At a press briefing on June 8, Tedros Adhanom Ghebreyesus noted that about 75% of cases reported to the U.N. health agency on June 7 came from 10 countries in the Americas and South Asia. He noted that more than 100,000 cases have been reported on nine of the past 10 days and that the 136,000 cases reported June 7 was the biggest number so far.

Tedros said most countries in Africa are still seeing an increase in cases, including in new geographic areas even though most countries on the continent have fewer than 1,000 cases. At the same time, we're encouraged that several countries around the world are seeing positive signs, Tedros said. In these countries, the biggest threat now is complacency.
