Covid 19 latest update

Fighting against the ‘Delta’ variant of coronavirus requires a vaccine, plus an infection prevention and control strategy. Even in populations with high uptake of vaccinations, findings of a new study have been revealed. The survey conducted in two Delhi hospitals found that vaccination prevents the severity of the viral attack. There have been cases of breakthrough infection, and that there is also a potential risk of onward transmission to potentially very vulnerable people. The study was conducted by researchers from the INSACOG consortium, CSIR, and National Centre for Disease Control.

The researchers analyzed data on 113 breakthrough infections among health workers.

The researchers analyzed data on 113 breakthrough infections among health workers. It was analyzed by constructing probable transmission networks from epidemiological and virus genome sequence data. They use a suite of computational approaches.
Among known cases, they identify a high probability that doubly-vaccinated individuals transmitted SARS-CoV-2 and potential points of virus transmission between individuals who had received two doses of vaccine. The study highlighted the need for ongoing infection control measures even in highly vaccinated populations.

The study’s findings assume significance as increasing complacency is setting in among people, especially in those who are fully vaccinated. It says that though vaccines remain effective against severe disease, breakthrough infections are a reality. Experts highlight the need for infection control measures even in highly vaccinated populations and mask-wearing by individuals.
