The World Health Organization says the number of new COVID cases jumped 12% across the globe last week as the highly contagious Delta variant continues to spread. Indonesia recorded 350,000 new cases over the past week — a 44% increase and the highest total in the world. England, which just lifted all COVID restrictions, reported almost 300,000 cases. Earlier today Thailand and South Korea both set new daily records for COVID infections. The WHO says the Delta variant is now in 124 countries and will soon become the dominant coronavirus strain worldwide. This comes as China has rejected calls by the WHO to open a new investigation into the origins of the pandemic. An earlier probe found it was “extremely unlikely” that the coronavirus escaped from a lab in Wuhan where the first cases were detected. But many public health experts say key questions remain unanswered over the virus’s origins. Meanwhile, the United States has announced its borders with Mexico and Canada will remain closed until at least August 21. Canada recently announced vaccinated Americans will be allowed to enter the country beginning August 9.
