition to general preventive measures, individuals returning from areas affected by dengue fever should apply insect repellent for 14 days upon arrival in Hong Kong. If any symptoms arise, it is crucial to seek prompt medical advice and provide detailed travel information to healthcare professionals.
