The World Health Organization says the highly contagious Delta variant has now been identified in 124 countries, and is expected to become the dominant strain within months.
This is 13 more countries than the previous week.
The WHO also said the global number of COVID-19 cases jumped 12 percent on-week, with over 190 million accumulated cases so far.
The U.S. is one country experiencing the rampant spread of the Delta strain, with COVID-19 cases nearly tripling over the past two weeks.
The country is also reporting more COVID-19 infections among children, who are not yet eligible to be vaccinated.
The American Academy of Pediatrics says over 23-thousand child COVID-19 patients were reported between July 8th and 15th, nearly two-fold the number seen in late June.
Amid the continued spread of the Delta variant, American health experts are stressing the importance of getting vaccinated.
"Our vaccines that we're using in this country are very effective against this variant, particularly, I point out, to the situation regarding advanced disease leading to hospitalizations and deaths where it's still well in the 90% of effectiveness."
As new cases surge in Britain, its Prime Minister, Treasury chief and the leader of the main opposition Labor Party are under self-quarantine after being exposed to COVID-19.
Germany is also grappling with the Delta variant, with its health minister warning the public that if case numbers keep rising at the current pace, the country could see the number of infections per 100-thousand people over the course of a week to exceed 4-hundred in September.
Over 50 million people, or 60 percent of Germany's total population have received at least one COVID-19 shot.
About 47 percent are fully vaccinated.
