Bengaluru has witnessed a sharp decline in dengue cases this year, with official figures showing a 55 per cent reduction during April and May compared to the same period last year.

According to health department data, the city recorded 193 dengue cases during April and May 2026, significantly lower than the 429 cases reported during the corresponding months in 2025.

The downward trend has continued into June, with only 42 cases reported so far. In comparison, the city recorded 489 dengue cases during the entire month of June last year.

Prevention efforts show results

Health officials attribute the decline to intensified awareness campaigns, source reduction measures and regular fumigation drives conducted across the city.

Dr Syed Sirajuddin Madni, Chief Health Officer of the Greater Bengaluru Authority (GBA), said ASHA workers have been actively visiting households to educate residents about dengue prevention and eliminate mosquito breeding sites.

Officials noted that areas such as Mahadevapura, which had previously reported high dengue incidence, have shown notable improvement in controlling mosquito populations.

Doctors urge continued vigilance

Despite the encouraging figures, health experts cautioned against complacency, particularly with the monsoon expected to intensify in the coming weeks.

Doctors warned that stagnant water collecting in flower pots, coconut shells, construction sites and low-lying areas could create ideal breeding conditions for mosquitoes and lead to a rise in cases from July onwards.

Medical professionals said hospitals are currently reporting very few dengue admissions and no signs of a major outbreak.

Other monsoon illnesses on the rise

While dengue cases remain under control, doctors have reported an increase in viral fevers, upper respiratory tract infections and influenza-like illnesses.

Experts also cautioned that waterborne diseases such as typhoid, hepatitis A and gastroenteritis tend to increase during the monsoon season. Cases of leptospirosis may also occur following exposure to contaminated water.

Health officials have urged residents to maintain clean surroundings, avoid water stagnation and seek timely medical attention if symptoms develop.
