Essential dengue prevention tips you must be aware of to safeguard your home

If you’re not already aware of the rising dengue cases, have you been living under a rock? …And did you check it for mosquitoes? But fear not; we’ll get you up to speed. In this article, we’ll take you through the current case numbers, what the National Environment Agency (NEA) is doing to tackle this issue, and most importantly, dengue prevention tips to protect yourself, your loved ones, and your community from this growing health threat.

The buzzing numbers

As of February 13, 2025, Singapore is experiencing a significant increase in dengue cases. In the first 6 weeks of the year, the country has reported 599 cases of dengue.

In the week ending February 8, 2025, 113 cases were reported, marking a 59-case rise from the previous week. There are currently 15 active dengue clusters, with 5 classified as high-risk areas.

The overall count of dengue cases has also been on the rise. In 2024, Singapore reported a total of 13,655 dengue cases, a 37.2% increase from the 9,949 cases in 2023. Between October and December 2024, over 5,600 mosquito breeding sites were identified across the island, marking an increase of approximately 15% compared to the previous quarter.

According to authorities, the Dengue virus serotype 2 (DENV-2) has been the most common strain since September 2023, following periods where DENV-1 and DENV-3 were dominant in 2023. The population’s immunity to all four Dengue virus serotypes remains low, which could be a reason for the rise in number of cases year-on-year. With the ongoing presence of these risk factors, there is a potential for a rise in dengue cases if measures are not taken to address the situation.

Thankfully, only 2 cases of Zika virus have been reported so far, but it would be prudent not to drop any safety measures yet.

What’s causing this dengue frenzy? 

For one, the Dengue virus serotype 1 (DENV-1), previously less prevalent, has been making a comeback. And, as if that weren’t enough, the warmer months from May to October, when the Aedes mosquito vector thrives, usually witness higher dengue transmission. This is due to the mosquitoes multiplying the Dengue virus faster. It’s like the perfect storm for dengue, and it calls for immediate action.

Dengue symptoms you should know

Before we dive into prevention, let’s talk symptoms. 

Dengue and Zika infections can sneak up on you, so it’s essential to know what to look for.

Dengue symptoms:

• Sudden onset of fever for two to seven days.
• Severe headache with retro-orbital (behind the eye) pain.
• Joint and muscle pain.
• Skin rashes.
• Nausea and vomiting.
• Bleeding from the nose or gums.
• Easy bruising of the skin.

Zika symptoms:

• Fever.
• Rash.
• Joint pain.
• Muscle pain.
• Headache.
• Conjunctivitis (red eyes).

What is NEA doing about this?

The NEA has an ace up its sleeve – Project Wolbachia. This programme produces millions of non-biting male Aedes aegypti mosquitoes every week and releases them to specific locations to mate with the females. 

But why produce more mozzies when we already have a growing dengue problem? 

Well, these guys are a little different. 

These males carry the Wolbachia bacteria, ensuring that the resultant eggs from mating don’t hatch. This strategy helps suppress the mosquito population.

Simply put, we’re fighting fire with fire. 

While Project Wolbachia has seen some success (with Aedes aegypti mosquito populations falling by up to 98% in areas like Tampines, Yishun, and Choa Chu Kang), it hasn’t led to consistent drops in dengue cases across the board since its launch in 2016.

Why, you ask? Well, if there are tons of mosquitoes out there, the Wolbachia sent out can’t compete. They’d be overwhelmed. So, while Wolbachia is a key player in the game, it needs some backup.

What you can do

Now, let’s discuss what you can do to combat the spread of dengue and Zika, focusing on the “SAW” approach:

• Spray insecticide: Regularly spray insecticide in dark corners around your home where mosquitoes like to lurk.
• Apply insect repellent: Make it a habit to apply insect repellent regularly, especially if you spend time outdoors.
• Wear protective clothing: Wear long-sleeve tops and long pants to minimise your skin’s exposure to mosquito bites.

Community efforts

Remember, you’re not in this fight alone. You can also rally the community to practise the “B-L-O-C-K” steps:

• Break up hardened soil in your plant pots and garden areas to eliminate mosquito breeding spots.
• Lift and empty flowerpot plates – don’t let them become tiny mosquito nurseries.
• Overturn pails and wipe their rims to ensure no water collects, creating a mosquito paradise.
• Change water in vases regularly to prevent mosquito larvae from developing.
• Keep roof gutters clear and add BTI insecticide inside to thwart mosquito breeding.

This isn’t just about protecting your home; it’s about creating a mosquito-free environment for everyone. So, all hands on deck, yeah? 

Wrapping up

In conclusion, the surge in dengue cases is indeed concerning, but by following these essential dengue prevention tips and uniting with your community, you can be a part of the solution. 

Let’s fight back against the buzzing menace and make our homes safer for all.
