Delhi recorded 98 new dengue cases in the week ending 3 October 2026, taking the year’s total to 695, according to the Municipal Corporation of Delhi’s weekly vector-borne disease report. September saw 286 cases, the highest monthly count this year, after 90 cases in August. Before September, monthly counts had stayed below 100.
Malaria and chikungunya are also being reported. Malaria had 23 new cases in the first week of October and 266 so far this year, with September’s 124 the highest monthly count. Chikungunya had two new cases, for a total of 29. No deaths from dengue or malaria have been reported in Delhi in 2026, the report said.
The civic body said its domestic breeding checkers have made more than 3.18 crore household visits this year and found mosquito breeding in more than 1.89 lakh households. It has issued 1,32,172 legal notices, started 20,882 prosecutions and collected Rs 29.70 lakh in penalties.
Doctors and officials warn that the end of the monsoon does not automatically end the risk, because standing water in coolers, buckets, flower pots and tanks continues to breed mosquitoes. Residents are advised to empty and clean water containers regularly, keep tanks and drums covered, use repellents and nets, and wear full-sleeved clothing.
People with sudden high fever, severe headache, body or joint pain, nausea, rash or unusual bleeding should see a doctor and avoid self-medicating. The figures here are from the report published on 7 October, and later weekly numbers may be higher.
