Dengue Prevention & Warning Signs

Most dengue infections are actually mild — a large share produce no noticeable symptoms at all. When symptoms do appear, typically 4 to 10 days after the mosquito bite, they usually include: sudden high fever, severe headache, pain behind the eyes, joint and muscle pain (dengue's old nickname, "breakbone fever," comes from exactly this), and sometimes a skin rash. Most people recover within about a week with rest and supportive care.

A doctor will typically evaluate a combination of symptoms, timing, and a blood test — usually a complete blood count to check platelet levels, sometimes alongside a dengue-specific test (NS1 antigen or IgM antibody testing). If fever continues for three days or more, a full blood picture is generally recommended to track how platelet counts are trending, since falling platelets are part of what's monitored in a developing case.

There is no specific antiviral cure for dengue — treatment is entirely supportive. That means: paracetamol for fever and pain (not more than the recommended dose in 24 hours), plenty of fluids (water, soups, ORS), and rest. Aspirin and ibuprofen (and other NSAIDs) should specifically be avoided, since they can increase bleeding risk in dengue. Most people recover fully at home with this kind of care; severe cases require hospitalization for closer monitoring and, sometimes, IV fluids.

Since there's no widely available vaccine or cure, prevention is genuinely the most powerful tool, and it comes down to mosquito control: empty or cover standing water around the home (buckets, old tires, water tanks, plant trays — anywhere water can collect for more than a few days), use mosquito repellent on exposed skin, wear long sleeves and pants especially during the mosquito's peak biting times (roughly two hours after sunrise and two hours before sunset), and use screens on windows and doors or a mosquito net, especially if someone in the household already has dengue.

This is also a community effort, not just a household one — mosquito breeding sites near a home are a significant risk factor regardless of how careful that one household is, which is why local clean-up drives and supporting municipal fumigation and drainage efforts genuinely matter for everyone's risk, not just the individual participating.

If you or a family member has dengue, staying somewhere with screened windows or under a mosquito net during the illness genuinely matters — it isn't just for the patient's comfort, it prevents mosquitoes from biting an infected person and then spreading the virus further to others nearby.

A small proportion of dengue cases progress to severe dengue, and this is where prompt recognition genuinely saves lives. Warning signs to watch for, usually appearing as the initial fever starts to come down, include: severe abdominal pain, persistent vomiting, rapid or difficult breathing, bleeding gums or nose, blood in vomit or stool, and unusual tiredness or restlessness. These are not symptoms to wait out — they mean it's time for medical evaluation, not more rest at home.
