From infection rates to vaccine efficacy: how Omicron differs from Delta – The National
The detection of the Omicron variant of Covid-19 in Botswana and South Africa in November 2021 represented another milestone in the pandemic.
Delta, which was first detected in India the previous year, had become the dominant form of Sars-CoV-2 in many countries because of its ease of spread.
But Omicron was able to pass between people even more readily, and this meant that it took over as the most common variant and caused huge surges in cases in many parts of the world.
