Chennai Fever Surge: Dengue & Flu Overlap Stirs Health Alert
21 Oct
Summary
- 15-25% of patients have overlapping dengue and influenza infections.
- Fever cases are rising in Chennai, exacerbated by monsoon rains.
- Doctors advise early consultation for fevers lasting over three days.

Health officials in Chennai are reporting a notable increase in fever cases, with dengue and influenza co-circulating. This surge is particularly concerning as the city experiences heavy monsoon rainfall, increasing the risk of infectious diseases.
Doctors observe that between 15% and 25% of patients present with symptoms of both dengue and influenza, leading to fevers that can persist for 10 to 12 days. Some dengue patients are exhibiting unusual symptoms such as hepatitis or confusion, though recoveries are generally positive.
Government physicians have noted a spike in fevers accompanied by low platelet counts, a condition often associated with dengue or chikungunya. While mortality rates are low, mixed tropical infections are being treated proactively. Testing for specific infections is not standard in government facilities.
Consultants advise that individuals with high-grade fevers should seek medical attention by the third day if symptoms do not subside. Prompt treatment is key, as delayed visits can lead to dehydration and organ dysfunction. For children, home management with paracetamol is an option if they are active and eating, but warning signs like lethargy or vomiting necessitate immediate medical help.
Preventative measures include avoiding waterlogging to curb mosquito breeding and ensuring food safety during the rainy season, as gastroenteritis and typhoid-like infections are common. Flu vaccinations are recommended, though a shortage of the trivalent vaccine has been noted, with only quadrivalent vaccines readily available.
