3 charts show how far Covid delta variant has spread around the world
More than one year into the Covid-19 pandemic, the world is grappling with a highly transmissible delta variant that has caused a renewed surge in infections in countries from the U.K. and the U.S., to those in Africa and Asia.
The delta variant, which was first detected in India last October, has been found in more than 130 countries globally, according to the World Health Organization.
Delta is the most transmissible variant of the coronavirus that first emerged in China in late 2019, said Dr. Maria Van Kerkhove, an epidemiologist and technical lead for Covid-19 at the WHO.
“The virus itself, as it starts, is a dangerous virus, is a highly transmissible virus. The delta variant is even more so — it’s doubly more transmissible than the ancestral strain, it’s 50% more transmissible than the alpha strain,” she said at a WHO media briefing last week.
The alpha variant was first detected in the U.K.
