5 silent warning signs dengue is turning severe

Dengue has long been associated with the monsoon season, but that pattern is shifting. Increasingly, infections are being reported during the summer months as well. Because many still believe dengue only occurs in the rainy season, early warning signs are often dismissed as a simple cold.

Experts stress that awareness must extend beyond the monsoon.

Why is dengue appearing in summer?

Dr. L. Sudarshan Reddy, senior consultant physician at Yashoda Hospitals, Hyderabad, explained that climate change is a key factor. Rising temperatures allow dengue‑carrying mosquitoes to survive and spread more easily. “Even a one‑degree Celsius rise can increase the risk of dengue infection by up to 13 per cent,” he noted.

Erratic summer weather — extreme heatwaves followed by sudden rain and humidity — creates ideal breeding conditions, especially in dense urban areas. These changes extend the transmission window and push dengue into regions previously considered low‑risk.

Why can dengue be deceptive?

Dr Reddy emphasised that dengue often mimics other illnesses, appears to improve before worsening, and can become life‑threatening within hours. While dropping platelet counts are a common concern, severe dengue is defined by complications such as fluid leakage, massive bleeding, or organ failure, which may not directly correlate with platelet levels.

Five critical warning signs of severe dengue

According to Dr Reddy, patients should be alert to these symptoms, especially once the fever subsides:

Severe abdominal pain — Persistent stomach pain and inability to consume fluids may signal plasma leakage, fluid buildup, and organ stress.

Bleeding — From gums, nose, urine, stool, or under the skin. Internal bleeding can cause dangerously low blood pressure and organ damage.

Rapid or difficult breathing — Fluid accumulation in the lungs can make breathing hard; any respiratory distress is a medical emergency.

Persistent vomiting and loose stools — Repeated vomiting (three or more times daily) indicates the body is struggling to cope with infection.

Sudden fatigue, restlessness, or irritability after seeming recovery — A false sense of improvement followed by extreme weakness can be a sign of severe dengue.

Bottom line

Dengue is no longer confined to the monsoon. Climate shifts are driving infections into summer, making vigilance essential. Recognising these warning signs early can prevent life‑threatening complications.
