World Health Organization Director General Tedros Adhanom Ghebreyesus said Monday that global COVID-19 cases are plateauing but at an unacceptably high rate.

Globally, we are now seeing a plateauing in the number of COVID-19 cases and deaths, with declines in most regions including the Americas and Europe, the two worst-affected regions, Tedros said at a news briefing. But its an unacceptably high plateau, with more than 5.4 million reported cases and almost 90 thousand deaths last week.

After rising throughout March and April, cases worldwide have now peaked and come down slightly, according to figures from Our World in Data, but there are still about 780,000 new cases every day, and almost 13,000 deaths. 

Cases have started to level off in India, which is facing a severe crisis, but they are still at the very high level of almost 400,000 every day, according to Our World in Data. 

The United States, where there is now an abundant vaccine supply, has seen cases decline, though Tedros warned that poorer countries do not have the same access to vaccines. 

The shocking global disparity in access to vaccines remains one of the biggest risks to ending the pandemic, he said. 

High- and upper-middle income countries represent 53 percent of the worlds population, but have received 83 percent of the worlds vaccines, he added. By contrast, low- and lower-middle income countries account for 47 percent of the worlds population, but have received just 17 percent of the worlds vaccines.

The Biden administration has been facing calls to take greater action to help other countries. It has taken some steps, like announcing plans to donate 60 million doses of AstraZeneca vaccine over the next couple of months. It also backed a waiver for vaccine patents at the World Trade Organization, but that process could take months to play out. Some experts say a more useful route in the near-term would be focusing on increasing supplies of raw materials and boosting manufacturing capacity.
