CHICAGO, Ill. – A study published this month suggests that by lessening the amount of virus you take in by putting on a mask, you may also lessen the likelihood of getting severely sick if you contract COVID-19.As the race to a safe and effective coronavirus vaccine heats up, new research about masks is changing the narrative on their importance.Last week, CDC Director Dr. Robert Redfield called face masks the most “powerful public health tool we have.”“I might even go so far as to say that this face mask is more guaranteed to protect me against COVID than when I take a COVID vaccine,” said Dr. Redfield.It was a stark change from CDC messaging early on in the pandemic that face coverings would most likely only protect those around you.“That was because there was a lot of data at that time that you can shed the virus at high rates from your nose and mouth even when you feel well,” said Dr. Monica Gandhi, an infectious disease doctor and professor of medicine at the University of California – San Francisco.She co-authored newly published research in the New England Journal of Medicine that theorizes that not only do masks protect the wearer but they may even reduce the severity of the coronavirus when someone gets infected.“We realized that we should be messaging more strongly masks protect you as the wearer and protects others,” said Dr. Gandhi.It theoretically works much like the early days of vaccines that used small amounts of viruses to illicit an immune response in the body. So, by wearing a mask, you are only exposed to lesser amounts of the virus, if any, potentially building up a sort of immunity.“The more virus you get inside, the sicker you are, the less virus you have, the less sick you are. This is called a dose response and it's true of many infections,” said Dr. Emily Landon, an epidemiologist and infectious disease specialist at University of Chicago Medicine.Gandhi says the theory has already been studied and proven in animals.“There was a hamster study that looked at the COVID-19 virus and the more that the hamsters were given, the more sick they got,” she said.Dr. Gandhi says it could also explain the why according to the CDC, 40% of coronavirus patients are asymptomatic.“Countries that mask well have lower rates of severe illness than countries that don't mask well. So, putting it all together, this is our hypothesis.”And while the research is still theoretical, if it bears out, experts say universal mask-wearing could drive up the proportion of people who get less sick from the virus if they do contract it. 2579

CARLSBAD, Calif. (KGTV) – It opened with much fanfare back in September, but after a two week period of cancellations February, Carlsbad-based airline, Cal Jet was still dealing with setbacks in early March.“I can’t say that it didn’t [suffer],” said Cal Jet’s President, George Wozniak of their reputation.On Friday, he stood on the tarmac at McClellan-Palomar Airport, personally apologizing to travelers boarding a plane at 4:15 p.m. that had been originally scheduled to leave at 9 a.m.Wozniak said the passengers had been notified of the delay earlier in the day. The plane had experienced mechanical problems the night before and had to fly to Arizona last night for repairs.The delays come after the airline canceled nearly two weeks of flights, beginning just before President’s Day weekend.Wozniak said the plane they use, which is owned by Elite Air, had also been booked by NCAA basketball teams. “It was either a crew or aircraft scheduling problem, where if they had one pilot get ill and not show up, it could throw the whole thing off,” described Wozniak.They could theoretically still use it, but rather than risk more abrupt cancellations, he decided to clear the schedule until they could get the plane back full time.“It was not an easy decision to make,” said Wozniak.Cal Jet’s Yelp page says why. After the cancellations, the page was flooded with one-star reviews. “If I could give zero stars... or even a negative star review, I would confidently put this airline in that category,” wrote Rachel L.Another reviewer, Justin K. said his return flight was canceled last minute, forcing him and his pregnant wife to find last-minute accommodations back to Carlsbad.We finally decided to rent a car and drive 5+ hours with traffic, with my pregnant wife, stopping every couple hours for her to walk around for medical reasons, making the drive even longer.Wozniak said all the customers received refunds and a 0 flight voucher.He said they plan on expanding their coverage to several other cities later this year, which will include new planes as well.“We feel very confident going forward we’ll have the extra crew and airplanes necessary to fulfill that travel mission for these people without any real problems.” 2254

  

Capping days of commemorations of her extraordinary life, Supreme Court Justice Ruth Bader Ginsburg becomes the first woman in American history to lie in state in the U.S. Capitol.Ginsburg, who died last week at age 87, also will be the first Jewish-American to lie in state and just the second Supreme Court justice. The first, Chief Justice William Howard Taft, also had been president.Ginsburg’s casket will be brought to the Capitol Friday morning for a private ceremony in Statuary Hall attended by her family and lawmakers, and with musical selections from one of Ginsburg’s favorite opera singers, mezzo-soprano Denyce Graves. Democratic presidential nominee Joe Biden and his wife, Jill, planned to attend.Members of the House and Senate who are not invited to the ceremony because of space limitations imposed by the coronavirus pandemic will be able to pay their respects before a motorcade carrying Ginsburg’s casket departs the Capitol early afternoon.The honor of lying in state has been accorded fewer than three dozen times, mostly to presidents, vice presidents and members of Congress. Rep. John Lewis, the civil rights icon, was the last person to lie in state following his death in July. Henry Clay, the Kentucky lawmaker who served as Speaker of the House and also was a senator, was the first in 1852. Rosa Parks — a private citizen, not a government official — is the only woman who has lain in honor at the Capitol.Ginsburg has lain in repose for two days at the Supreme Court, where thousands of people paid their respects, including President Donald Trump and first lady Melania Trump on Thursday. Spectators booed and chanted “vote him out” as the president, who wore a mask, stood silently near Ginsburg’s casket at the top of the court’s front steps.Trump plans to announce his nomination Saturday of a woman to take Ginsburg’s place on the high court, where she served for 27 years and was the leader of the liberal justices.Ginsburg, the second woman to serve on the Supreme Court, will be buried next week in Arlington National Cemetery beside her husband, Martin, who died in 2010. 2122
