Project #81:
Analysis of the relative severity of the SARS-CoV-2 Delta variant compared to the Alpha variant

  • Type: Research
  • Topic areas: COVID transmission/prevalence/non-pharmaceutical prevention

The SARS-CoV-2 Delta variant first emerged in India in late 2020. The Delta variant became the dominant circulating form of SARS-CoV-2 in the UK by summer 2021.

This study considered the feasibility of an analysis to estimate the relative severity of the SARS-CoV-2 Delta variant compared to the previously circulating forms of the virus.
