The United States continues to be the largest epidemic region in the world, with more than 160,000 cases, of which more than 3,000 have died.

According to statistics from Johns Hopskin University, the US recorded 19,988 new infections and 565 deaths, bringing the number of infections and deaths to 163,479 and 3,148, while 5,506 people have recovered. The death rate in America is about 1.9%, lower than the global average of 4.8%.

New York reported 66,497 cases, of which 1,218 died, the most heavily affected state due to Covid-19 in the United States. The New York City government filed an application to the federal government to set up the second field morgue. The morgue will be located in Queens, but the exact location is unknown.

"People should stay home. We want the governors to decide what they want to do in their state," US President Donald Trump said at a White House press conference on March 30.

Trump last week said he might reopen the country in mid-April because the shutdown poses economic risks, but appears to have changed his mind. He called on people to obey the 70-day restriction rules.

The US President believes that the next 30 days are important to prevent Covid-19 from continuing an outbreak. "Each of us contributes to the victory in this fight. Every citizen, family and business can make a difference in stopping the virus," Trump said. "This is our mutual patriotism. The challenge is ahead of the next 30 days."

In Seattle, Washington, a study found that community isolation and isolation has slowed the spread of the virus for the past three weeks. The number of people a patient can infect has nearly halved, from 2.7 in late February to 1.4 on March 18.

At least more than 256 million Americans, or 78% of the population, are under blockade, while 4.5 million can apply for unemployment benefits, the highest in history. About one million Americans have been tested for nCoV, but so far only about one-third have received the results.

Many hospitals in the United States are lacking of medical protective equipment, posing a risk of virus infection during treatment of Covid-19 patients. Experts warn New York will suffer a more serious outbreak than Wuhan, China or Italy's Lombardy region if the current rate of new nCoV infections continues.

The US Food and Drug Administration (FDA) has approved a self-sampling procedure for suspected nCoV infections and will begin this week. This procedure will speed up testing, eliminate unnecessary protective dressing and help people feel more comfortable.

Covid-19 appeared in 200 countries and territories after its inauguration in Wuhan, China in December 2019. The epidemic has infected more than 784,000 people and nearly 38,000 died worldwide. The epidemic situation in China seems to be under control, but complicated in the US and European countries.
