Delta variant outplays other variants of concern

The Delta variant of Covid-19 is the globally dominant variant circulating around the world, out-competing the alpha, beta and gamma variants, Maria Van Kerkhove, the World Health Organisation’s technical lead on Covid-19 told reporters.

The delta variant has also become more fit and transmissible over time and is now actively replacing all other Covid-variants in circulation, Van Kerkhove added.

“Less than 1% each of Alpha, Beta and Gamma are currently circulating. It’s really predominantly Delta around the world,” Maria Van Kerkhove, the World Health Organisation’s technical lead on COVID-19, was quoted saying during a WHO social media live interaction.

According to Centers for Disease Control and Prevention (CDC), the Delta variant is highly contagious, more than 2x as contagious as previous variants. Some data suggested that the Delta variant might cause more severe illness than previous variants in unvaccinated people.
