Nearly 100 world leaders and several dozen ministers are slated to speak at the U.N. General Assembly’s special session starting Thursday on the response to COVID-19 and the best path to recovery from the pandemic which has claimed 1.5 million lives, shattered economies in countries rich and poor.

Assembly President Volkan Bozkir says when he took the reins of the assembly in September it would have been better to hold the high-level meeting in June. Nonetheless, he said Wednesday that the session “provides a historic moment for us to come together to beat COVID-19.”

Here in the U.S., the head of the Centers for Disease Control and Prevention predicts the country is about to go through “the most difficult time in the public health history of the nation.”

Dr. Robert Redfield made the comment during a U.S. Chamber of Commerce Foundation webcast Wednesday.

Redfield says earlier surges in COVID-19 illnesses were concentrated in one area of the country or another, and health care workers and equipment could be shifted from one place to another to deal with it. But now, he says,all parts of the country are seeing rising infections and illnesses.

In Redfield’s words: “The reality is December and January and February are going to be rough times. I actually believe they are going to be the most difficult time in the public health history of this nation.”people.
