Navi Mumbai Reports Lower Malaria, Suspected Dengue Cases
Navi Mumbai saw fewer malaria and suspected dengue cases in 2026 than in 2025.
There were 23 malaria cases this year, compared with 32 last year.
Suspected dengue cases dropped from 669 to 194.
However, suspected dengue does not always mean a person definitely has dengue.
NMMC said an NS1 test only gives an indication of a possible viral infection.
Suspected samples are sent to a special laboratory in Pune for confirmation.
Only cases confirmed by that laboratory are officially counted as dengue.
Mosquito-related illnesses still increased during the rainy monsoon months.
July had the highest number of malaria and suspected dengue cases in 2026.
Navi Mumbai recorded 23 malaria cases from January 1 to August 20, 2026, compared with 32 during the same period in 2025.
Suspected dengue cases fell to 194 in 2026 from 669 in 2025.
Only one of 82 suspected dengue samples sent for confirmation in 2026 tested positive, compared with three of 138 samples in 2025.
NMMC said a positive NS1 antigen test alone does not confirm dengue; samples require confirmation by the National Institute of Virology in Pune.
Malaria and suspected dengue cases increased during the monsoon, with July recording 10 malaria cases and 69 suspected dengue cases in 2026.

Quotes
NMMC official
An official from the Navi Mumbai Municipal Corporation explaining the difference between NS1 results and confirmed dengue cases.
“Many people consider NS1 to be confirmation of dengue, which is not correct. NS1 is basically an indication of a viral infection and should not be considered dengue on its own. Suspected samples are sent to NIV, Pune, and only after confirmation are they counted as dengue cases.”
