Red tide sighted

     A red tide has been sighted over the past week, an inter-departmental red tide working group reported today (May 18).
 
     The red tide was spotted by staff of the Leisure and Cultural Services Department on May 12 at Silverstrand Beach, Sai Kung. A red flag was hoisted immediately. 
 
     The red tide has dissipated. No associated death of fish has been reported.
 
     A spokesman for the working group said, “The red tide was formed by Noctiluca scintillans, which is commonly found in Hong Kong waters and non-toxic.”
 
     The Agriculture, Fisheries and Conservation Department (AFCD) urged mariculturists at Ma Nam Wat fish culture zone to monitor the situation closely and increase aeration where necessary.
 
     Red tide is a natural phenomenon. The AFCD’s proactive phytoplankton monitoring programme will continue monitoring red tide occurrences to minimise the impact on the mariculture industry and the public. read more

Update on number of dengue fever cases

     The Centre for Health Protection (CHP) of the Department of Health today (May 18) 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 May 4 to 17, the CHP recorded two confirmed DF cases and the patients had been to Thailand and Vietnam during the incubation period respectively.  
 
     As of yesterday (May 17), 21 cases had been confirmed this year, all of which were imported cases. The cases were mainly imported from Thailand (eight), the Philippines (six), Cambodia (two) and Vietnam (two).
 
     DF remains endemic in some areas in Asia. In Guangdong, there were 17 cases this year as of May 14. The latest figures for 2018 reveal that 10 446 cases have been recorded in Thailand, 979 in Singapore (since December 31, 2017) and 34 in Japan. In the Americas, the latest figures indicate that 90 858 and 7470 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 concentration of DEET of up to 30 per cent.
 
     The public may refer to the CHP’s tips for using insect repellents for details. read more

Grading of beach water quality released

     The Environmental Protection Department (EPD) today (May 18) released the latest grading of water quality for 37 gazetted beaches and one non-gazetted beach (Discovery Bay) that are open for swimming.
        
     Twenty beaches were rated as Good (Grade 1), 11 as Fair (Grade 2) and seven as Poor (Grade 3).

     Compared with the grading released last week, Big Wave Bay Beach, Golden Beach, Pui O Beach and Shek O Beach have been changed from Grade 1 to Grade 2, and Approach Beach, Casam Beach and Ma Wan Tung Wan Beach from Grade 2 to Grade 3.
      
     “The changes are generally within the normal range of fluctuation of the bacteriological water quality of the beaches,” an EPD spokesman said.
      
     Under the present grading system, beaches are classified into four grades according to the level of E. coli in the water. Grades are calculated on the basis of the geometric mean of the E. coli counts on the five most recent sampling occasions.
      
     While the ratings represent the general water quality at the beaches, the EPD spokesman reminded members of the public that water quality could be temporarily affected during and after periods of heavy rain. Bathers should avoid swimming at beaches for up to three days after a storm or heavy rainfall.
 
     A summary of beach grades is published weekly before the weekend. The latest beach grades based on the most current data may be obtained from the department’s websites on Beach Water Quality (www.beachwq.gov.hk and www.epd.gov.hk/epd/beach) or the beach hotline, 2511 6666. read more
