SINGAPORE, June 4 (Xinhua) -- The weekly number of new dengue cases reported in Singapore surged to an all time high over the seven days from May 26 to June 1, according to statistics from the city state's ministry of health released Tuesday.
There were 756 infections reported in the week, which is 43 more than the previous peak in September 2005 during the worst dengue epidemic in Singapore. About 14,000 people were infected in 2005, with 25 deaths reported.
By the noon of June 4, a total of 8,632 infections have been reported this year, despite efforts by authorities and the communities to carry out campaigns aimed to wipe out mosquitoes.
Last week, a 20-year-old man died from Dengue infection in the first death resulting from Dengue fever this year.
Prime Minister Lee Hsien Loong launched a national campaign in April to stamp out possible mosquito breeding spots.
Experts said this year the dominant dengue virus in Singapore is not the Den-2, as was the case over the past few years. As a result, few people have the immunity.
The Ministry of Health said the breakdown of infections for this month is 54 percent for Den-1, 28 percent for Den-2, 18 percent for Den-3. Few cases of Den-4 infections were reported.
In 2010, the highest weekly number of Dengue infections was 182, followed by 263 and 151 in the years 2011 and 2012, respectively.
There are now more than 40 active dengue clusters, with the majority of cases still centred on the eastern part of Singapore. However, clusters in the north and west have surfaced in recent weeks.
Dengue fever is an illness caused by infection with a virus transmitted by the Aedes mosquito, with the symptoms including fever, fatigue as well as joint and muscle pains. There are four serotypes of the virus normally seen in Singapore.
There is currently no effective drug for Dengue.
