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 The study claims there may be a “protective effect” for blood group O. However this study has not been peer-reviewed yet and the exact kind or extent of “protective effect” is not known.In early June, the site 23andme.com released results from information gathered from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 swimmer died following an apparent shark attack near Bailey Island, Maine, on Monday, the Maine Department of Natural Resources confirmed.The agency said that kayakers brought the unidentified woman to shore after swimmers saw she was injured from an apparent shark attack. She was pronounced dead at the scene by EMS responders.Swimmers and boaters in the area were being told to remain cautious following the attack.The University of Florida, which has a database of shark attacks in the United States, has not reported any such attacks from 2010 through 2019 off the coast of Maine. On average, there are 45 shark attacks in the United States a year. But fatal shark attacks are very rare in the US – just seven reported fatalities in the last decade, and three in the last four years.According to the University of Florida, there was a fatal shark attack off the coast of California in May, marking the first US shark attack death in nearly two years. 965

A nor'easter that left at least one person dead in the Northeast has mostly passed but hundreds of thousands of homes remain without electricity Friday.More than 530,000 customers are without power along the East Coast from Virginia to Maine after the region's second major storm in a week whipped the area with heavy snow and stiff winds, downing power lines and leaving precarious road conditions.Boston recorded six inches of snow on Thursday while parts of northwestern Massachusetts saw up to 24 inches, the National Weather Service said.A few lingering bands of snow and snow flurries are expected to move out of the region by Friday afternoon, CNN meteorologists said.  689

A new scientific model estimates 130,000 lives could be saved by next Spring if there is universal mask use in public. Without changes, the United States could be ontrack to record more than 500,000 deaths from COVID-19 by March 2021, the study reports.“We find that achieving universal mask use (95% mask use in public) could be sufficient to ameliorate the worst effects of epidemic resurgences in many states,” the study stated.The findings, published Friday in the journal Nature Medicine, found even if 85 percent mask use was achieved and current social distance policies remained in effect, it could result in an additional 95,000 lives being saved.According to the study, the national average for self-reported mask wearing is at just 49 percent as of late-September.The researchers ran scientific model projects using information from states about when they would implement stricter lockdown or stay-at-home orders to make their outcomes as realistic as possible based on current stated parameters and orders.These findings come as the U.S. struggles with a resurgence of COVID-19 cases.The country recorded more than 75,000 new infections Thursday alone, according to the New York Times.There are now a total of more than 8,450,000 positive COVID-19 cases since the pandemic started in the country, and at least 223,000 deaths from the disease. 1362
