DENGUE cases in Klang district have seen a drop from January to April 19 this year compared to the corresponding period last year.
Klang Municipal Council (MPK) Health and Environment Department director Azmi Muji said 4,699 people were admitted in hospitals for dengue fever up to April 19 compared to the same period last year, which saw 6,391 people confirmed with the illness.
“Based on this data, we are seeing a downward trend in dengue cases. We believe it is due to the active approach of people cleaning up their surroundings.
“The virus claimed seven lives this year compared with three from January to April 19 last year, ” he added. In 2019, Klang district recorded a total of 13,057 cases – the highest dengue statistic recorded since 2010 – with a total of seven deaths.
Azmi added that the downward trend in cases was due to the government’s movement control order (MCO) to stop the spread of Covid-19 which has had a positive impact on dengue cases.
“People are at home and this has led to the cleaning up of both the inside and areas within their compounds.
“Another factor in the spread of the dengue virus is human movement. Less movement means fewer chances of a healthy person being bitten by the Aedes mosquito and becoming infected, ” he said.
He added that with the MCO, the virus had been hindered from spreading within the community.
“In the past, our health inspectors used to advise people to clean their homes but the excuse was their busy schedules. But now people are cleaning their homes and removing mosquito breeding sites in and outside their houses, ” he said.
Azmi added that a clean-up campaign to wipe out mosquito breeding grounds was ongoing and the department had intensified efforts since early March.
“Most of the time, the mosquito larvae are found in plastic drink bottles and cups discarded in drains or in between shrubs. The best approach to fighting dengue is by eradicating mosquito breeding habitats at source, ” he said.
Fogging exercises and spraying of insecticides to control the adult mosquito population was also a way to prevent dengue.
“Other than that, we noticed that less litter had been dumped on the roads as fewer people were out and about, ” he said, adding that this meant there were fewer breeding spots for the mosquito.
Dengue is a major problem in Selangor, which recorded 72,543 cases last year, with 56 deaths.
