New Delhi, October 3

Data announced by the municipal corporations disclosed that at least 5,293 people have been afflicted with chikungunya in the national Capital this season, with an over 43 per cent rise in the number of reported cases of the vector-borne disease in the last one week alone.

Out of the total cases recorded till October 1, over 500 of them have been reported in the areas falling under the North Delhi Municipal Corporation (NDMC), an official of the civic body said .

Nearly 3,700 cases were reported in Delhi till September 24, according to SDMC, which tabulates the data for the disease in the national Capital on behalf of all the civic bodies here.

Among the three corporations, 515 cases in areas under the NDMC, 498 under the South Delhi Municipal Corporation and 172 under the East Delhi Municipal Corporation have been reported this season.

At least 15 fatalities due to complications triggered by the disease have been reported at various hospitals in the city though the civic bodies have kept the death tally at zero.

Delhi and other parts of north India are facing a spike in chikungunya cases after nearly 10 years, and experts had earlier conjectured that the rising number of cases could have been due to “evolution” in the chikungunya virus (CHIKV).

However, doctors at AIIMS have identified the genotype of the CHIKV which is the same as the one that caused the 2006 outbreak of the vector-borne disease.

“We have identified the genotype of the virus--East Central South African--and sent the report to the National Vector-Borne Disease Control Programme (NVBDCP). It is the same genotype that was in circulation in 2006 outbreak,” Lalit Dar of Department of Microbiology at AIIMS had earlier said.

According to municipal data, the last time the number of affected people had reached three-figure mark was in 2011.
