As mosquito-borne diseases remain a major public health concern during the monsoon, specialists at Apollo Spectra Hospital, Bengaluru, are urging people to focus on early diagnosis, timely treatment and preventive measures on the occasion of World Mosquito Day.

Doctors said infections such as dengue, malaria and chikungunya tend to increase during the monsoon as water stagnation and favourable weather conditions support mosquito breeding. 

In Bengaluru, recent conditions, including 35 mm of rainfall over two weeks, humidity of up to 83% and temperatures ranging from 23°C to 29°C, have created favourable conditions for mosquito activity.

Apollo Spectra Hospital reported an 11.8% increase in dengue testing and consultations compared with the corresponding period in 2025, with 14.5% of those tested returning positive. 

Of the patients diagnosed with dengue, 80% required hospitalisation or close monitoring because of concerns including dehydration, falling platelet counts and other warning signs.

Doctors also observed that many patients sought medical attention only after three to five days of persistent fever, potentially increasing the risk of complications. Symptoms associated with mosquito-borne infections include high fever, severe body pain, headache, fatigue, rashes, vomiting and weakness.

Dr. Ravi Kesari, MBBS, MD (Internal Medicine), Apollo Spectra Hospital, Bengaluru, said, “One of the biggest concerns is that many mosquito-borne diseases initially resemble a common viral fever, leading patients to delay testing and medical evaluation.”

“Persistent fever, severe body pain, vomiting, rashes, or unusual bleeding should never be ignored. Early diagnosis and timely monitoring are critical, particularly in dengue, where complications can develop rapidly if treatment is delayed,” Dr. Kesari added.
