Continuing COVID-19 outbreaks across India are attributable to the Delta variant, a susceptible population and reduced vaccine effectiveness in blocking transmission, the INSACOG has said. It is a genome sequencing government consortium of laboratories. However, vaccination continues to be very effective in reducing severe disease and death, and public health measures to reduce transmission and inoculation remain critical, the INSACOG stressed in its latest bulletin on August 16.

Delta variant is the major VOC in India at this time. Continuing outbreaks across India are attributable to Delta, a susceptible population, reduced vaccine effectiveness in blocking transmission, and opportunities for transmission,” the INSACOG said.
