In a blink of an eye, it has been nearly 4 months since the outbreak of the new crown epidemic in the United States. Wind data shows that as of July 11, local time, the cumulative number of confirmed cases of new coronary pneumonia in the United States exceeded 3.35 million, with a total of 137,000 deaths, and more than 63,000 new cases in a single day. These three data ranked first in the world. Zhang Wenhong, director of the Department of Infectious Diseases at Huashan Hospital affiliated to Fudan University, made it clear in an interview with the media recently that the first wave of the epidemic in the United States has not yet ended.

US President Trump wore a mask when visiting wounded soldiers and front-line medical staff at a military medical institution in Maryland. US media reported that Trump has worn a mask publicly for the first time since the outbreak of the new crown pneumonia in the United States. Even if Trump puts on a mask, there will be criticism and sarcasm.

Some netizens said in the comments: "My God! This is simply big news!"

Some netizens said: "Should we applaud and cheer? It took 5 months to put on the masks."

Some netizens sarcastically said: "He looks much better now, so he should cover his entire face."

Nowadays, more and more public health experts in the United States are urging people to wear masks, and some states have successively introduced “mask injunctions” on their own, but there are many people who do not take it seriously or even fiercely oppose it. As a result, whether Trump wears a mask or not has become a focus of the American media. What are Americans still struggling with about masks?

Before the trip, Trump told the media at the White House: "I have never opposed wearing a mask, but I believe that wearing a mask requires time and place."

Since the new crown epidemic broke out in the United States in March this year, Trump has refused to wear a mask in public. According to U.S. media reports, when Trump visited a Ford automobile factory in Michigan in late May, although the company reminded the White House in advance that the factory has regulations for wearing masks, Trump only wore masks at the beginning of the inspection. And do not allow reporters to shoot. He said: "I don't want the media to see it."

Since late June, as the epidemic in the United States has become more serious, many politicians from the Democratic and Republican parties have urged Trump to lead by example and show the American people the importance of wearing masks to prevent the spread of the new crown virus. Many public health experts in the United States have also repeatedly stated that wearing masks is the key to preventing the spread of the new crown virus.

However, the White House refused to force people across the United States to wear masks in public places during the epidemic. More than 20 states in the United States have required people to wear masks in public places, but the severely affected states such as Arizona and Florida have yet to issue such governor orders.

Not wearing a mask is not a sign of strength, nor is it a sign of political stance. "New Jersey Governor Philip Murphy said. "Not wearing a mask is selfish. It's as simple as that. It means that you feel good about yourself, but you are actually harming others." "
