Covid-19 Delta variant is 40 to 60% more contagious than the historic strain and likely to double up the hospitalization hazard and severe disease, a British study found.

A British study published this Saturday in The Lancet Infectious Diseases states people infected by the Covid-19 Delta variant are two times more likely to get hospitalized than with the historic strain, the Alpha variant. It is already common knowledge that the Delta variant is 40 to 60% more contagious, but data on its seriousness are lacking.

The study authors assessed data from about 43,000 Covid cases in England between March 29 and May 23 and show patients are always younger, the average age being 29 against 31 for the Alpha variant. According to their investigations, the risk of being checked in at the hospital is multiplied by 2.26 with the Delta variant. Throughout the study, with the outbreak of this new variant, 75% of the patients were not vaccinated, and about a quarter of the remaining cases recently received one dose. Only 1.8% of the contamination cases were fully vaccinated.
