U.S. Coronavirus Hotspot Updates: The Latest on COVID-19 Cases in New York, Detroit, New Orleans

Three of the five states with the most coronavirus cases are approaching the peaks of their outbreaks and the White House Coronavirus Task Force is expecting them to hit at the same time.

About 337,000 people in the United States have tested positive for the new coronavirus, more than double the number of cases in any other country. In Michigan, Louisiana and New York—three hot spots accounting for more than half the country's deaths—the peak in mortality is expected to hit simultaneously in the next five to six days.

Dr. Deborah Birx, a top advisor on the task force, didn't offer projections for the death toll during Saturday's briefing but referred people to the prediction on Healthdata.org. By August, the website projected 746 people in Louisiana would die, 2,963 in Michigan and 15,618 in New York.

Louisiana has already had 477 deaths, Michigan, 617, and New York has reported 4,159, as of Sunday.

"If mitigation in New York worked—and we believe it is working—the cases are going to start to go down, but the mortality will be a lag behind that because of the comorbidities and other conditions," Birx said.

New York is by far the largest outbreak in the U.S. and has had 122,031 cases, according to Governor Andrew Cuomo's Sunday briefing. The number of deaths over the past few days has been dropping for the first time, but the governor added it was too early to determine the significance of the data. It could be a "blip" or it could be the "hopefully beginning of a shift in the data."

At least 12,000 New Yorkers have been discharged from the hospital, including 1,700 in one day. This is "great news," according to Cuomo, but it was prudent lockdown measures, including closing non-essential businesses and limited restaurants to takeout and delivery service remain in place.

"As we've said before, the coronavirus is truly vicious and effective at what the virus does. It's an effective killer," Cuomo said on Sunday. "People who are very vulnerable must stay isolated and protected."

Michigan, the state with the third-highest case count, has similar measures in place to slow the spread of the virus. They're expected to expire at midnight on April 13, but it's possible the executive order will be extended. President Donald Trump's social distancing guidelines will be implemented until April 30 and on Thursday, Governor Gretchen Whitmer said the stay-at-home order will continue as long as science identifies it as the "most important" mitigation measure.

Of the 15,718 cases in the state, 7,518 are in Wayne County, where Detroit is located, according to the state health department. The neighboring countries of Macomb and Oakland have 2003 and 3035 cases, respectively.

Louisiana, the state with the fifth-biggest outbreak, has had fewer cases than Michigan and as of Sunday, the state health department reported 13,010 cases. Governor Jon Bel Edwards claimed on March 22 that the state had the fastest growth rate of confirmed cases and that there was reason to believe they'd be the next Italy.

All but three parishes in Louisiana have reported cases and Orleans Parish, where New Orleans is located, has been hit hardest. More than 4,000 people in the parish tested positive and an additional 3,088 cases were reported in the neighboring parish of Jefferson.

"One of the biggest surprises is Louisiana because it started off so good, and then all of a sudden, it shot up like a rocket," Trump said on Saturday. "But we are going to try and have ventilators wherever we possibly can."

The federal government is sending supplies across the country, focusing on the areas that have been hit hardest, according to Trump. In some cases, that means explaining to state officials that they won't receive the supplies they requested because their present circumstances don't require it.

Given projections about when cases and deaths are expected to peak, Trump said between this week and next it will probably be the "toughest week." But, mitigation measures appear to be working in some areas and the president called it the "patriotic duty of every citizen" to do their part to slow the spread of the virus by staying home and engaging in social distancing.
