Dengue at home: warning signs, platelet myths and when to go to hospital

In short: Most people with dengue recover at home with rest, fluids and paracetamol. The risky time is the day or two after the fever falls: go to hospital at once for belly pain, repeated vomiting, bleeding, drowsiness, fast breathing or cold, clammy skin, whatever the platelet count says.

Dengue season is not over. Delhi recorded 98 new cases in the first week of October, taking its 2026 total to 695, after its highest month of the year in September (286 cases). West Bengal logged nearly 1,100 cases in the same week and 10,177 so far this year. Across India, the Health Ministry told Parliament that 1,13,440 cases and 94 deaths were reported from January to November 2025, with Tamil Nadu, Maharashtra and Kerala reporting the most.

Most people who catch dengue get better at home. The ones who get into trouble are often the ones whose families were watching the wrong thing: the platelet count, rather than the warning signs. This guide explains how the illness unfolds, what to do at home, which popular remedies to skip, and the exact signs that mean you should go to hospital.

How dengue unfolds, day by day

Dengue is a virus spread by Aedes mosquitoes, which bite mainly during the day. According to WHO, symptoms usually start 4 to 10 days after the bite and last 2 to 7 days. Many infections cause no symptoms at all.

Doctors describe the illness in three phases:

Phase	Usual timing	What happens
Fever	Usually 2 to 7 days	High fever, severe headache, pain behind the eyes, body and joint pain, nausea, rash
Critical	Starts as the fever falls, lasts 24 to 48 hours	In a small number of people, fluid leaks out of the blood vessels. Watch for the warning signs below.
Recovery	After the critical phase	Leaked fluid is reabsorbed and platelets climb. Tiredness can last weeks

The most important line in that table is the middle one. The US Centers for Disease Control and Prevention (CDC) notes that in the critical phase, leaking plasma can lead to severe disease within a few hours, even though most patients seem to be improving. A family sees the fever break and relaxes, just as the dangerous day begins. Keep watching for at least two days after the fever settles.

WHO adds that a previous dengue infection raises the risk of severe dengue the next time, so someone who has had dengue before should be extra careful. Most people recover within one to two weeks, though the tiredness can last several weeks.

Who needs extra care

India’s national dengue guideline, published by the National Center for Vector Borne Diseases Control (NCVBDC) in 2023, lists the people at higher risk of severe dengue. They should see a doctor early, and the doctor may advise admission sooner:

• infants and children under 10, especially if undernourished;
• adults over 65;
• pregnant women, and women who are menstruating or have abnormal vaginal bleeding;
• people with obesity;
• people with diabetes, high blood pressure, heart, lung, kidney or liver disease;
• people with thalassaemia, G6PD deficiency or other blood disorders, or peptic ulcers;
• anyone on long-term steroids or anti-inflammatory painkillers.

Caring for dengue at home

If a doctor has seen you and says you can be treated at home, the national guideline and WHO’s 2025 clinical guideline agree on the basics.

Fluids come first

• Drink often, in small amounts, especially if you feel sick. WHO says water should be the main drink, and oral rehydration solution (ORS) is a practical way to replace salts. Coconut water, soups, buttermilk or lassi and rice water (kanji) all count.
• Avoid fizzy soft drinks. Both guidelines advise against them; WHO notes that very sugary drinks can push up blood sugar during the illness.
• Count the toilet trips. WHO says enough fluid should mean passing urine at least four to six times a day. Fewer than that, or very dark urine, means you need more fluid or a doctor’s review.
• Keep a simple log. WHO suggests measuring what you drink with a cup and totalling it daily. A notebook with the time, the drink, the amount, each urination and the temperature is enough, and it helps the doctor enormously at follow-up.

Fever and pain: paracetamol only

• Paracetamol is the medicine to use. The national guideline advises it when the temperature is above 100°F, at 10 mg per kg of body weight per dose, no more often than every six hours, and never more than 4 g a day for an adult. For children, follow the doctor’s dose for their weight.
• Do not take ibuprofen, aspirin, diclofenac, naproxen or other anti-inflammatory painkillers. WHO makes a strong recommendation against them in suspected dengue, whatever the severity, because they add to the risk of bleeding. Check combination cold and pain tablets for these ingredients too.
• Sponge with lukewarm water on the forehead, armpits and limbs if the fever is high. Do not use ice-cold water.
• No injections “for quick relief”. The national guideline advises against intramuscular injections in dengue because of the bleeding risk.

Things that do not help

• Steroids. WHO advises against corticosteroids for dengue, in both mild and severe illness.
• Antibiotics. Dengue is a virus. Antibiotics do nothing for it, may cause side effects and add to antibiotic resistance. Our guide to antimicrobial resistance in India explains why that matters.
• Rest is not optional. Bed rest is part of the national guideline’s home-care advice. Do not go back to work, school or the gym the day the fever breaks.

The platelet trap

Almost every Indian family with a dengue patient ends up staring at the platelet count. It falls, everyone panics, and someone starts calling blood banks. Here is what the evidence actually says.

The number does not predict bleeding well. India’s national guideline states plainly that platelet counts are unreliable for predicting bleeding. What makes dengue dangerous is mostly fluid leaking out of the blood vessels, which a platelet count does not measure. That is why doctors also watch the haematocrit (how concentrated the blood is), blood pressure, pulse and urine output.

Preventive platelet transfusions do not prevent bleeding. In a randomised trial published in The Lancet, 372 adults with dengue and platelet counts of 20,000 per microlitre or lower were given either platelet transfusions plus usual care, or usual care alone. Bleeding occurred in 21% of the transfusion group and 26% of the comparison group, a difference that could have been chance. The transfusion group had 13 adverse events against two, including a severe allergic reaction, a transfusion-related lung injury and fluid overload. WHO’s 2025 guideline now advises against preventive platelet transfusion in hospitalised patients with counts below 50,000 who are not bleeding.

Transfusions still have a place. Doctors give blood or platelets when a patient is actually bleeding heavily or is unstable, and that is a decision for the treating team. If your doctor says a transfusion is not needed, that is usually good medicine, not neglect.

Platelets recover on their own. CDC describes platelet counts climbing in the recovery phase, as the body reabsorbs fluid. A low count that is starting to rise, in someone who is eating, drinking and passing urine, is usually a good sign.

Papaya leaf, kiwi and goat milk

Papaya leaf juice is the most popular home remedy for dengue in India. A 2019 systematic review in BMC Complementary and Alternative Medicine looked at nine controlled trials, six of them from India. Most reported that platelet counts rose a little faster with papaya extract, but the evidence was rated low quality with a high risk of bias, doses varied, and no trial measured what matters: shock, serious bleeding or death. The authors concluded that routine use “cannot be recommended”.

The practical risk is that bitter raw juice can bring on nausea and vomiting, which is the last thing a dengue patient needs, and that time spent chasing a remedy is time not spent drinking fluids or watching for warning signs. No remedy, including kiwi, dragon fruit, goat milk or giloy, has been shown to prevent severe dengue. If you want to try something, tell your doctor first, and never let it replace fluids or delay a hospital visit.

Getting the right test at the right time

Fever in October could be dengue, malaria, chikungunya, typhoid or something else, and the treatment differs. See a doctor for any high fever rather than guessing.

The national guideline matches the dengue test to the day of illness:

• NS1 antigen test: for blood taken on days 1 to 5 of fever.
• IgM antibody test: for blood taken after day 5.

So a negative NS1 test on day 6 does not mean you do not have dengue. The national programme also says rapid card tests vary from batch to batch, and does not recommend them for confirming dengue or guiding treatment; ELISA tests in a laboratory are preferred. Your doctor will usually repeat a complete blood count every day or two during the critical days.

Dengue or chikungunya? Both are spread by the same mosquitoes and start with sudden fever. WHO notes that chikungunya typically causes severe joint pain that can last weeks, months or even years. Because they are easy to confuse, WHO advises taking paracetamol, not anti-inflammatory painkillers, until dengue has been ruled out.

Red flags: when to go to hospital

Go to hospital the same day, without waiting for the next blood test, if the person with dengue has any of these. They are the warning signs listed by WHO and India’s national guideline, and they often appear as the fever comes down:

• severe pain in the abdomen, especially on the upper right side, or pain when the belly is touched;
• vomiting again and again, or being unable to keep fluids down;
• bleeding from the gums or nose, blood in vomit, black tarry stools, or new red spots or patches on the skin;
• passing very little urine, far less often than usual;
• fast or difficult breathing;
• drowsiness, confusion, restlessness or unusual irritability, or a child who is floppy or will not play;
• cold, pale or clammy hands and feet;
• intense thirst or extreme weakness.

Call 112 or go to an emergency department immediately if the person is very drowsy or hard to wake, is breathing with great difficulty, has heavy bleeding, or feels cold and clammy with a weak pulse. These can be signs of dengue shock, which needs urgent hospital treatment with fluids.

See a doctor promptly, the same day or next morning, for any high fever in a baby, a pregnant woman, an older adult or someone with a long-term illness. In this season, any high fever deserves a doctor’s visit.

Severe dengue is treatable when it is caught early. WHO’s 2025 guideline sets out how hospitals manage it, using careful fluid treatment guided by simple bedside checks such as how quickly colour returns to a pressed fingertip. The aim of watching at home is to get the patient there in time.

Stopping the next bite

The Aedes mosquito breeds in clean, still water close to where people live. It bites mainly in the daytime, so a bed net at night is only part of the answer. CDC’s advice translates easily to Indian homes:

• Once a week, empty, scrub, cover or throw out anything holding water: desert coolers, flower-pot saucers, buckets, drums, old tyres, the tray under the fridge, coconut shells and plastic on the roof. WHO advises covering, emptying and cleaning household water containers every week.
• Cover water tanks and storage drums with tight lids.
• Use a repellent with DEET, picaridin (icaridin), IR3535, oil of lemon eucalyptus or PMD, following the label. Do not use oil of lemon eucalyptus or PMD on children under 3. Adults should put repellent on their own hands first and then on a child’s face, avoiding the eyes, mouth and hands. If you use sunscreen, put it on first.
• Cover up with loose, long sleeves and full-length trousers, and use mosquito netting over cots, strollers and baby carriers.
• Fit screens on windows and doors where you can.
• Protect the patient too. WHO says a person with dengue can pass the virus to mosquitoes from about two days before symptoms start until about two days after the fever ends, so keep them under a net and use repellent.

Our guide to El Niño and your health explains how hotter, wetter seasons give mosquitoes more chances to breed.

What about a vaccine?

There is news here. India’s drugs regulator approved Takeda’s dengue vaccine, Qdenga, in July 2026, for people aged 4 to 60. It is given as two injections three months apart, and the company must run a safety and effectiveness study in India after launch. At the time of approval, its launch date, price and any use in government programmes had not been announced. WHO currently recommends Qdenga for children aged 6 to 16 in places with high transmission.

India’s own vaccine, DengiAll, developed by Panacea Biotec with ICMR, began a phase 3 trial in August 2024 with more than 10,335 adults at 19 sites in 18 states and union territories. Ask your doctor whether a vaccine makes sense for your family once it is available. In the meantime, no vaccine changes the advice for someone who has dengue now.

The bottom line

Most dengue is mild and gets better with rest, fluids and paracetamol. Watch the person, not just the platelet count: the danger window is the day or two after the fever falls. Keep a simple log of drinks, urine and temperature, avoid anti-inflammatory painkillers, injections and steroids, and go to hospital straight away for belly pain, repeated vomiting, bleeding, drowsiness, fast breathing or cold, clammy skin. Then empty the cooler and the flower-pot saucers, so nobody else in the house is next.

This article is general health information, not medical advice. If you or a family member has a fever, see a doctor. In an emergency, call 112 or go to the nearest hospital.

Frequently asked questions

At what platelet count should a dengue patient be admitted?

There is no single number. India's national dengue guideline says platelet counts are unreliable for predicting bleeding, and doctors decide on admission from warning signs, blood pressure, hydration, the haematocrit trend and risk factors such as pregnancy, infancy, old age or diabetes. A falling count is a reason to stay in close touch with your doctor, not a reason to panic or demand a transfusion.

Does papaya leaf juice cure dengue?

No. A 2019 systematic review of nine small trials found platelet counts rose a little faster with papaya extract, but the evidence was low quality and none of the trials looked at shock, serious bleeding or death. The authors concluded that routine use cannot be recommended. Raw leaf juice can also bring on vomiting, which makes it harder to keep fluids down.

Can I take ibuprofen or aspirin for dengue fever?

No. WHO strongly recommends against anti-inflammatory painkillers such as ibuprofen, diclofenac, naproxen and aspirin in suspected dengue, because they raise the risk of bleeding. Use paracetamol at the dose your doctor or the label gives, and never more than 4 g a day for an adult.

Which dengue test should I get, and when?

India's national guideline matches the test to the day of fever: the NS1 antigen test for samples taken on days 1 to 5, and the IgM antibody test after day 5. A negative NS1 late in the illness does not rule dengue out. Your doctor will usually also order a complete blood count, and may test for malaria.

Is there a dengue vaccine in India?

India's drugs regulator approved Takeda's Qdenga in July 2026 for people aged 4 to 60, given as two doses three months apart, but its launch date and price had not been announced. India's own vaccine, DengiAll, is still in a phase 3 trial. Neither changes what to do if you have dengue now.
