ATLANTA, Ga. – The head of the Centers for Disease Control and Prevention says the United States could get the coronavirus pandemic under control in one to two months if all Americans wear face coverings in public spaces.CDC Director Dr. Robert Redfield made the statement during an interview with the Journal of the American Medical Association, or JAMA, on Tuesday.“I think the data is clearly there that masking works,” Redfield told JAMA. “I think that if we can get everybody to wear a mask right now, I really do think that over the next four, six, eight weeks, we can bring this epidemic under control.”Redfield’s comments coincided with the release of two case studies that show how wearing face coverings can significantly reduce the transmission of the coronavirus.One of the studies, from JAMA, showed that a Boston hospital system reversed the infection trajectory among its employees and patients by adhering to universal masking policies.In the second study, the CDC highlighted how wearing a mask prevented the spread of infection from two hair stylists to their customers in Missouri.“Among 139 clients exposed to two symptomatic hair stylists with confirmed COVID-19 while both the stylists and the clients wore face masks, no symptomatic secondary cases were reported; among 67 clients tested for SARS-CoV-2, all test results were negative,” wrote the CDC. “Adherence to the community’s and company’s face-covering policy likely mitigated spread of SARS-CoV-2.”Experts say the virus that causes COVID-19 is thought to mainly spread from person to person, mainly through respiratory droplets produced when an infected person coughs, sneezes or talks.“These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs,” writes the CDC. “Spread is more likely when people are in close contact with one another (within about 6 feet).”In an editorial published by JAMA, the CDC affirmed that cloth face coverings are a critical tool to help stop this kind of spread.“We are not defenseless against COVID-19,” said Redfield. “Cloth face coverings are one of the most powerful weapons we have to slow and stop the spread of the virus – particularly when used universally within a community setting. All Americans have a responsibility to protect themselves, their families, and their communities.”The U.S. continues to lead the world in the number of COVID-19 cases, with nearly 3.5 million infections reported as of Thursday morning, according to a tally by Johns Hopkins University.Click here to learn more about COVID-19 from the CDC. 2600

As states across the country grapple with an increase in coronavirus cases and a huge demand for tests, many businesses are looking for other ways to get more mileage out of their supply chain.Like with anything else, supply and demand is a constant struggle. In this unprecedented era, the demand for things like coronavirus tests is so large that public health departments don't have a choice but to figure out ways to make our supplies last. Several states are examining pooled testing. California's Public Health Department says it's to "better leverage testing resources."Pooling is something that blood banks have used for decades to keep their blood supply safe. Dr. Claudia Cohn is the Chief Medical Officer of the AABB, formerly known as the American Association of Blood Banks.“If you have 100 people that need to be tested and if you test each of them, you’ll do 100 tests. If you find that your test is sensitive enough that you can pool together 20 samples at the same time, instead of having 100 tests, you can have five pools of 20,” Dr. Cohn said.Now, if one of those five pools is positive, then Dr. Cohn says, "You’ll need to break it out and test each of those separately. So, let’s say you have one positive person in a pool of 100 people, you either do 100 tests and find one positive or you do five pools of 20, four of those pools will be negative, so you’ve done 4 pools and covered 80 people."The test works by taking a tiny sample from each person who was tested.“When you take a swab from everyone’s nose, you isolate the DNA from that swab,” Dr. Cohn said about the PCR test, which is generally a nose swab. “It’s not a lot, it’s a small amount but it’s enough. Because these tests are very, very sensitive.”Those tests are so sensitive, and they have to be, that pooling can really only work if the test can handle, as in detect, multiple samples at once. The FDA mandates that.“The FDA is quite demanding as they should be in terms of making sure tests work well and are safe,” Dr. Cohn said.And Dr. Cohn says, pooling wouldn't work in an area where there's a large outbreak, which means a large number of people would test positive regardless of pooling. In the blood world, this strategy has been perfected.“You are taking 100 samples and taking a drop from each sample and putting it together,” Dr. Cohn said. “You are testing every single person who comes through. In the blood world safety is before everything."Blood banks test for HIV, Hepatitis C and B and well as COVID-19 antibodies, according to the American Red Cross. And, as this pandemic moves through our communities, Dr. Cohn says our blood supply needs to remain strong.“After that initial spike, it went down again and that was okay because elective surgery had been canceled, so the demand for blood had gone down as well so for a while we were at a good balance of demand and supply. But then elective surgeries opened up and hospitals went back to full service and we’re in a shortage again,” Dr. Cohn said. 3017

At least seven people have been killed and six attackers "neutralized" Friday in Burkina Faso after attacks on the national army headquarters and the French Embassy, a government minister said.It's not yet clear who was behind the violence in the West African nation's capital, Ouagadougou.France's special envoy to Africa's Sahel region, Jean-Marc Chataigner, urged people to avoid the city center in a tweet referring to a "terrorist attack."Rémi Dandjinou, Burkina Faso's minister of communication, told CNN that an explosive device was used in the attack at the General Staff of the Armed Forces. At least five people were killed and two attackers "neutralized" there, he said.Four attackers were also "neutralized" and two Burkina Faso security members killed at the French Embassy, according to Dandjinou.He cautioned that the death toll might change.A spokesman for the French Ministry of Defense told CNN the situation at the embassy was under control.Freelance journalist Yacouba Ouédraogo, who is in Ouagadougou, told CNN the shooting had stopped and that the people who attacked the army headquarters wore Burkinabé army clothes.A government statement urged people to keep calm and avoid areas where there might be gunfire.The French Embassy earlier said on Facebook that attacks were underway there and at the French Institute, a cultural organization about a mile away.France's ambassador to Burkina Faso, Xavier Lapdecab, urged people via Twitter to act with "absolute precaution" as the attack was ongoing.Burkina Faso's national police warned people to move away from areas around the "vicinity of the Prime Ministry -- and the United Nations roundabout" in a post on its Facebook page. "The specialized units of the defense and security forces are in action," it said.The Prime Minister's office later posted on Facebook that it was not affected by the attack.The US Embassy urged people to seek shelter."Attacks are reported to be ongoing in downtown Ouagadougou, in the Koulouba area. The affected area includes the Chief of Staff Headquarters. Avoid downtown Ouagadougou. Shelter in place. Monitor local media for updates," it said on Twitter.France has a military presence in Burkina Faso as part of Operation Barkhane, which was launched in 2014 to combat jihadist activity across the Sahel region.The West, particularly France, considers Burkina Faso a key ally in the fight against al Qaeda in the region.The country was formerly known as the Republic of Upper Volta when it was established in 1958 as a self-governing colony under France. It gained full independence in 1960.It's not the first time that sites in the capital have come under attack.An attack by gunmen last year on a restaurant in Ouagadougou left at least 18 people dead, including two attackers. The victims were of several different nationalities.That assault echoed a similar one in 2016 on a cafe and hotel popular with Western diplomats in the same district of the city that left 29 dead. Responsibility for that attack was claimed by an al Qaeda affiliate, al Qaeda in the Islamic Maghreb.Later that year a jihadist assault on the Grand-Bassam beach resort killed 16 in neighboring Ivory Coast.  3206

At least five people have been killed in a ferocious storm that hammered the Northeast with powerful winds, relentless rain and historic flooding.The nor'easter moved out to sea Saturday, but not before it knocked out power -- perhaps for days -- to more than 900,000 customers from the mid-Atlantic to New England."People in these homes need to plan for a prolonged outage," Kurt Schwartz, director of the Massachusetts Emergency Management Agency, said Friday night. "This is a multi-day restoration event."RELATED:?'Bomb cyclone' pounds east coast with heavy flooding, high winds   The flooding is "the worst that we've seen in years," said Capt. John Dougan of the Quincy, Massachusetts Police Department, which had carried out more than 250 rescues between 8 a.m. Friday and midmorning Saturday. "We're seeing homes underwater, their basements were flooded out, the electricity was off."Emergency officials urged residents on higher ground to stay indoors, even after the storm pushed out."This is not a time to be out sightseeing and gawking, so please stay at home and stay out of our way," James Boudreau, the town administrator for Scituate, Massachusetts, said Saturday.Some 19 million people were still under a coastal flooding warning early Saturday afternoon.The storm morphed Friday into a "bomb cyclone" after undergoing a rapid pressure drop known as bombogenesis. It slammed much of the Northeast with heavy snow and rain, prompting significant coastal flooding and hurricane-force gusts in New England.Winds along parts of the Massachusetts coast that whipped in excess of 90 miles per hour are due to ease Saturday, CNN forecasters said.The storm also dumped heavy snow from Ohio to New England and into upstate New York, where more than 3 feet was recorded.Weak phone connection?

Aftermath response: The governors of Maryland and Virginia issued emergency declarations, allowing state and local agencies to help those affected.? Flight cancellations: About 250 flights in the storm zone were canceled Saturday, according to the flight-tracking website FlightAware.com. That compares with more than 3,000 US flights scratched Friday, most at the busiest Northeast airports in Boston, Philadelphia and New York.? Amtrak back in service: Amtrak resumed modified service at 6:20 a.m. ET Saturday, on its Northeast Corridor between Washington and New York, and planned to resume service between New York and Boston beginning at 8:40 a.m., the provider said.Five killed by falling treesAt least five people died in the storm, all killed by falling trees, authorities said. They include: a 77-year-old woman in Kingsville, Maryland; an 11-year-old boy in Putnam County, New York; a 44-year-old man in James City County, Virginia; a 6-year-old in Chesterfield County, Virginia; and a Newport, Rhode Island, man in his 70s.The 11-year-old was in his home when a large tree came crashing down, trapping him. A responding deputy tried to free the boy, whose mother was taken to hospital.Another young boy, just 6 years old, suffered a similar fate when a tree fell through his Virginia mobile home as he was sleeping on a top bunk bed. The boy was rushed to hospital, but his mother told the station his organs were failing."Doctors say we have to let him go," she told CNN affiliate WRIC. Cynthia Creighton's son was in her car when a neighbor's tree fell on top of the vehicle in Watertown, Massachusetts."The house shook, and we heard a noise. We didn't know what it was," Creighton told CNN affiliate WHDH. "We ran out, my son was still in the car with the tree on top of it."Creighton's son, who was in the back seat, was not injured, she said.Boston under waterHigh tides on Friday powered coastal flooding in Boston and other parts of Massachusetts, leaving streets awash for the second time since a massive nor'easter in early January.Kayakers paddled down Boston streets and National Guard members rescued 50 people from their homes in nearby Quincy, sometimes carrying them to safety in the scoopers of front-end loaders, CNN affiliate WBZ reported.Boston Harbor has only seen tides above 15 feet twice -- in 1978 and in January, during the last bomb cyclone. A high tide late Friday morning came up a little short, reaching 14.67 feet, but still sent water sloshing through the streets of East Boston.More record-setting high tides might strike Boston Harbor on Saturday during the midday high tide.With the moon full, the tide is at its highest point of the month, and the storm surge could drive as much as 4 feet of water into coastal neighborhoods, CNN meteorologists said. Massachusetts emergency officials said tides "will be astronomically high" in the next few days."I encourage all residents to be mindful of the storm and encourage employers to take the weather into consideration, which will mostly impact the coastal areas of our city," Boston Mayor Marty Walsh said.In Boston, many streets were closed and city officials advised people not to drive or walk in high water.Historic flooding prompts rescuesQuincy residents who were rescued from inundated homes told CNN they'd never seen anything like this weekend's flooding."It was pretty scary," said Alyssa Fitzgerald. "Once you saw the National Guard, that's when I was like, 'OK, we should have evacuated.'"Fitzgerald and her husband hunkered down overnight after their home lost power with their 3-year-old son and 1-year-old daughter, she said."Not like anything we've had before," Fitzgerald said. "Much worse than the snowstorm we had."Only a few storms even can compare with this level of flooding, including a 1978 blizzard, a storm in 1991 and January's bomb cyclone, Dougan, the Quincy police captain, said Saturday."We've been doing evacuations all through the night and today," he said.The-CNN-Wire? & ? 2018 Cable News Network, Inc., a Time Warner Company.

At X3 Sports, trainers have a goal of bringing out the warrior within their students by building up their cardiovascular endurance and their self-confidence.After being shut down because of COVID-19 concerns, this mixed martial arts gym in Atlanta is reopening and seeing a major increase in enrollment.“Since a lot of things have been going on in our community, it has increased at least 50% than what it was,” kickboxing coach Rica Grandison said.Grandison says more people are taking these self-defense classes and citing concerns ranging from the pandemic to the protests.She added that these students enrolling represent all races, genders and sexual orientations:“I am part of the LGBTQ community,” Grandison said.“I’ve been called the 'N' word just waiting for a bus. I’ve been called the 'D' word just hanging out with my partner, my significant other at the time,” she said. “So, I have been there.”Now the X3 coaches are sharing their championship credentials with gym members like Shannon Dunlap, who joined this gym to get stronger physically and emotionally.“I am a lot more comfortable in my body; I’m a lot more self-assured,” she said. “I don’t get nervous walking down the street.”The coaches at X3 say the more someone trains, the more muscle memory they will develop. Which means if they ever become a victim of an act of violence, it’s easier to escape that situation without things getting even more physical.“If somebody’s charging you just, just give them a push kick," Grandison said. “Push them away, knock them down, run away.”While Grandison says the best fight is a fight that never happens, she also believes it best for people to have the physical skills to defend themselves. 1714
