Since Wednesday afternoon, most of 203,000 people in the united States have been infected and at least 4.473 have died.
Now, most data show that people without symptoms are driving the spread, which has made senior officials reconsider whether the general public should wear masks.
New data from Iceland show that 50% of the people who were positive said that they were asymptomatic.
In United Statesit is estimated that 25% of the carriers of the coronavirus do not have symptoms, according to the director of the Centers for disease Control and Prevention (CDC, for its acronym in English).
“The information that we have confirmed now is that a significant number of infected people in reality remain asymptomatic. That can be up to 25%,” said the Director of the CDC, Dr. Robert Redfield, the NPR.
To prevent further spread, the foremost expert on infectious diseases says US health officials are rethinking the guidance on face masks.
Dr. Anthony Fauci said that “we bow down” to recommend that the general public use facial masks “if we don’t have the problem of removing the masks to health care workers who need it most.”
“We’re still not there, but I think that we are close to coming to a certain determination,” said Fauci.
If the federal officials to recommend widespread use of face masks, it would be a radical change in respect of the recommendations of the World Health Organization and the CDCwho said that face masks should only be used by health workers, those who are sick and those who are caring for someone ill.
“There is No specific evidence to suggest that the use of masks by the bulk of the population have some potential benefit,” said Monday the Dr. Mike Ryan, executive director of the program of emergencies of the WHO.
“In fact, there is some evidence that suggests otherwise in the misuse in the wearing a mask correctly or adjust them in right way”.
3 tips for using a mask
But this week, in the wake of new information on the spread asymptomatic of the virus, the guideline public could change, according to Adams. Then offered several tips on how to use the masks properly.
“If you’re going to use a cover for the face, try not to touch your face. Be careful of make sure you don’t touch your face,” Adams said on the “Today” show on NBC on Wednesday.
Adams has said that the people often touch the face to adjust the masks, which increases the risk of infection.
“No. 2: If you are going to use a cover for the face, keep the N95 masks for health care workers who need them,” noted Adams. N95 respirators must be properly adjusted to ensure that there is an open space and the people without medical training could use them incorrectly.
“No. 3: Use a cover for the face doesn’t mean you don’t have to practice social distancing,” he said.
“The most important thing that you can do at this time is to stay at home. We don’t want people to feel like ‘OK, I’m covering the face, so now it is okay to quit’”.
An important argument against the widespread use of masks is that the health workers do not have enough.
“We have a global shortage massive,” Ryan said. “At this time, the people most at risk of contracting this virus are the health workers first-line that are exposed to the virus every second of every day. The idea that they don’t have masks it’s horrible”.
So, some people are making their own masks. JOANN Fabrics and Craft Stores launched a video tutorial on how to make facial masks.
The top of the pandemic coronavirus is yet to come
White House officials they forecast that more than 100,000 people could be killed by coronavirusand that if the public practice of the perfection patterns of social distancing.
In mid-April, when it is projected that the virus will hit the country with more strength, up to 2,000 americans could die each dayas shown in a model cited by the White House.
Health officials indicate that the measures are working to slow the spread of the virus are the only hope for keep the number of dead in thousands and not in millions.
If the americans do not follow the patterns of social distancing, in the worst cases, may die up to 2.2 million people, said Dr. Deborah Birx, coordinator of response to the coronavirus in the White House.
More than two dozen states have issued orders to stay at home, and the federal government extended the patterns of social distancing until the 30th of April.
Birx ensures that there is an easy way to solve the pandemic of coronavirus. Up to the public to help stop the spread.
“There is not a magic bullet,” he said. “There is No vaccine or therapy is not magic. They are only behaviors. Each one of our behaviors translates into something that changes the course of this viral pandemic in the next 30 days.”
The evidence shows that social distancing helps
About 80% of the U.S. population now has orders to stay home, according to a count by CNN based on several orders state, county and city.
But on Wednesday, the vice-chairman Mike Pence said that it did not believe that it is necessary to a national order.
“It has been inspiring that in the last 15 days, the people in the states that have low penetration of the coronavirus outbreak still put into practice the guidelines for the entire nation,” he said.
The health officials point out that the efforts of social distancing seem to be bearing fruit, even in the King county of Washington state, the first epicenter of coronavirus in the country.
“We are seeing reductions in the person to person contact, which has improved progressively and has led us to a point where we are having a very positive impact,” said Dr. Jeff Duchin, public health officer for Seattle and King County.
In New York, an analysis by CNN shows that the average daily increase of cases in the last week was 17%, an important decrease in comparison with the 58% for the previous period of seven days.
A large-scale study found that early interventions, such as social distancing and the severe restrictions on the movement of people, have saved tens of thousands of lives in all Europe.
Scientists from Imperial College London studied interventions in 11 european countries and concluded that “together they had a substantial impact on the transmission.”
The researchers estimate that as of march 31, “interventions in the 11 countries avoided to 59,000 deaths”.
