Update on dengue fever

The Centre for Health Protection (CHP) of the Department of Health today (April 25) reported the latest number of dengue fever (DF) cases, and urged the public to maintain strict environmental hygiene, mosquito control and personal protective measures both locally and during travel.

From April 17 to yesterday (April 24), the CHP recorded one imported DF case. The patient had travelled to Indonesia during the incubation period.

As of yesterday, 14 imported DF cases have been recorded so far this year. A total of 161 cases of DF were recorded in 2024, including 156 imported and five local cases. In 2023, 62 imported cases of DF were recorded.

According to the World Health Organization (WHO), the global incidence of DF has markedly increased over the past two decades, posing a substantial public health challenge. In 2023, ongoing transmissions, combined with an unexpected spike in DF cases, resulted in over 6.5 million cases and more than 7 300 dengue-related deaths reported in over 80 countries/territories. In 2024, the WHO recorded over 14 million cases, which was a record number.

Detailed information on the latest DF situation in Hong Kong, as well as neighbouring and overseas countries and areas, has been uploaded to the CHPwebsite.

Members of the public returning from areas affected by DF should apply insect repellent for 14 days upon arrival in Hong Kong. If feeling unwell, seek medical advice promptly and provide travel details to a doctor.

The public should take heed of the following advice on mosquito control:

  • Thoroughly check all gully traps, roof gutters, surface channels and drains to prevent blockage;
  • Scrub and clean drains and surface channels with an alkaline detergent compound at least once a week to remove any deposited mosquito eggs;
  • Properly dispose of refuse, such as soft drink cans, empty bottles and boxes, in covered litter containers;
  • Completely change the water of flowers and plants at least once a week. The use of saucers should be avoided if possible;
  • Level irregular ground surfaces before the rainy season;
  • Avoid staying in shrubby areas; and
  • Take personal protective measures such as wearing light-coloured long-sleeved clothes and trousers, and apply insect repellent containing DEET to clothing or uncovered areas of the body when doing outdoor activities.
  • ​DEET-containing insect repellents are effective and the public should take heed of the tips below:

  • Read the label instructions carefully first;
  • Apply right before entering an area with risk of mosquito bites;
  • Apply on exposed skin and clothing;
  • Use DEET of up to 30 per cent for pregnant women and up to 10 per cent for children*;
  • Apply sunscreen first, then insect repellent; and
  • Reapply only when needed and follow the instructions.
  • * For children who travel to countries or areas where mosquito-borne diseases are endemic or epidemic and where exposure is likely, those aged 2 months or above can use DEET-containing insect repellents with a DEET concentration of up to 30 per cent.

    The public should call 1823 in case of mosquito problems and may visit the following pages for more information: the DF page of theCHPand theTravel Health Service, the latestTravel Health News,tips for using insect repellents, and the CHPFacebook PageandYouTube Channel.

    Persons in custody participate in Christmas activities

    The Correctional Services Department has arranged for persons in custody (PICs) to attend activities during the Christmas festive period.

    The Bishop of the Catholic Diocese of Hong Kong, Cardinal Stephen Chow, accompanied by the Deputy Commissioner of Correctional Services (Operations and Strategic Development), Mr Leung Ka-lun, visited Stanley Prison and presided at a Christmas mass today (December 25) to share his faith and Christmas blessings with PICs. He also paid a visit to patients in the institution hospital and conveyed his sympathy and support to them.

    Moreover, the Archbishop of Hong Kong, the Most Reverend Andrew Chan, presided at a Christmas service in Pak Sha Wan Correctional Institution on December 22 to preach and share religious messages with PICs, whilst extending his care and good wishes.

    Through the Correctional Services Chaplain, voluntary chaplains and visitors from religious organisations, a variety of spiritual support services are offered to PICs who wish to participate regardless of their religious affiliation. The services include visits, teaching, counselling, and religious and recreational activities.
