Every year, as the monsoon rains ease and standing water collects in streets, rooftops and flower pots, dengue season arrives in Pakistan. If you or a family member has a sudden high fever with body aches, it is natural to worry. The good news is that most people recover fully from dengue with rest, fluids and careful monitoring — but knowing the warning signs can save a life.

What is dengue fever?

Dengue is a viral infection spread by the bite of the Aedes aegypti mosquito, a black-and-white striped mosquito that bites mostly during the day, especially in the early morning and before sunset. It cannot spread directly from person to person. Pakistan sees tens of thousands of confirmed cases in a typical year, with large outbreaks in Lahore, Karachi, Rawalpindi, Islamabad and Peshawar, usually peaking between September and November after the monsoon.

There are four types (serotypes) of the dengue virus. Catching one type gives you immunity to that type only, and a second infection with a different type can sometimes be more severe. This is why the World Health Organization advises that anyone who has had dengue before should be extra careful during outbreak season.

Symptoms of dengue

Symptoms usually appear 4 to 10 days after the mosquito bite. Common symptoms include:

  • Sudden high fever, often 39 to 40 degrees Celsius
  • Severe headache, especially pain behind the eyes
  • Intense muscle, bone and joint pain — the old name was breakbone fever
  • Nausea and vomiting
  • A fine skin rash appearing a few days into the illness
  • Feeling extremely weak and tired

Many people, especially children, have mild or almost no symptoms and mistake dengue for ordinary flu.

Danger signs — go to hospital now

The World Health Organization lists specific warning signs that mean dengue may be becoming severe. Severe dengue usually develops just as the fever is settling, around day 3 to 7 — this is the most dangerous phase, not the recovery, so do not relax too early. Go to a hospital emergency department immediately, or call Rescue 1122, if you notice:

  • Severe belly pain or constant vomiting
  • Bleeding from the gums or nose, blood in vomit or stool, or heavy periods
  • Small red or purple spots on the skin that do not fade when pressed
  • Cold, clammy hands and feet, or restlessness and confusion
  • Difficulty breathing
  • Passing very little urine
  • A rapid drop in platelet count on blood tests

How doctors test for dengue

In Pakistan, dengue testing is widely available in both government and private labs. Your doctor will usually order:

  • Dengue NS1 antigen test — best in the first 5 days of fever
  • Dengue IgM and IgG antibody tests — useful after day 5
  • CBC (complete blood count) — to watch the platelet count and haematocrit, often repeated daily during the illness

During declared outbreaks, many government hospitals in Punjab, Sindh and KP offer free dengue testing and dedicated dengue counters.

Treatment: what actually helps

There is no specific antiviral medicine that kills the dengue virus. Treatment is supportive, and WHO guidance is clear about what helps and what harms:

  • Rest and plenty of fluids — water, ORS, fresh juices, soups and milk. Good hydration is the single most important treatment.
  • Paracetamol is the recommended medicine for fever and pain, taken as advised by a doctor.
  • Avoid aspirin, ibuprofen and other painkillers in the NSAID family unless a doctor specifically prescribes them, because they can increase the risk of bleeding in dengue.
  • Platelet transfusion is only needed in specific situations decided by a doctor — a low number alone does not always require it.

You may hear about papaya leaf juice and other desi remedies for raising platelets. These are part of our culture and many families trust them, but current international evidence does not prove they change the outcome of dengue. If you choose to use them, please do so alongside — never instead of — medical care and daily blood monitoring.

Prevention

Because the Aedes mosquito breeds in clean, still water, prevention starts at home:

  • Empty and scrub water containers, coolers, pot plates and roof tanks weekly
  • Cover stored water tightly
  • Use mosquito repellent, full-sleeved clothes and window screens
  • Sleep under a net if you are ill, so mosquitoes do not carry the virus from you to others

The WHO-recommended dengue vaccines are used in some countries under specific conditions but are not part of routine practice in Pakistan yet, so mosquito control remains our best protection.

Age-specific notes

  • Children: fever in children can rise quickly and dehydration develops faster. Watch urine output and energy levels closely. Persistent vomiting in a child is a hospital sign.
  • Adults: do not push through work with a dengue fever — rest genuinely matters in the critical phase.
  • Over-60s: older adults and people with diabetes, heart disease or kidney disease have a higher risk of severe dengue and usually need closer monitoring, sometimes admission.
  • Pregnancy: dengue in pregnancy needs hospital-level care. Tell your doctor immediately if you are pregnant and develop fever in dengue season. Fever in pregnancy has many causes, including typhoid — see our typhoid guide.

Frequently asked questions

Dengue mein platelets kitni honi chahiye?

A normal platelet count is roughly 150,000 to 450,000. In dengue, counts often fall below 100,000 and usually recover on their own within a week. Doctors worry more about warning signs and bleeding than the number alone, which is why daily CBC monitoring matters more than any single reading.

Dengue kitne din mein theek hota hai?

Most people recover in 7 to 10 days. The fever phase lasts 2 to 7 days, followed by a critical phase of 24 to 48 hours when complications can appear, then recovery. Full energy may take another one to two weeks to return.

Can dengue happen twice?

Yes. There are four types of dengue virus, and immunity to one type does not protect you from the others. A second infection can sometimes be more severe, so people who have had dengue before should be extra careful with mosquito protection.

Is papaya leaf juice a cure for dengue?

No remedy, including papaya leaf, has been proven to cure dengue in strong scientific studies. Hydration, paracetamol and monitoring remain the evidence-based treatment. If your family uses papaya leaf, use it alongside medical care, not as a replacement.

Dengue test kab karwana chahiye?

If you have fever for more than a day during dengue season, get tested. The NS1 antigen test works best in the first 5 days of fever, and IgM antibody testing after day 5. A CBC alongside helps your doctor track platelets from the start.
