To wear a mask, or not to wear a mask ... Here's a timeline of what officials have said:
There’s a mandatory push for Americans to wear masks, but do they actually work? And are the government’s ever-changing policies on face masks reliable or helpful?
On April 3, the Trump administration and the Centers for Disease Control and Prevention also reversed their policies on face mask, and said all Americans should wear cloth face coverings and not — as it previously said — just medical workers. President Trump cited “recent studies” of asymptomatic transmission for the U-turn, while the CDC cited “new evidence.”
Dispatches from a pandemic:‘When I hear an ambulance, I wonder if there’s a coronavirus patient inside. Are there more 911 calls, or do I notice every distant siren?’ The public was, understandably, confused. N95 masks appear to be effective for health-care workers. This study says N95 medical-grade masks do help filter viruses that are larger than 0.1 micrometers The coronavirus is 0.125 um. They have “efficacy at filtering smaller particles and are designed to fit tightly to the face,” it said.
They say the best way of staying safe is to avoid public settings with other people whenever possible. “People may also wear masks inappropriately, or touch a contaminated part of the mask when removing it and transfer the virus to their hand, then their eyes and thus to the nose,” they wrote in The Conversation. “Masks may also provide a false sense of security, meaning wearers might do riskier things such as going into crowded spaces and places.
Feb 29: Surgeon General tweets: “Seriously people: STOP BUYING MASKS! They are NOT effective in preventing general public from catching #coronavirus, but if health-care providers can’t get them to care for sick patients, it puts them and our communities at risk!” April 3: President Trump says his administration recommends wearing cloth face coverings in public settings, but the president says he won’t wear a mask himself. “From recent studies, we know that the transmission from individuals without symptoms is playing a more significant role in the spread of the virus than previously understood,” Trump said. However, he remained circumspect on the usefulness of masks. “You don’t have to do it.
