Hard-won gains being lost as Delta variant spreads - WHO

The world is at risk of losing hard-won gains in fighting COVID-19 as the highly transmissible Delta variant spreads, but WHO-approved vaccines remain effective, the World Health Organization said on Friday.

The US Centers for Disease Control and Prevention (CDC) has described the Delta variant of the coronavirus as being as transmissible as chickenpox and cautioned it could cause severe disease, the Washington Post said, citing an internal CDC document.

COVID-19 infections have increased by 80% over the past four weeks in most regions of the world, WHO director-general Tedros Adhanom Ghebreyesus said. Deaths in Africa - where only 1.5% of the population is vaccinated - rose by 80% over the same period.

"Hard-won gains are in jeopardy or being lost, and health systems in many countries are being overwhelmed," Tedros told a news conference.

The Delta variant has been detected in 132 countries, becoming the dominant global strain, according to the WHO.
