Thirty-two cases of dengue have also been reported in the last four months, according to a municipal report released today.
As many as 4,431 cases of dengue were reported till the end of 2016, according to the report by the South Delhi Municipal Corporation which tabulates the data on behalf of all municipal corporations in the city.
Out of the 86 chikungunya cases reported till April 29, 19 of these were recorded last month, while 34 were diagnosed in March. 20 cases were detected in January and 13 in February.
Six cases of dengue were reported in January, four in February, 11 in March and 11 in April. Lt Governor Anil Baijal on April 29 had directed Delhi government-run LNJP Hospital to keep beds ready for dengue and chikungunya patients in the event of an outbreak of the vector-borne diseases in the city.
Till January 14, only two chikungunya cases were reported, while no dengue case had been reported till then.
Chikungunya and dengue cases in the national capital had tapered off by December first week last year ending the vector-borne disease season in the city that witnessed its worst chikungunya outbreak in the last 10 years, but cases are still being registered, prompting authorities to go for early preparedness.
The municipal authorities had in early March called an all-hands workshop on prevention and control of vector-borne diseases to finalise a comprehensive action plan for combating the menace in the coming season.
The Lt Governor on March 23 had held a review meeting with the three municipal commissioners on preparations for combating vector-borne diseases in the city in the wake of cases of vector-borne diseases still being reported.
At least 15 fatalities were reported last year at various hospitals in the city due to complications triggered by chikungunya though the civic bodies have kept the death tally at zero.
At least 21 deaths due to dengue were reported last year at various hospitals, including nine at AIIMS, though the official tally of the SDMC stood at 10.
Seventeen suspected deaths in 2016 due to malaria were also reported by the civic bodies.
In one of the worst outbreak, a total of 12,221 chikungunya cases were reported in Delhi till December 24, 2016 out of which 9,749 were confirmed.
The season for the vector-borne diseases begins from mid-July and generally lasts till November-end.
