Scientific Committee on Vector-borne Diseases releases consensus statement on prevention and control of chikungunya fever
In response to the recent spike in chikungunya fever (CF) cases in multiple regions worldwide, the Scientific Committee on Vector-borne Diseases (SCVBD) under the Centre for Health Protection (CHP) of the Department of Health convened a meeting today (August 4) to review the recent epidemiological data and corresponding prevention and control strategies for CF in Hong Kong. The SCVBD noted that the Government has already implemented a series of preventive measures against CF.
The consensus statement by the SCVBD provided a risk assessment for Hong Kong and recommended ongoing measures for the Government to mitigate the risk of CF imported cases and potential local transmission.
Risk assessment
CF is caused by the chikungunya virus and is mainly transmitted by Aedes mosquitoes. According to the World Health Organization (WHO), CF cases have been recorded in more than 110 countries/regions. As of early June this year, over 220 000 cases had been reported in 14 countries/regions worldwide. Of these cases, about 80 were fatal. CF is endemic in parts of Asia, with concurrent circulation alongside dengue and Zika viruses. Since the end of June this year, there were over 7 000 cases recorded in Foshan City, Guangdong Province, with majority of cases occurring in Shunde District. All cases were mild, with no severe or fatal cases.
A total of one CF case has been recorded in Hong Kong this year, which is an imported case. No local cases have been recorded. Due to the increase in temperature and rainfall in summer, mosquito infestation might be aggravated in Hong Kong. In addition, members of the public travel more frequently during summer holidays to regions where mosquito-borne diseases are endemic. As a result, Hong Kong has a high risk of occurrence of importation of CF cases again, leading to the potential risk of local transmission.
Recommended measures
The SCVBD endorsed the following ongoing and corresponding preventive and control measures implemented by the Government:
Enhanced Surveillance: maintain close monitoring of global and neighbouring regions' CF situations, including keeping abreast of the latest situation of CF through the communicable disease notification mechanism between Guangdong, Hong Kong and Macao. Continue to update doctors and hospitals on the latest epidemiological information and remind healthcare professionals to remain vigilant.
Laboratory testing: enhance local testing capabilities to ensure rapid diagnosis of suspected cases.
Vector surveillance and control: departments to collaborate with relevant sectors to strengthen vector surveillance and mosquito control during the summer. Pay attention to high risk spots and follow-up. The Government should also explore the latest development of mosquito control methods.
Case investigation and control measures: conduct prompt epidemiological investigations and vector surveys upon case detection; arrange patients to be admitted to hospital to receive treatment in mosquito-free environments.
Port health measures and travel advice: maintain inspections at boundary control points for vector control and environmental hygiene; maintain close liaison with industry stakeholders and provide health advice to them; strengthen health education for outgoing and returning travellers to affected areas.
Risk communication and publicity: disseminate information on CF and preventive measures through different channels, and provide schools and institutions with guidance on anti-mosquito measures.
Vaccine effectiveness monitoring: there is so far insufficient scientific evidence on efficacy and safety of existing CF vaccines. The Government should monitor the latest recommendations from the WHO and overseas health authorities.
The SCVBD affirmed that Hong Kong's multi-pronged approach on emergency preparedness has effectively prevented local CF transmission to date. Sustained implementation of these measures is crucial to address the importation risk.
The consensus statement of the SCVBD has been uploaded to the CHP website.

Seven persons arrested during anti-illegal worker operation
The Immigration Department (ImmD) mounted an anti-illegal worker operation codenamed "Contribute" today (January 15).During the operation, ImmD Task Force officers raided premises under renovation in a newly built public housing estate in Sheung Shui district.A total of six suspected illegal workers and one suspected employer were arrested. Thearrested suspected illegal workers comprise six men, aged 22 to 41. Furthermore, one man, aged 45, suspected of employing the illegal workers, was also arrested. An investigation into the suspected employers is ongoing, and the possibility of further arrests is not ruled out.
Apart from mounting the enforcement operation, ImmD officers and a promotional vehicle have been deployed to distribute "Don't Employ Illegal Workers" leaflets and convey the message in the estate.
An ImmD spokesman said, "Any person who contravenes a condition of stay in force in respect of him or her shall be guilty of an offence. Also, visitors are not allowed to take employment in Hong Kong, whether paid or unpaid, without the permission of the Director of Immigration. Offenders are liable to prosecution and upon conviction face a maximum fine of $50,000 and up to two years' imprisonment. Aiders and abettors are also liable to prosecution and penalties."
The spokesman stressed that it is a serious offence to employ people who are not lawfully employable. Under the Immigration Ordinance, the maximum penalty for an employer employing a person who is not lawfully employable, i.e. an illegal immigrant, a person who is the subject of a removal order or a deportation order, an overstayer or a person who was refused permission to land, has been significantly increased from a fine of $350,000 and three years' imprisonment to a fine of $500,000 and 10 years' imprisonment to reflect the gravity of such offences. The director, manager, secretary, partner, etc, of the company concerned may also bear criminal liability. The High Court has laid down sentencing guidelines that the employer of an illegal worker should be given an immediate custodial sentence.
According to the court sentencing, employers must take all practicable steps to determine whether a person is lawfully employable prior to employment. Apart from inspecting a prospective employee's identity card, the employer has the explicit duty to make enquiries regarding the person and ensure that the answers would not cast any reasonable doubt concerning the lawful employability of the person. The court will not accept failure to do so as a defence in proceedings. It is also an offence if an employer fails to inspect the job seeker's valid travel document if the job seeker does not have a Hong Kong permanent identity card. Offenders are liable upon conviction to a maximum fine of $150,000 and to imprisonment for one year. In that connection, the spokesman would like to remind all employers not to defy the law by employing illegal workers. The ImmD will continue to take resolute enforcement action to combat such offences.
Under the existing mechanism, the ImmD will, as a standard procedure, conduct an initial screening of vulnerable persons, including illegal workers, illegal immigrants, sex workers and foreign domestic helpers, who are arrested during any operation with a view to ascertaining whether they are trafficking in persons (TIP) and/or forced labour victims. When any TIP and/or forced labour indicator is revealed in the initial screening, the ImmD officers will conduct a full debriefing and identification by using a standardised checklist to ascertain the presence of TIP and/or forced labour elements. Identified TIP and/or forced labour victims will be provided with various forms of support and assistance, including urgent intervention, medical services, counselling, shelter or temporary accommodation and other supporting services. The ImmD calls on TIP and/or forced labour victims to report crimes to the relevant departments immediately.
For reporting illegal employment activities, please call the dedicated hotline 3861 5000, by fax at 2824 1166, email to anti_crime@immd.gov.hk, or submit "Online Reporting of Immigration Offences" form at www.immd.gov.hk.
