Two Measles Cases Linked in Hong Kong; Vaccination Urged for Prevention

CHP investigates two epidemiologically linked measles infection cases

The Centre for Health Protection (CHP) of the Department of Health (DH) today (June 25) is investigating two cases of measles infection that are epidemiologically linked and reminded the public that vaccination is the most effective way to prevent measles.

The two cases are family members living together. The first case involves a six-month-old baby boy. He presented with fever on June 21, and developed cough, runny nose and skin rash the following day. He was brought to the Accident and Emergency Department of Kwong Wah Hospital on June 23 and was admitted for treatment. His respiratory specimen sample tested positive for the measles virus upon nucleic acid testing.

During contact tracing, the CHP found that the boy's 29-year-old father also presented symptoms of measles, including fever and cough, on June 20 and developed skin rash on June 23. The CHP arranged the patient to attend the Accident and Emergency Department of Kwong Wah Hospital for isolation and testing on June 24. His respiratory specimen sample tested positive for the measles virus upon nucleic acid testing.

Both patients remain hospitalised for isolation and treatment and are in stable condition.

An epidemiological investigation revealed that the baby boy has not yet reach the age to receive the first dose of the measles vaccine, while his father was uncertain whether he had received measles vaccination. One of their household contacts also presented relevant symptoms earlier and has recovered now. Testing is being arranged for this household contact.

The CHP continues to investigate the cases to identify potential sources of infection and high-risk exposure. Initial investigation revealed that no epidemiological linkages have been established between these two cases and other confirmed cases previously recorded in Hong Kong.

"The incubation period of measles (i.e. the time from infection to onset of illness) is seven to 21 days. Symptoms include fever, skin rash, cough, runny nose and red eyes. When such symptoms appear, people should wear surgical masks, stay home from work or school, avoid crowded places and contact with unvaccinated people, especially those with weak immune systems, pregnant women and children under 1 year old. Those who suspect they are infected should consult their doctors as soon as possible and inform healthcare workers of their history of exposure to measles," the Controller of the CHP, Dr Edwin Tsui, said.

"Under the Hong Kong Childhood Immunisation Programme, the overall immunisation coverage in Hong Kong has been maintained at a very high level through the immunisation services provided by the DH's Maternal and Child Health Centres and School Immunisation Teams. As evidenced by the findings on vaccination coverage of primary school students and the territory-wide immunisation surveys conducted regularly by the DH, the two-dose measles vaccination coverage has remained consistently high, well above 95 per cent, and the local seroprevalence rates of measles virus antibodies reflect that most people in Hong Kong are immune to measles. However, Hong Kong, as a city with a high volume of international travel, still faces the potential risk of importation of the measles virus and its further spread in the local community. Hence, a small number of people who have not completed a measles vaccination (such as non-local-born people including new immigrants, foreign domestic helpers, overseas employees and people coming to Hong Kong for further studies) are still at risk of being infected and spreading measles to other people who do not have immunity against measles, such as children under 1 year old who have not yet received the first dose of the measles vaccine," he added.

People born before 1967 could be considered to have acquired immunity to measles through natural infection, as measles was endemic in many parts of the world and in Hong Kong at that time. People born in or after 1967 who have not yet completed the two doses of measles vaccination or whose measles vaccination history is unknown, should consult their family doctors as soon as possible to complete the vaccination and ensure adequate protection against measles.

The number of measles cases in some overseas countries remains at a high level this year. The outbreaks in North America (including the United States and Canada), Europe and neighbouring areas (including Vietnam, Cambodia and the Philippines) are ongoing due to the relatively low vaccination rate. Furthermore, an increasing number of measles cases have also been recorded in Japan and Australia this year. For those who plan to travel to measles-endemic areas, they should check their vaccination records and medical history as early as possible. If they have not been diagnosed with measles through laboratory tests and have never received two doses of measles vaccine or are not sure if they have received a measles vaccine, they should consult a doctor at least two weeks prior to their trip for vaccination.

​

Besides being vaccinated against measles, members of the public should take the following measures to prevent infection:

• Maintain good personal and environmental hygiene;

• Maintain good indoor ventilation;

• Keep hands clean and wash hands properly;

• Wash hands when they are dirtied by respiratory secretions, such as after sneezing;

• Cover the nose and mouth while sneezing or coughing and dispose of nasal and mouth discharge properly;

• Clean used toys and furniture properly; and

• Persons with measles should be kept out of school till four days from the appearance of a rash to prevent the spread of the infection to non-immune persons in school.

Government announces updates on follow-up work on Tai Po fire

The three task forces set up by the Government for the fire at Wang Fuk Court in Tai Po - the Task Force on Investigation and Regulation, the Task Force on Emergency Support and Fund-Raising, and the Task Force on Emergency Accommodation Arrangements - are making full efforts to follow up on the support, relief, and investigation work related to the incident. Details are as follows:

Financial and welfare support

---------------------------------

For the Support Fund for Wang Fuk Court in Tai Po, established by the Government, donations received are about $3.4 billion as of noon today (December 13). With the start-up capital of $300 million from the Government, the fund's total has now reached around $3.7 billion. The fund will be used to assist residents in rebuilding their homes and providing long-term and sustained support.

Accommodation support

---------------------------

As of this morning, a total of 1 392 residents have been accommodated, through the co-ordination of the Home and Youth Affairs Bureau, in youth hostels, camps, or hotel rooms. Another 3 163 residents are currently living in transitional housing units provided by the Housing Bureau or units from the Hong Kong Housing Society (HKHS).

In consideration of the extremely urgent situation of the residents affected by the fire incident, a special arrangement of a full rent exemption has been made earlier by the Housing Bureau to provide accommodation support to those affected residents moving into transitional housing or HKHS projects. In other words, if needed, the affected residents can stay for a longer period of time. The Government will continue to support the affected residents in terms of accommodation, and the residents in need do not have to worry about the relevant rental expenses or the duration of stay.

In addition, staff from the operating organisations of transitional housing and HKHS, as well as volunteers have been working around the clock to furnish the units with essential supplies. Taking Eminence Tower in Hung Shui Kiu as an example, each unit is equipped, upon move-in, with furniture and appliances such as bed frames, mattresses, pillows, cooking stoves and water heaters. Daily necessities including toilet paper, slippers and basic cleaning supplies, etc. are also provided. Such efforts are intended to help the affected residents settle in as quickly as possible.

At the same time, a number of organisations have proactively stationed their staff in some projects to provide residents in need with various forms of support, including free medical and legal consultation services. The Government has also set up service stations in 18 projects where more residents have moved in, providing consultation and support services for residents in need, standing together with them.

Relief supplies and donations

---------------------------------

The supplies donation online platform, established by the Government and the information technology sector, continues to operate, facilitating the registration of supplies donations from organisations and the public. The Government has so far received over 1 800 registrations, of which approximately 30 per cent were submitted by organisations, whereas the others were contributed by the public. The various registered donation items include food and beverages, clothing, daily necessities, bedding, and electrical appliances. The Government is actively assessing residents' actual needs through the relevant policy bureau, government departments, and service organisations for the matching of donated supplies in order to distribute appropriate items in phases to places in need. So far, about 19 600 donation items covering various categories have been distributed to different places. The matching and distribution of supplies will continue.

Regulation and inspection work

----------------------------------

The Housing Department today continued to remove the burnt scaffolding on the external walls of Wang Cheong House, Wang Tai House and Wang Sun House. As the environment at scene is narrow and the scaffolding and the protective nets of individual buildings may be subject to more serious damage, for the sake of safety, the Housing Department will conduct assessments with the Police on the timetable of removing the scaffolding of the remaining four affected buildings. In addition, the Independent Checking Unit of the Housing Bureau has also completed the extraction of concrete core samples from the seven affected buildings at Wang Fuk Court today.

The Development Bureau (DEVB) announced on December 11 a new mechanism for sampling and testing scaffold nets for external walls in Hong Kong. The Buildings Department is preparing for the issuance of a new practice note to registered contractors and will meet with the industry next week. The DEVB is moving ahead in full steam the supporting arrangements to ensure that there are sufficient designated laboratories and a suitable site for off-site sampling work.
