WHITE HOUSE – All Americans should wear nonmedical masks to help prevent the spread of COVID-19, the U.S. government is recommending.

The new guidelines, from the U.S. Centers for Disease Control and Prevention amid the coronavirus pandemic, were announced Friday by President Donald Trump.

Trump stressed the recommendation was voluntary and said he would not be following it.

“You can do it. You don’t have to do it. I’m choosing not to do it,” he told reporters.

“Somehow, sitting in the Oval Office behind that beautiful Resolute Desk, wearing a face mask as I greet presidents, prime ministers, dictators, kings, queens — I just don’t see it,” Trump elaborated.

Some lack symptoms

The U.S. surgeon general, Dr. Jerome Adams, said donning the masks was, however, a good idea to try to prevent the virus from spreading, since many infected with it do not show any symptoms.

“We now know from recent studies that a significant portion of individuals with coronavirus lack symptoms,” he said. “This means that the virus can spread between people interacting in close proximity — for example, coughing, speaking or sneezing.”

The president and other officials stressed that people should not use the medical-grade masks, which are in short supply and needed by first responders and health professionals.

“The CDC is recommending that Americans wear a basic cloth or fabric mask that can be either purchased online or simply made at home,” Trump said.

He also announced that he was invoking the Defense Production Act to halt the export of “scarce health and medical supplies by unscrupulous actors and profiteers.”

“We need these items immediately for domestic use,” Trump said. “We have to have them.”

Canada, meanwhile, warned the Trump administration about halting the supply of masks to its neighbor and ally.

“The level of integration between our economies goes both ways across the border,” Canadian Prime Minister Justin Trudeau said Friday. “It would be a mistake to create blockages or reduce the amount of back-and-forth trade of essential goods and services, including medical goods, across our border. That is the point we’re making to the American administration right now.”

Canada will “pull out all the stops” to prevent the United States from blocking the exports of some medical equipment, Deputy Prime Minister Chrystia Freeland said.

Warning from 3M

A major manufacturer of the N95 respirators was also upset about the Trump administration’s action.

There are “significant humanitarian implications of ceasing respirator supplies to health care workers in Canada and Latin America, where we are a critical supplier of respirators,” 3M, a Minnesota-based multinational conglomerate, said in a statement Friday. “In addition, ceasing all export of respirators produced in the United States would likely cause other countries to retaliate and do the same, as some have already done. If that were to occur, the net number of respirators being made available to the United States would actually decrease.”

“I don’t blame ‘em — they can push back if they want,” Trump said when asked by VOA about the company’s comment. “We’re not happy with 3M.”
