Update on number of dengue fever cases

     The Centre for Health Protection (CHP) of the Department of Health today (October 26) reported the latest number of 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.
 
     From October 19 to 25, the CHP recorded five imported DF cases. The patients had been to Guangdong, Mainland China (three cases, including one case epidemiologically linked to a case from last week), India (one case) and Thailand (one case) during the incubation period. 
 
     A spokesman for the DH advised members of the public that the health authority of Guangdong announced earlier on that Guangdong has entered the peak season of DF and the number of local cases recorded was higher than the average in the same period from 2015 to 2017. Members of the public are reminded to adopt personal protective measures against mosquitoes to prevent mosquito-borne diseases such as DF when visiting Guangdong.

     As of yesterday (October 25), 132 cases had been confirmed this year, of which 29 were local cases and 103 were imported cases. The imported cases were mainly from Thailand (32), Mainland China (22) and the Philippines (16). 

     DF remains endemic in some areas of Asia and beyond. The latest figures for 2018 revealed that 67 968 cases had been recorded in Thailand, 2 319 in Singapore (since December 31, 2017) and 150 in Japan. In Taiwan, 157 local cases have been recorded to date in 2018. In the Americas, the latest figures indicated that 203 157 and 48 926 cases have been filed in Brazil and Mexico respectively in 2018.
 
     The public should take heed of the following advice on mosquito control:
 

  • Thoroughly check all gully traps, roof gutters, surface channels and drains to prevent blockage;
  • Scrub and clean drains and surface channels with an alkaline detergent compound at least once a week to remove any deposited mosquito eggs;
  • Properly dispose of refuse, such as soft drink cans, empty bottles and boxes, in covered litter containers;
  • Completely change the water of flowers and plants at least once a week. The use of saucers should be avoided if possible;
  • Level irregular ground surfaces before the rainy season;
  • Avoid staying in shrubby areas; and
  • Take personal protective measures such as wearing light-coloured long-sleeved clothes and trousers and apply insect repellent containing DEET to clothing or uncovered areas of the body when doing outdoor activities.

     To reduce the risk of infections spread by mosquitoes, apart from general measures, travellers returning from affected areas should apply insect repellent for 14 days (DF) or at least 21 days (Zika virus infection) upon arrival in Hong Kong. If feeling unwell, seek medical advice promptly and provide travel details to the doctor. DEET-containing insect repellents are effective and the public should take heed of the tips below:
 
  • Read the label instructions carefully first;
  • Apply right before entering an area with risk of mosquito bites;
  • Apply on exposed skin and clothing;
  • Use DEET of up to 30 per cent for pregnant women and up to 10 per cent for children*;
  • Apply sunscreen first, then insect repellent; and
  • Re-apply only when needed and follow the instructions.
 
* For children who travel to countries or areas where mosquito-borne diseases are endemic or epidemic and where exposure is likely, those aged 2 months or above can use DEET-containing insect repellents with a DEET concentration of up to 30 per cent.

     The public may refer to the CHP’s tips for using insect repellents for details. read more

CHP investigates outbreak of acute gastroenteritis at kindergarten-cum-child care centre in Tuen Mun

     The Centre for Health Protection (CHP) of the Department of Health is today (October 26) investigating an outbreak of acute gastroenteritis (AGE) at a kindergarten-cum-child care centre in Tuen Mun, and hence reminded the public and management of institutions to maintain personal and environmental hygiene against AGE.

      The outbreak involves seven boys and 13 girls aged 2 to 5, as well as one female staff member, who developed fever, diarrhoea and vomiting since October 24. Eighteen sought medical attention and two of them required hospitalisation for further management. All patients have been in a stable condition.

     Upon laboratory testing, the stool specimen of one affected child tested positive for norovirus and sapovirus.

     Officers of the CHP conducted a site visit and provided health advice to the staff of the school concerning proper and thorough disinfection, proper disposal of vomitus, and personal and environmental hygiene. The school has been put under medical surveillance.
 
     The CHP’s investigations are ongoing.
 
     A spokesman for the CHP advised members of the public to take heed of the following preventive measures against gastroenteritis:
 

  • Ensure proper personal hygiene;
  • Wash hands thoroughly before handling food and eating, after using the toilet or after changing diapers;
  • Wear gloves when disposing of vomitus or faecal matter, and wash hands afterwards;
  • Clean and disinfect contaminated areas or items promptly and thoroughly with diluted household bleach (by adding one part of bleach containing 5.25 per cent sodium hypochlorite to 49 parts of water). Wash hands thoroughly afterwards;
  • Maintain good indoor ventilation;
  • Pay attention to food hygiene;
  • Use separate utensils to handle raw and cooked food;
  • Avoid food that is not thoroughly cooked;
  • Drink boiled water; and
  • Do not patronise unlicensed food premises or food stalls.
