CHP investigates two additional local cases of dengue fever

Hong Kong (HKSAR) - The Centre for Health Protection (CHP) of the Department of Health is investigating today (August 21) two additional local cases of dengue fever (DF) and again urged the public to maintain strict environmental hygiene, mosquito control and personal protective measures both locally and during travel.

The first additional case involves a 59-year-old male patient with good past health, who developed fever, headache, retro-orbital pain, myalgia and arthralgia since August 17. He sought medical attention at the Accident and Emergency Department (AED) of St John Hospital as well as Queen Mary Hospital (QMH) on August 20. He is admitted to QMH and has all along been in a stable condition.

His blood sample tested positive for dengue virus serotype 1 upon laboratory testing.

Initial enquiries revealed that the patient lives alone in San Hing Street in Cheung Chau and recalled history of mosquito bite in Fa Peng Road in Cheung Chau. During the incubation period, the patient had travelled to Shunde and Guangzhou in Guangdong. This case is tentatively classified as a local case.

The second case involves a 43-year-old female patient with good past health, who developed fever, myalgia, arthralgia and rash since August 14.

She was admitted to Queen Elizabeth Hospital for treatment on August 20. She has all along been in a stable condition and her blood sample tested positive for dengue virus serotype 1 upon laboratory testing.

Initial enquiries revealed that the patient lives in Chuk Yuen (South) Estate in Wong Tai Sin. She had no travel history during the incubation period but had visited Lion Rock Park.

She recalled history of recent mosquito bite.

Her home contact has remained asymptomatic and has been put under medical surveillance.

For the remaining two cases among the four local cases of DF recorded on August 18, further laboratory testing revealed that the genetic sequence of the virus of one case (69-year-old female patient) was highly similar to the virus from the majority of Lion Rock Park cases earlier, while the virus of the other case (61-year-old male patient) could not be sequenced.

"We are working closely with the Food and Environmental Hygiene Department (FEHD) to assess and prevent possible spread of infection. The FEHD's vector investigations, surveillance and control are ongoing. Epidemiological investigations are ongoing," a spokesman for the CHP said.

"The CHP, together with the FEHD, will conduct a health talk at 1/F of Cheung Chau Municipal Services Building at 11am this Thursday (August 23) and another health talk at Chuk Yuen Estate Community Centre at 8pm this Friday (August 24) to deliver health advice.

"The CHP appeals to members of the public not to visit Lion Rock Park during the closure period in order to prevent contracting DF. People who had visited Lion Rock Park are advised to apply insect repellent for 14 days upon their last visit, and those with DF symptoms should seek medical advice as early as possible," the spokesman said.

CHP says sorry for mistake in dengue fever case analysis

The Department of Health?s Centre for Health Protection (CHP) said it made a mistake regarding a confirmed local case of dengue fever in Cheung Chau on Sunday, saying it was not caused by a different source of infection as previously announced but shared the same source as the case confirmed earlier on the island.

According to the CHP, the two cases involved an 84-year-old woman living on Hill Side Road on the island, who was confirmed to have contracted the acute mosquito-borne disease last Tuesday, and a 52-year-old man living on Tsan Tuen Road, whose infection was confirmed on Sunday.

The center originally announced that the man?s blood sample tested positive for the dengue virus serotype 3, in contrast to serotype 1 found in the 15 other cases before him, and concluded that this indicated more than one source of infection.

However, it said in a statement on Monday night that the latest laboratory testing results revealed the genetic sequences of the viruses in the two cases were highly similar.

As a result, repeat testing was done before it showed that the male patient?s blood sample was positive for dengue virus serotype 1, and not serotype 3 as previously announced.

The CHP apologized for the confusion and inconvenience caused by the error in the laboratory test result of the second Cheung Chau case, and promised to take measure to prevent similar incidents from happening in the future...

The cases of dengue fever in Hong Kong gradually decreased with no reported local infections for more than a week. But still, medical experts warned there's still a threat from imported cases.

From August 14 until last Tuesday, there are 29 confirmed cases, in which all of them contracted the virus near Lion Rock Park in Wong Tai Sin or the outlying island of Cheung Chau. And since then, there are no new cases reported.
