As many as 2,760 cases were recorded in areas not falling under the three corporations.

At least 21 deaths due to dengue were reported last year from various city hospitals, including nine at AIIMS, though the official figure of the civic bodies was 10. Seventeen deaths, suspected to be due to malaria, were also reported by civic bodies last year.

At least 15 fatalities were reported last year at various city hospitals due to complications triggered by chikungunya, though civic authorities kept the death tally at zero. One of the worst outbreaks of chikungunya was in 2016 when 12,221 cases were reported till December 24. Of these, 9,749 were confirmed.
