Dengue cases rise in Chennai, 1,290 people affected in September
Dengue cases in Chennai have more than doubled in September, with 1,290 people affected. Health officials are on high alert as the seasonal surge continues.

The mosquito-borne disease is spreading rapidly across the Tamil Nadu capital, with dengue cases in Chennai seeing a massive spike throughout the month of September. According to the Tamil Nadu Health Department, a total of 1,290 individuals were diagnosed with the virus in September alone.
This recent surge represents a significant jump compared to the previous month. In August, the city reported 605 cases, meaning the infection rate has more than doubled in just thirty days. The intensity of the outbreak was particularly evident on September 30, when 72 new cases were recorded in a single day.
Hospitals on high alert to manage seasonal surge
As the numbers climb, medical facilities are bracing for a continued seasonal influx of patients. In Thoothukudi, the Government Medical College Hospital has taken proactive steps to ensure they can handle the rising demand. The facility has established specialized wards specifically for dengue management.
Key preparations at the hospital include:
- Dedicated Wards: Separate units for adults and children to manage different patient needs.
- Bed Allocation: Approximately 60 beds have been reserved for adults and 40 beds for paediatric patients.
- Safety Measures: All designated beds are isolated and equipped with mosquito netting to prevent secondary transmission within the hospital.
- Resource Readiness: Sufficient stocks of IV fluids, essential medicines, plasma, and blood components are currently available.
Dr. R. Padmanabhan, the Medical Superintendent, confirmed that the hospital is fully prepared to manage the surge and is ready to increase bed capacity and deploy more medical resources if admissions continue to climb.
Understanding the three phases of Dengue
Medical experts are urging the public to understand the progression of the disease to avoid life-threatening complications. Dr. Padmanabhan explained that dengue typically moves through three distinct stages:
- The Febrile Phase: Characterized by a sudden, high-grade fever.
- The Critical Phase: Usually occurring around the fifth or sixth day after the fever subsides. During this stage, patients may suffer from extreme tiredness, muscle pain, vomiting, and severe abdominal pain.
- The Recovery Phase: As the body begins to stabilize.
A major concern during the critical phase is the rapid drop in platelet counts, a condition known as thrombocytopenia. This can lead to dangerous internal or external bleeding from the nose, mouth, or urinary tract, making close medical supervision vital.
How to prevent mosquito breeding at home
Health officials are emphasizing that community action is just as important as medical treatment. To reduce the transmission of the virus, citizens are advised to eliminate potential breeding grounds for mosquitoes.
"Whenever you find stagnant water inside or outside your house, make sure it is removed," Dr. Padmanabhan advised. He specifically highlighted common household areas where water can collect, such as:
- Flower pots
- Behind refrigerators
- Any containers used for storing clean water (which must be kept tightly covered)
Health experts urge anyone experiencing high-grade fever to seek immediate medical evaluation rather than delaying treatment, as early intervention is key to managing the disease safely.
