A recent study appears to show a person’s blood type might indicate whether they will develop severe respiratory failure if they contract COVID-19.The study sequenced genomes of 1,600 COVID-19 patients in Spain and Italy who had been hospitalized with severe respiratory failure and compared the results to DNA sequences of 2,205 healthy subjects.Results appear to show that people with type A blood had a higher chance of developing severe respiratory failure as compared to people with O blood type. The study claims there may be a “protective effect” for blood group O. However this study has not been peer-reviewed yet and the exact kind or extent of “protective effect” is not known.In early June, the site 23andme.com released results from information gathered from 750,000 participants who identified they had COVID-19. The genealogy company said their research suggests a similar effect in people with O blood type. “Individuals with O blood type are between 9-18% percent less likely than individuals with other blood types to have tested positive for COVID-19, according to the data,” a company statement said.They said while there was a significant difference in those with O blood type, there “appeared to be little differences in susceptibility among the other blood types.”However, some are questioning this idea that people with type O blood are protected. Laura Cooling is the director of immunohematology at the University of Michigan. She noted that the idea that having type O blood is protective doesn’t match with current COVID-19 infection rates.Type O blood is usually more prevalent among African Americans, according to the American Red Cross, yet new information from the CDC and states indicate African Americans have experienced disproportionately high COVID-19 infection rates. Cooling says there are many factors to consider.“It’s what your blood type is, relative to the other person who exposed you, relative to all the other genetic and acquired health conditions you have,” she told Chemical and Engineering News on the matter. 2069

A San Diego teenager will use her family's Spring Break trip to Washington, D.C., to advocate for stronger gun control laws.Faith Campbell, a Sophomore at Frances Parker School in Linda Vista, already has a meeting set up with Representative Susan Davis to discuss gun reform. She also has a stack of hand written letters from herself and her classmates to deliver to other area Congressmen and women."A letter is really powerful," Campbell says. "It shows that someone took the time out of their day to write specifically to this person."Campbell says she wrote a letter to Representative Davis after the shooting at Marjory Stoneman Douglas High School in February. Rep. Davis wrote back asking is she would like to meet.Campbell took part in last month's March for Our Lives in San Diego, joining thousands of others to call for stricter gun control laws. But she says she doesn't want the momentum to stall now that the protests and marches are over.Now, Campbell is inviting all of her classmates and fellow teens to write letters. She says she'll deliver them while she's in DC."It doesn't really matter how many letters I get," she says. "It's just the fact that people are writing."She says she'll take any letter written by a teen if they can get it to her by this Friday, April 13th. The letters can be dropped at her father Richard Campbell's office, Procopio Law Firm, at:525 B. Street, Suite 2200San Diego, CA 92101  1452

A potentially catastrophic Category 4 Hurricane Michael has made landfall as the strongest hurricane to hit the Florida Panhandle in recorded history, with its winds and storm surge wreaking havoc along the shore.Michael's extremely dangerous center crossed near Florida's Mexico Beach on Wednesday afternoon with sustained winds of 155 mph, the National Hurricane Center said.Photos: Hurricane Michael to slam US coastEarlier, Gov. Rick Scott called Michael "the worst storm that our Florida Panhandle has seen in a century."Streets were flooding in the Panhandle city of Apalachicola. In Panama City Beach, winds of about 100 mph furiously whipped the trees in the early afternoon as siding ripped from a building got caught against a fence.Earlier in that oceanside city, video from a meteorologist showed new construction collapsing in high winds.Among the concerns: Flash-flooding with heavy rain; life-threatening storm surges up to 14 feet high; and devastating winds, not just in the Panhandle, but southern Alabama and Georgia. 1044

A study that was pre-published on Wednesday indicates that a coronavirus mutation is causing the virus to be more contagious, a study authored by the Houston Methodist Hospital found. The study, however, concluded that the virus is not more potent.The study examined 5,000 COVID-19 strains from the Houston metro area. The study found very two distinct waves over the summer.The researchers found that COVID-19 infections from the second wave contained the Gly614 amino acid replacement in spike protein. The researchers said that while this amino acid caused “significantly higher virus loads,” this did not increase the potency of the virus.“We found little evidence of a significant relationship between virus genotypes and altered virulence, stressing the linkage between disease severity, underlying medical conditions, and host genetics,” the study said. “Some regions of the spike protein - the primary target of global vaccine efforts - are replete with amino acid replacements, perhaps indicating the action of selection," according to a summary of the findings.The researchers said that the study is intended to help scientists understand the composition and trajectory of future infection waves.It is important to note that the study has not been peer reviewed, and was limited to cases in the Houston area. 1326
