DH following up on cluster of infections of disease of temporarily unknown cause in Democratic Republic of Congo
Following reports of a cluster of infections of a disease of temporarily unknown cause in the Democratic Republic of Congo (DRC), the Centre for Health Protection (CHP) of the Department of Health (DH) said today (December 5) that it had taken the initiative to seek further information from the World Health Organization (WHO), the Africa Centres for Disease Control and Prevention and the DRC health authorities.
According to the information announced by the DRC health authorities, since late October, 79 deaths due to a disease of still unknown cause have been recorded in a district in Kwango province, and more than 300 people have been infected. Most of the patients were aged above 15 and suffered from fever, headache, runny nose, cough, breathing difficulty and anaemia.
"Under the current mechanism, Hong Kong has been equipped with the ability to detect infections of unknown cause and emerging infectious diseases at boundary control points and hospitals. On the immigration level, the DH has been conducting temperature screening for arrivals at all boundary control points. Those who are found to have a fever will be assessed and transferred to public hospitals for medical examination as appropriate. Upon noticing that a disease of temporarily unknown cause in the DRC, the DH has immediately tried to collect the latest information from various channels to conduct risk assessment and formulate appropriate preventive and control measures," a spokesman for the CHP said.
There are currently no direct flights between the DRC and Hong Kong. The CHP has learned from the trade that travellers coming to Hong Kong from the DRC may generally choose transit hubs in Africa to Hong Kong, including Johannesburg in South Africa and Addis Ababa in Ethiopia. In light of the disease of temporarily unknown cause in the DRC, the CHP has, as a precautionary measure, immediately stepped up health screenings at the airport for passengers on all flights arriving in Hong Kong from the above-mentioned transit hubs. Port Health staff have been arranged to carry out temperature checks for travellers at the relevant flight gates, conduct medical assessments for symptomatic travellers and refer suspected cases of infections with public health significance to hospitals for medical examination.
"Members of the public who plan to go to the DRC should be vigilant and pay attention to personal and environmental hygiene at all times, and avoid visiting crowded places and having contact with sick persons. Upon returning to Hong Kong, one should seek medical treatment as soon as possible if they feel unwell and take the initiative to inform their doctors of their relevant travel history," he added.
Since October, the DH has not received any reports of people or travellers arriving in Hong Kong from the DRC suffering from unknown diseases.
"The DH will continue to closely monitor the situation in the DRC and WHO's related information, and take appropriate preventive and control measures based on risk assessment to protect public health," the spokesman said.
Pilot Scheme on Wading Line System to cope with flooding at low-lying road sections (with photos/video)
In view of the increased chance of flooding at low-lying road sections caused by heavy rain under extreme weather, the Government will launch the Pilot Scheme on Wading Line System at five low-lying road sections with higher risk to monitor the flooding situation in real time, to facilitate effective mobilisation and collaboration of relevant government departments to tackle flooding as early as possible, and alert drivers of flooding on the road ahead, thereby reducing the possibility of vehicles stalling due to damage by flooding.
A Government spokesman said today (April 11) that the five pilot road sections are located at Chai Wan Road, Lung Cheung Road, Tsui Ping Road, Chatham Road North, and Nam Wan Road in Tai Po Market. During the severe rainstorms in September 2023, these locations experienced more serious flooding, causing damage to vehicles and rendering them inoperable.
Warning signs of the system will be placed at low-lying road sections, including a red wavy line and the words "Wading Line" painted on the road surface, with a water meter gauge placed next to it and a sign erected next to the carriageway. When the water level has reached or submerged the wading line, it indicates that the depth of the water at the lowest point of the road ahead has reached 0.3 metre or above.
In addition, the Drainage Services Department (DSD) will install water level sensors called Flood Monitoring Devices at the lowest point of the road sections to collect real-time water level data. When the devices detect that the water level on the road has reached the warning level, the monitoring system will immediately alert relevant government departments. The DSD and the Highways Department (HyD) will promptly deploy emergency response teams to inspect and clear blocked drains to reduce the risk of flooding. When the depth of the water has reached 0.3 metre, there will be temporary traffic guidance on-site to prevent vehicles from entering the flooded road sections. The Transport Department will disseminate information on traffic arrangements accordingly and the Police will assist at scene as necessary.
If vehicles have entered low-lying road sections before temporary traffic guidance is in place, drivers should stop their vehicles before reaching the wading line and avoid entering the flooded area. They should turn on hazard warning lights and follow the on-site directions to leave the temporarily closed road sections.
The Government will monitor the implementation of the pilot scheme, review its effectiveness in due course and optimise it as necessary.
To facilitate the progressive installation of warning signs of the system at the pilot road sections by the HyD, which will begin in late April, temporary traffic arrangements will be implemented in phases at the relevant road sections. The installation is expected to be completed in mid-May.
