The US’s daily coronavirus cases have declined 65% in the last month — a record drop in the course of the nation’s outbreak. New cases reached an all-time high of 312,000 on January 8. Since then, they’ve fallen to a weekly average of around 73,000 per day.
Dr. Martin Makary, a professor of surgery at the Johns Hopkins School of Medicine, suggested in The Wall Street Journal that the most likely explanation for the decline is that the US could be close to reaching herd immunity.
In a Thursday op-ed, Makary predicted that COVID-19 would be “mostly gone” by April.
He wrote that infections have likely been far more widespread than data suggests — so much so, in fact, that the US will soon hit a threshold beyond which the virus won’t be able to pass easily from person to person.
