Challenges that Hinder Dengue Prevention
In this modern age, there are lots of ways that can help prevent dengue in Singapore. This includes practising the National Environment Agency’s (NEA) Mozzie Wipeout, using insect repellent sprays in and around your homes, regularly inspecting your homes and premises for mosquito breeding sites, etc.
However, like any other prevention method, some factors can prevent the smooth operations of such preventive measures. As a result, this leaves many vulnerable to vector-borne diseases that may contribute to the dengue cases on the island.
With that, we will discuss some of the challenges that hinder dengue prevention in Singapore along with the dangers of not being able to prevent dengue. We will also share some of the plausible solutions to ensure the efficacy of various dengue prevention methods.
What are the challenges that can hinder effective dengue prevention?
As mentioned earlier, some factors can prevent the smooth operations of dengue preventive measures. Among these challenges are increased time spent at home, urbanisation and population growth, weather variability, and communal responsibility.
Increased time spent at home
Due to the pandemic, many people are still working from home during this period. This means more blood meals for the day-biting Aedes aegypti mosquito. While some may have gone back to the office, it doesn’t discount the fact that mosquitoes tend to hide in dark corners and prey on their blood meals during the night.
Urbanisation and population growth
As of end-June 2021, Singapore has a total population of 5.45 million. Living in a highly urbanized setting, the risk of contracting dengue is high, due to the proximity of living spaces and conducive breeding habitats for mosquitoes such as stagnant water in potted plants and clogged gutters.
Constant changes to Singapore’s tropical climate can cause the re-emergence of dengue through its interactions with biotic and abiotic factors. In fact, the NEA has urged everyone to remain vigilant in its latest advisory as dengue cases could increase towards the year-end with the approaching monsoon season.
Dangers of not being able to prevent dengue
As a mosquito-borne disease with no specific treatment for dengue fever, dengue can cause a wide spectrum of diseases, ranging from subclinical disease to severe flu-like symptoms. In severe cases of dengue, it can cause fatal complications due to plasma leaking, fluid accumulation, respiratory distress, severe bleeding, or organ impairment.
If you suspect that you have dengue or showing symptoms suggestive of dengue, you should see a medical practitioner immediately to prevent your condition from worsening. Avoid getting mosquito bites as the virus may be circulating in your blood, and you may transmit the virus to uninfected mosquitoes, who in turn infect others. And the cycle continues.
How to prevent dengue transmission?
While there’s still no vaccine that’s effective in preventing dengue, you can control and prevent the transmission of the dengue virus with several preventive measures. This includes using personal protection from mosquito bites, cleaning/removing potential mosquito breeding sites and activating vector control.
Personal protection from mosquito bites
In this modern age, various items can keep insects out of your house such as window screens, repellents, coils, and vaporisers. By lining your windows and doors with screens, you’re creating a barrier that prevents mosquitoes from entering your house. Likewise, wearing clothing that minimises skin exposure to mosquitoes and applying mosquito repellent on your body helps prevent mosquito bites.
Cleaning / removing potential mosquito breeding sites
Female Aedes aegypti mosquitoes tend to lay their eggs in standing water. What you can do to prevent their population from growing is to remove stagnant water regularly and clean the water containers regularly. This also helps to reduce the population in and around your house.
Activate vector control
In response to dengue outbreaks across the island, the spraying of insecticides works to prevent the widespread transmission of dengue. Similarly, you can hire dengue prevention services in Singapore to destroy the mosquito larvae and the entire population over time by larviciding your neighbourhood.
If you’re looking to keep mosquitoes out of your house, you may want to consider enlisting help from professionals like PestBusters. Our integrated pest management programme is designed to strike out and eliminate mosquitoes from your house. Among the strategies we have in eliminating mosquito breeding grounds are larviciding, BTI (Bacillus Thuringiensis Israelensis) and misting.
For indoor purposes, we harness the use of BTI, a biological agent that is specially formulated to eliminate mosquito larvae within 2 to 24 hours. We’ll first spray the substance into stagnant waters where you found the larvae. Once the larvae ingest the agent via filter-feeding, their guts will be destroyed and die within a day. You can rest assured that this agent is harmless to humans.
