What should you know about dengue platelet count?

Platelets help blood clot. Dengue can temporarily reduce their number because the infection affects blood-forming and circulating cells. A single result does not show the whole clinical picture: clinicians also consider whether the count is falling or recovering, the haematocrit, bleeding symptoms, blood pressure, urine output, and ability to drink.

A low count does not automatically mean severe dengue, while a count that is not very low does not remove the need to watch for warning signs. Fever may settle as the illness enters a more closely monitored phase.

Follow the testing and review schedule given by your clinician. Drink fluids regularly if you can, rest, and record fever, vomiting, urine output, bleeding, and new pain. Use only medicines recommended for you; avoid aspirin and ibuprofen unless a clinician specifically says otherwise, because they can increase bleeding risk. Do not start supplements or herbal products to change the count without medical advice.

Seek urgent medical help for bleeding from the nose or gums, blood in vomit, urine, or stool, black stool, severe abdominal pain, repeated vomiting, unusual sleepiness or agitation, breathing difficulty, faintness, cold or clammy skin, or very little urine. Easy bruising can occur, but rapidly spreading bruises or any bleeding should be assessed promptly.

Ask what your current count and trend mean, when the next blood test is due, which symptoms should trigger emergency care, how much fluid is suitable for you, and which pain relievers or other medicines you should avoid.
