Of all the COVID variants, Delta is the deadliest one, a new study has revealed. Five different coronavirus variants were studied for the research that include Alpha, Delta, and three others that emerged before Alpha.
The scientists tried to understand if hosts, that is, humans infected by the virus, react differently to different SARS-CoV-2 variants, it said adding, “In the last almost three years, there have been many SARS-CoV-2 variants spreading across the world.
But their outcome has varied greatly, with the Delta variant being the deadliest." The study has been published in Microbiology Spectrum journal.
Explaining this, the researchers said, the immune system could not produce the defence molecules against the Delta variant as effectively as the other variants.
