Southeast Asia: Dengue Fever [Update]

13 January 2020

The Centre for Health Protection (CHP) of the Department of Health today (January 10) reported the latest number of dengue fever (DF) cases, and strongly urged the public to maintain strict environmental hygiene, mosquito control and personal protective measures both locally and during travel.

From January 3 to 9, the CHP recorded four imported DF cases. The patients had respectively been to the Philippines (three cases) and Thailand (one case) during the incubation period.

As of January 9, a total of four cases of DF had been recorded in 2020, all of which were imported cases. In 2019, 198 cases were recorded (comprising 197 imported cases and one local case), as compared with 163 cases recorded in 2018. The imported cases in 2019 were mainly from Thailand (34), Malaysia (27) and the Philippines (25).

The CHP has been closely monitoring the latest DF situation in neighbouring and overseas areas. DF is endemic in many tropical and subtropical areas of the world. According to the World Health Organization, some Asian countries were experiencing unusually high numbers of DF cases in 2019. The numbers of cases in some countries were significantly higher than the numbers in 2018, including Malaysia, the Philippines, Singapore, Thailand and Vietnam.

Separately, according to the Health Commission of Guangdong Province, as of November 30 last year, a total of 5 986 cases had been recorded in Guangdong in 2019, which was significantly higher than that in the same period in 2018 (3 250 cases). In Taiwan, 640 cases (including 100 local cases) had been recorded in 2019 and as of yesterday, seven imported cases (none local) have been recorded in 2020.

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 (www.chp.gov.hk/files/pdf/df_imported_cases_and_overseas_figures_eng.pdf). Members of the public should stay vigilant and carry out effective mosquito prevention and control measures.

Mainland China: Pneumonia [Update]

10 January 2020

The Centre for Health Protection (CHP) of the Department of Health today (January 9) received notification from the National Health Commission (NHC) on the latest progress of the identification of the pathogen for the reported cluster of pneumonia cases in Wuhan, Hubei Province.

According to information from the NHC, the Mainland's expert group has preliminarily determined that the pathogen of the cluster of viral pneumonia cases occurring in Wuhan is a kind of novel coronavirus. The relevant Mainland laboratory has detected a novel coronavirus and obtained the whole genome sequence of the virus.

The expert group revealed that molecular testing of 15 cases returned positive results for the novel coronavirus, and the virus was also isolated from a sample of a case. Under electron microscopy, the virus showed the typical appearance of coronavirus. The expert group added that the testing for nucleic acid, genome and antibodies from the samples of patients could be completed within a short period, thereby assisting in confirmation of the pathogen. Nonetheless, the virus isolation and pathogenicity studies would take several weeks. Moving forward, further deliberation by experts taking into consideration pathogen research, epidemiological investigation and clinical assessment is needed.

On the other hand, the World Health Organization (WHO) earlier pointed out that there is limited information to determine the overall risk of this reported cluster of pneumonia. The WHO emphasised that more comprehensive information is required to understand the current status and epidemiology of the outbreak, and the clinical picture. Further investigations are also required to determine the source, modes of transmission, extent of infection and countermeasures implemented.
