Signs of encouragement as US sees drop in Covid cases and hospitalizations

CDC data shows 29% decrease in cases over two weeks in September but experts say virus remains a significant threat

The United States has seen a dramatic drop in the number of Covid-19 cases and hospitalizations in recent weeks, a trend that epidemiologists see as an encouraging sign that the Delta wave of the virus has peaked nationally.

The seven-day average of daily new cases in America dropped from about 151,000 on 14 September to about 106,000 on 29 September, a 29% decrease, according to data from the Centers for Disease Control and Prevention.
