The head of the World Health Organization said the COVID-19 variant first seen in India, also known as the delta variant, is "the most transmissible of the variants identified so far" and that it is now spreading in at least 85 countries.

At a newsbriefing on Friday, WHO director general Tedros Adhanom Ghebreyesus said the United Nationsagency isconcerned about the increasing reach of the delta variant, particularly among unvaccinated populations.

"We are starting to see increases in transmission around the world," Tedros said, adding that "more cases means more hospitalizations ... which increases the risk of death."

WHO has previously said that two doses of the licensed COVID-19 vaccines appear to provide strong protection against the delta variant, but he warned that the lack of access to vaccines in poor countries which have received fewer than two per centof the billion doses administered so far makes them extremely vulnerable.

WHO officials also warned that the unchecked circulation of the coronavirus could lead to the emergence of even more variants.

"The delta variant, the virus, will continue to evolve," said Maria Van Kerkhove, WHO's technical lead on COVID-19.

"Right now our public health and social measures work, our vaccines work, our diagnostics work, our therapeutics work. But there may be a time where this virus evolves and these countermeasures don't."

Canada watching delta variant

In Canada, health officials on Friday similarly expressed concernabout the delta variant, saying itcould lead to a larger-than-expected resurgence in case numbers this fall if it becomes the dominant strain of COVID-19 in the country.

Chief Public Health Officer Dr. Theresa Tamreiterated the importance of keepingpersonal protective measures in place until the country achieves a higher level of vaccination coverage.

The Public Health Agency of Canada also released a chart with guidance on how people should approach various social situations, depending on their vaccination status.

For example, the agencysays that those who are fully vaccinated don't need to wear masks or physically distance while indoors with a small group of other fully vaccinated individuals.

What's happening around the world

As of Friday evening, more than 180.1 million cases of COVID-19 had been reported worldwide, according to the latest numbers from Johns Hopkins University's coronavirustracker.The reported global death toll stood at more than 3.9 million.

InEurope,British officials say there were only 28 reported coronavirus cases among tens of thousands of people who attended mass-audience test events, including soccer games, a snooker championship, a nightclub event, an outdoor rock concert and the Brit Awards ceremony.

The government said 58,000 people attended indoor and outdoor events in the Events Research Program in April and May, and there were "no substantial outbreaks" as a result.

But scientists cautioned that the results did not provide "direct evidence of the risk of coronavirus transmission at specific types of events." That's because only 15 per centof attendees reported the results of coronavirus tests taken both before and after the event, as they were meant to, and because infection rates in the U.K. were low at the time of the events.

To learn more, further pilot events are being held with bigger crowds including, contentiously, the Euro 2000 final at Wembley Arena next month that's set to be attended by more than 60,000 soccer fans.
