Government completes review of report on investigation into aircraft communication loss incident
The Civil Aviation Department (CAD) said today (August 14) that the Government has received and completed the review of the full investigation report submitted by Cathay Pacific Airways (CPA) in regard to an incident on July 4, in which a CPA flight from Hong Kong to London's Heathrow experienced a loss of communication with the local air traffic control unit during its flight.
The report indicated that the aircraft's communication equipment operated normally. The incident involved the incorrect selection of radio frequency by the concerned flight crew due to a mistaken response to air traffic controllers' instructions for another flight, and the flight crew did not subsequently realise the loss of communication.
After the incident, CPA has implemented a host of improvement measures, including enhancing the operational and monitoring procedures for the flight crew regarding the communication system, and reminding the flight crew to be more vigilant at all times.
CAD expressed serious concern over the communication loss incident and has instructed CPA to robustly follow up on the relevant improvement measures, including providing additional training and assessment for the concerned flight crew. CAD reiterated the importance of maintaining good communications between the flight crew and air traffic controllers at all times to ensure aviation safety. CAD has also instructed CPA to enhance the reporting mechanism on aviation safety incidents. CPA implemented the related improvement measures in mid-July and CAD will continue to closely monitor the effectiveness of the measures implemented by CPA.
Update on mosquito-borne diseases, dengue fever and chikungunya fever
The Centre for Health Protection (CHP) of the Department of Health today (August 14) announced the latest situation regarding dengue fever (DF) and chikungunya fever (CF). High temperatures and rainfall in summer are favourable for mosquito breeding, members of the public are reminded to take appropriate measures to prevent mosquito bites and mosquito breeding, both in Hong Kong and when travelling to areas affected by mosquito-borne diseases, in order to prevent mosquito-borne diseases.

Dengue fever
----------------
From August 7 to yesterday (August 13), the CHP recorded one imported DF case. The patient had travelled to Malaysia during the incubation period.
Hong Kong has recorded 28 DF cases so far this year, comprising 26 imported cases and two local cases. A total of 59 DF cases were recorded last year (2025), all of which were imported cases. In 2024, 161 DF cases were recorded, comprising 156 imported cases and five local cases.
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 2024, the WHO recorded over 14 million DF cases, which was a record number. In 2025, over five million cases and over 4 000 DF-related deaths were reported in over 90 countries/territories. From January to June 2026, around 1.6 million cases and over 700 DF-related deaths have been reported in 89 countries/territories. Some Asian countries (including Sri Lanka and Cambodia) are experiencing large outbreaks this year, with figures reaching record highs in recent years.
DF has been prevalent in many neighbouring tourist destinations all along. So far this year, Indonesia, Sri Lanka and Vietnam each recorded over 70 000 cases; Cambodia and Malaysia each recorded over 40 000 cases; India recorded over 30 000 cases; and Singapore recorded over 1 900 cases. Meanwhile, according to the Guangdong Provincial Disease Control and Prevention Administration, Guangdong Province has recorded over 3 500 local cases in 2025. In 2026, as of June 30, Guangdong Province has recorded 30 local cases.
Detailed information on the latest DF situation in Hong Kong, as well as neighbouring and overseas countries and areas, has been uploaded to the CHP's website.
Chikungunya fever
-----------------------
From August 7 to yesterday, no new cases of CF had been recorded. Hong Kong has recorded two confirmed CF cases so far this year, both of which were imported cases. Hong Kong recorded a total of 82 confirmed CF cases last year. Among them, 11 were local cases and the rest were imported cases.
According to the WHO, a total of 502 264 CF cases and 186 CF-related deaths were reported in 41 countries/territories last year. Cases were reported in the Americas, Africa, Asia and Europe. According to the Guangdong Provincial Disease Control and Prevention Administration, in 2026, as of June 30, Guangdong Province has recorded 76 local cases.
Preventive measures to be taken by the public
----------------------------------------------------
The CHP reminds members of the public to maintain good environmental hygiene, and to take appropriate measures to prevent mosquito bites and mosquito breeding, both in Hong Kong and when travelling to areas affected by mosquito-borne diseases, in order to prevent mosquito-borne diseases. Mosquito-borne diseases such as DF and CF are endemic in various countries worldwide. The risk of importation persists. Members of the public should check the situation at their destinations before travelling abroad, especially when travelling to Southeast Asian countries. Additionally, whether travelling or not, members of the public should use DEET-containing insect repellents or other effective active ingredients properly to prevent mosquito bites, but the following precautions should be taken when using them:
- read the label instructions carefully first;
- apply right before entering an area with a 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 (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);
- apply sunscreen first, then insect repellent;
- reapply only when needed and follow the instructions; and
- in addition to DEET, there are other insect repellents available on the market containing different active ingredients, such as IR3535 and picaridin. When using any insect repellent, the public should follow the usage instructions and precautions on the product label.
The Food and Environmental Hygiene Department (FEHD) appeals to members of the public to continue to stay alert and work together to carry out mosquito prevention and control measures early, including inspecting their homes and surroundings to remove potential breeding grounds, changing water in vases and scrubbing their inner surfaces, removing water in saucers under potted plants at least once a week, and properly disposing of containers such as empty cans and lunch boxes. The FEHD also advises members of the public and property management agencies to keep drains free of blockage and level all defective ground surfaces to prevent the accumulation of water. They should also scrub all drains and surface sewers with an alkaline detergent at least once a week to remove any mosquito eggs.
The public should call 1823 in case of mosquito problems, and may visit the following pages for more information: the CF page of the CHP and the Travel Health Service, the latest Travel Health News, tips for using insect repellents, and the CHP Facebook Page, Instagram Account and YouTube Channel, and also the Mosquito Prevention and Control dedicated page of the FEHD.
