Latest Dengue Death in Singapore, Sparks New Warning

Authorities in Singapore are warning that Singapore’s most deadly outbreak of dengue fever since 2005 could get worse, after the disease claimed its seventh victim despite a vigorous effort by the government to control the epidemic.

More than 20,000 cases of the tropical, mosquito-borne disease have been identified in Singapore so far in 2013, spawning a series of multi-lingual YouTube videos about and a “Do The Mozzie Wipeout” campaign, launch in April, that promotes a series of at-home steps one can go through to kill mosquitoes and stop the disease from spreading.

In recent months the National Environment Agency, or NEA, has continued to boost measures to bring the rate of infection down by asking for public suggestions about how to make the fight against dengue more fun and engaging, particularly for children.

The mosquito-borne chikungunya virus appears to have become endemic in Singapore, after it had seemingly been eradicated.

The dengue-like disease took hold in April and there have been 924 cases this year - of which 881 were locally transmitted. Last week, there were 36 new cases.

The National Environment Agency (NEA) said the bulk of the infections have been in the Sungei Kadut and Bukit Timah/Holland areas, although four of last week's cases were in the Defu Lane and Defu Avenue areas.

NEA: WE DO NOT UNDERSTAND WHY SO MANY DENGUE CASES THIS YEAR

Dengue this year has consistently been a big issue with over 20,000 cases reported so far this year. Despite this, NEA is not sure of the reasons behind the higher number of cases. 

There have also been 7 deaths due to the disease this year and authorities have warned the public that they must do everything they can to prevent the disease from spreading.

The number of reported cases each week has remained around the 400 to 500 mark while in previous years, the numbers would usually start to drop dramatically by this time of year.

Why Singapore has lost the war against dengue

The Malaysian Insider, 20 Nov 2013

It is disturbing to read that dengue cases in Orchard Road continue to rise. For this year (the first 45 weeks), the average number of cases reported each day was around 62 for the whole country.

While Singapore has weathered many challenges, we seem powerless against dengue fever.

The reasons we have not won the war against dengue fever are obvious. First, if one complains about mosquito infestation in one’s neighbourhood, there would be a one-off response. Without a permanent solution, the problem would recur in no time. Second, there is a lack of coordination in dealing with certain mosquito breeding sites.

GRACE FU: DENGUE PATIENTS NEED TO AVOID GETTING BITTEN

Speaking to reporters on the sidelines of the Yuhua Open House, Ms Fu stressed the importance of keeping the surroundings free of mosquito breeding sites.

She added: “For patients of dengue fever, it’s also important for them to prevent themselves from (getting bitten by) the mosquitoes. 

“We have to stop the mosquito-to-human and human-to-mosquito transmission in order to control the incidence of dengue.

Singapore – City of Dengue
Clean and green Singapore has a new name: City of Dengue

The deadly mosquito-transmitted disease has claimed its seventh victim this year – a 53-year-old woman who died from dengue on Saturday, 15 November, 2013 – and is showing no signs of abating. Even Orchard Road, the city’s most popular shopping belt, and Somerset are not spared the fever.

While this is attributed to a sudden spike in temperature conditions and weaker immunity against the dengue Type One virus, the lack of coordination in dealing with mosquito breeding sites between the National Environment Agency (NEA) and town councils coupled with poor upkeeping is, unfortunately, a recipe for disaster.

Additionally, drains clogged with fallen dead leaves, branches, twigs and trash tend to collect stagnant water, thereby creating potential mosquito breeding spots. The sudden climate change makes matters worse

Singapore launches dengue web series, ‘The Silent War’ as outbreak nears 20,000 cases

The Singapore Ministry of the Environment and Water Resources (MEWR) has released the first two videos on the web series, “The Silent War” on their You Tube page this week, which documents the behind the scenes activities by the National Environmental Agency (NEA) during the 2013 dengue fever epidemic.

The Silent War is an 8-episode reality web series produced by Project Peanut.

The first episode titled “The Crisis” looks at the headlines behind the current outbreak, including the fact that some people have died from it.

Dengue dread spreads to Orchard's offices, homes

The Orchard Road lights are up and ready to usher in the Christmas festivities. But an unwelcome visitor is threatening to spoil the party

The number of dengue cases in the Orchard Cluster continues to climb, hitting 82 on Friday.

What's more, the threat no longer seems limited to the Orchard Gateway construction site, as an increasing number of individuals working and living in the area have started falling prey to the mosquito menace.

The 53 construction workers at the site still make up the bulk of the cases in the cluster. But the remaining 29 victims come from the gaggle of high-end offices and homes in Orchard Road.

Taking the sting out of dengue

In 2008, it was reported that the Health Ministry would undertake an experiment to release genetically-modified mosquitoes to fight Aedes aegypti mosquitoes, the main carriers of the dengue virus. Was it a success? How effective have we been in efforts to control dengue fever? Deputy director-general of Health (public health) Datuk Dr Lokman Hakim talks to Chandra Devi Renganayar and Suzanna Pillay to get an insight into efforts to combat the scourge.

Question: Where were the genetically-modified (GM) mosquitoes first released?

Answer: Our original proposed trial site was in Pulau Ketam, but our preliminary surveys indicated that the site was unsuitable for the trial. Instead, a trial site in Pahang was found to be ideal and the release was conducted in this site. The trial, the first open release of male transgenic mosquitoes in Asia, was conducted on Dec 21, 2010, in an uninhabited forest (non-reserve forest land owned by the government off Jalan Tentera/Lebuhraya Bentong-Raub) in Bentong, Pahang.

Dengue death: Indonesian is first foreigner to die of disease in Singapore


Another dengue death has been reported in Singapore. The latest victim is an Indonesian man who most likely contracted the disease overseas but died after being treated for dengue in Singapore, said the Ministry of Health and the National Environment Agency on Wednesday.

A big battle against a small pest


So finally, the G is weighing heavily into the dengue fight, when it’s about to hit 1,000 cases a week. Minister Vivian Balakrishnan has called a press conference to hammer home the message to those people who are still unaware the mosquito could be breeding in their homes.

Good thing he did because, seriously, it was strange for a minister to come down so heavy on whether some hawker centres had their ceilings are cleaned and trading barbs with the opposition when there are far more issues to worry about.

ST chose to dwell on Dr Balakrishnan’s warnings and admonitions in its Page 1 story, while TODAY went straight into nuts and bolts of the dengue battle. TODAY reported that some $85m has been budgeted for the year’s dengue battle, up from $70 million spent last year.



Dengue cases expected to top 10,000 this weekend

The number of dengue cases is expected to hit the 10,000-mark this weekend. Authorities said the actual count would be updated tomorrow (June 17).

At last count on Friday, there were 42 new cases, bringing the total to 9,960 so far this year.

For the past week, the number of new cases daily has been consistently above 40. Preventive efforts have been taken across the island, including quick temperature scans in schools.

DR VIVIAN BALAKRISHNAN: DENGUE SET TO GET WORSE
Dr Vivian Balakrrishnan has said that the Dengue epidemic is set to get worse as the peak dengue season is still yet to arrive.

Speaking at a press conference yesterday, the Minister for Environment and Water Resources also revealed that locals were prone to the type of dengue found due to lower immunity. The strain of dengue present now also spreads more easily.

He said that it is a "paradox of process" that Singaporeans have a lower immunity to the strain than regional neighbours



NEA going all out in war against dengue

SINGAPORE is at a "critical juncture" in the current dengue epidemic, with the number of fresh cases expected to reach close to 1,000 this week. 

Minister for the Environment and Water Resources Vivian Balakrishnan warned of this yesterday in the light of an all-time high of 820 new cases recorded in the week which ended last Saturday.

The epidemic is driven by factors such as low population immunity against the virus and the continued transmission of the virus with high epidemic potential.

More asking for dengue tests at clinics as numbers rise
Singapore is in the grip of what could be its worst dengue epidemic, with 9,693 cases diagnosed so far this year. From Sunday till 3pm yesterday, there were 397 new cases of dengue. -- ST PHOTO: JOYCE FANG 

AS DENGUE numbers continue to climb in Singapore, more patients at some private clinics are asking for blood tests to diagnose the disease. 

Such tests cost at least $40 at private clinics The Straits Times spoke to, but those with fever seem to want to play it safe. This, despite doctors saying dengue blood tests are accurate only if a fever persists for a few days. 

At the Healthway clinic in Tampines Street 71, about four in 10 patients with fever have been asking for these tests to find out if they have the disease, resident doctor Philip Koh said. This is in contrast to last year, when Dr Koh saw virtually no such requests.

Weekly dengue-fever infections surge to a record

Singaporean health officials are stepping up efforts to beat back a tropical-disease outbreak that could become the city-state’s worst ever.

More than 9,400 people here have been infected by the mosquito-borne dengue virus so far this year, resulting in two deaths, according to the National Environment Agency. Weekly counts surged to an all-time high of 820 cases in the week that ended June 8, topping the previous record of 713 cases in 2005.

Officials believe the severity of the current epidemic will surpass that of Singapore’s worst dengue outbreak that year, when authorities logged 14,006 confirmed cases. The number of deaths in 2005 ended at 27, a higher proportion than the current outbreak.

NEA immediately steps up dengue control measures in PM Lee’s constituency


After a second dengue death of a man living in Ang Mo Kio Avenue 3 was reported on Sunday (9 Jun), NEA immediately stepped up control and preventive measures in Ang Mo Kio. Ang Mo Kio GRC is, of course, PM Lee’s constituency.

Yesterday afternoon (10 Jun), cleaners were seen clearing drains while NEA officers combed the area for potential breeding spots. They inspected drains, flower pots and even plants that could potentially trap water. Their presence was clearly felt by the Ang Mo Kio residents.

The second person who died is a 60-year-old Singaporean living in Ang Mo Kio Ave 3.



TTSH issues statement on 2 dengue patient deaths

There have been questions on the two dengue deaths that had occurred at TTSH. We would like to share the following responses with you on our process. We hope to seek your assistance in helping the public to understand that although dengue can be deadly, it is for most a self-limiting infection and most of us recover from dengue.

It is unfortunate that there are currently no antiviral medications to treat dengue. All we can do is to keep patients hydrated and wait for their bodies to fight the infection.

For a few us, the disease would regrettably prove stronger even with aggressive medical interventions such as intravenous fluids, blood transfusions, and organ support.



Teo Ho Pin On Mosquito Breeding 

Sembawang-Nee Soon Town Council was fined $200 after National Environment Agency found 14 mosquito larvae in the water tanks on the rooftops of blocks 896C and 899A in Woodlands

As the mosquito larvae were found in the water tanks, it raises the question as to whether water drawn from those water tanks was safe for consumption without prior boiling. Neither NEA nor Public Utilities Board, the national water agency, appears to have any press releases on their websites regarding this matter

Coordinating Chairman for PAP-managed town councils and Member of Parliament Teo Ho Pin said, "Water tanks have got many areas which are difficult to access for normal inspection and become very challenging.  You have breeding in some of these places because the birds actually bring leaves and twigs and choke our rooftop drains and it is quite difficult to inspect rooftops every day.
