Why 2026 is a Dengue Year You Cannot Ignore

Residents of Bangladesh are well aware of the seasonal challenges introduced by the monsoon, particularly the widespread transmission of the dengue virus within local communities. As of early May 2026, the Directorate General of Health Services (DGHS) has documented more than 2,600 confirmed dengue cases nationwide. With the peak mosquito breeding season now underway, implementation of rigorous preventative measures over the next four months will be critical.

Professor Dr. ABM Abdullah, Professor of Medicine and former Dean of Medicine at Dhaka Medical College Hospital — one of Bangladesh’s most respected physicians and a regular expert voice on dengue prevention — puts it plainly: “These are household mosquitoes. Water must not sit for more than two days.” The Aedes aegypti mosquito is a domestic mosquito. It lives where you live. And it can be controlled — but only if you know exactly where to look.

This is a practical, no-nonsense guide for Bangladeshi families covering where the mosquito actually breeds in your home, how to do the daily 5-minute check that stops it cold, which protection products actually work, and what to do if symptoms appear.

Where Aedes Mosquitoes Actually Breed in Your Home

Here are the most common breeding spots in a typical Bangladeshi home, and how to fix each one:

1. Air Conditioner Drip Trays

Your AC drips condensate water continuously during summer. If that water collects in a tray, bucket, or pools at the outdoor unit base — you’ve created a perfect Aedes nursery. Fix: Empty the tray daily, or fit a drainage pipe that flows directly outside without pooling.

2. Flower Pots and Plant Saucers

The saucer under each flower pot collects water every time you water the plant. Fix: Either remove saucers entirely, or fill them with sand to absorb water without creating mosquito habitat.

3. Refrigerator Drip Pan

Modern refrigerators have a drip pan at the back that collects condensation. Most people never check it. Fix: Pull out your fridge once a week and empty the pan. Wipe it dry.

4. Rooftop Water Tanks and Pots

If your apartment building uses overhead water tanks, check that lids are sealed. Open water storage on the roof breeds millions of mosquitoes. Fix: Cover ALL water storage with tight-fitting lids.

5. Discarded Containers in Balconies

Old plastic bottles, paint cans, broken pottery, abandoned containers — any vessel that collects rainwater for 48+ hours becomes a breeding site. Fix: Walk your balcony and terrace weekly. Throw out anything that can hold water.

The 5-Minute Daily Dengue Check

This routine alone — done consistently — reduces dengue risk in your home by an estimated 80%. The remaining 20% comes from mosquitoes that fly in from neighbouring buildings. That’s where physical protection comes in.

Mosquito Protection Products That Actually Work

Skin Repellents (DEET or Picaridin)

Your front-line daytime defence. DEET (20-30%): the most-tested mosquito repellent in the world. Apply to exposed skin — arms, legs, neck. Lasts 6-8 hours. Safe for children over 2 months at lower concentrations. Picaridin (10-20%): equally effective, less greasy, doesn’t damage plastics.

Plug-In Vaporizers

Goodknight, Mortein, and similar vaporizers work — but only in enclosed rooms with closed windows. Best use case: plug into bedroom and living room during peak biting hours (5-7 PM). Avoid mosquito coils indoors — they release particulate matter harmful to lungs and children.

Window and Door Screens

The single most cost-effective long-term investment. A properly fitted mesh screen on every window prevents mosquito entry entirely during evening hours. For doorways — where entering and exiting creates entry points — a magnetic screen door is the practical solution that closes automatically without any action from you.

Warning Signs You Cannot Ignore

Most dengue cases are mild and resolve in 5-7 days with rest, hydration, and paracetamol. But some cases progress to severe dengue, which can kill within 48 hours if untreated.

What to Do If Someone in Your Family Gets Dengue

Days 1-3 (Febrile Phase):

• Get a CBC (Complete Blood Count) blood test to check platelets
• Use only paracetamol for fever (Napa, Ace) — NEVER aspirin or ibuprofen (they thin blood and worsen bleeding risk)
• Push fluids: ORS, coconut water (daab), papaya leaf juice, plain water
• Complete bed rest

Days 4-6 (Critical Phase — Monitor Closely):

• Repeat CBC every 24 hours to track platelet count
• If platelets drop below 50,000 or warning signs appear — hospitalise immediately

Pregnant Women and Children: Special Precautions

Pregnant women with dengue face additional risks including premature birth and vertical transmission. Use DEET repellent daily (up to 30% is safe in pregnancy per CDC), wear long sleeves during peak biting hours, and get tested at the first sign of fever.
