COVID-19 Update: Almost Every Case Worldwide Emerges From Delta Strain

First detected in India in late 2020, the COVID-19 variant known as Delta now accounts for almost every infection globally, the World Health Organization stated on Tuesday.

The coronavirus variant is known for its transmissibility. Scientists in the U.K. have stated that the Delta variant is between 40% and 60% more transmittable than the Alpha variant, which was first recognized in the U.K. 

While cases continue to surge throughout Europe, WHO technical lead on COVID-19 Maria Van Kerkhove said infections within the continent were responsible for around 60% of the more than 3 million new cases reported globally last week.

Vaccinated individuals generally have mild symptoms if they contract the Delta variant.

“Where Delta is present, Delta takes over,” Van Kerhove said. “[It] is really the dominant one."
