People infected with the delta variant of SARS-CoV-2 are twice as likely to be hospitalized as those infected with the alpha variant. Scientists conducted a study of more than 40 thousand cases of the disease in England from March 29 to May 23, 2021. The results are published by The Lancet Infectious Diseases.
It was also found that the risk of going to the hospital for emergency care or hospitalization within 14 days after infection with the delta variant is one and a half times higher compared to the alpha variant.
“This study confirms previous findings that people infected with the delta variant are more likely to need hospitalization than people with the alpha variant. It is worth noting that most of those hospitalized were not vaccinated, ”explains Gavin Dabrera, one of the study’s lead authors and consultant epidemiologist for the National Infections Service of England.
The delta variant was first registered in India in December 2020. Early research showed that it is 50% more infectious than the alpha variant of COVID-19, which was first identified in Kent, UK.
