More studies seem to indicate there is some connection between a person’s severity of COVID-19 symptoms and their blood type. However, experts agree more research is needed and these studies do not allow people with certain blood types to disregard pandemic safety precautions.The two latest studies, one from Denmark and one from Canada, both appear to show that people with blood type O may be slightly less vulnerable to COVID-19 and have a reduced chance of getting severely ill.In the Danish study, researchers looked at more than 7,400 people who tested positive for COVID-19. Of those, 38.4 percent had blood type O, while other research indicates that blood type makes up about 41.7 percent of the population.In the Canadian study, they looked at the length of hospital stays for 95 people critically ill with the coronavirus. They found the portion of patients who needed mechanical ventilation was higher in those with blood type A or AB when compared with a group of patients with blood type O or B.Researchers also found the blood type A or AB group had longer stays in the intensive care unit, a median of 13.5 days, compared to the other group with blood type O or B who had a median of 9 days."I don't think this supersedes other risk factors of severity like age and co-morbities and so forth,” Dr. Mypinder Sekhon, who is a clinical assistant professor in the Division of Critical Care Medicine and Department of Medicine at the University of British Columbia told CNN."If one is blood group A, you don't need to start panicking. And if you're blood group O, you're not free to go to the pubs and bars."Researchers say this information could be used in some way in regard to treatment of COVID-19. Both studies were published in the journal Blood Advances this week.Previous studies have indicated similar results in patients with blood type O.In July, a study looking at 1,600 patients in Spain and Italy showed slightly higher rates of severe respiratory failure in patients with blood type A compared to those with blood type O.Also this summer, the genealogy website 23andMe.com released data they collected from 750,000 participants who identified they have tested positive for COVID-19.“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 at the time. 2425

More than 600,000 people signed up for Obamacare in the first four days of open enrollment, far outpacing last year's rate.Nearly a quarter were enrolling for the first time, while the rest renewed coverage, according to statistics released Thursday by the Trump administration. The period covers Nov. 1 through Nov. 4.The data provides the first look at how Obamacare will fare under an administration determined to dismantle the health reform law. While Trump officials are maintaining the federal exchange, healthcare.gov, they have slashed open enrollment advertising and support. Also, consumers will have only six weeks to sign up for coverage on the federal exchange, rather than the three months or more they had in previous years. Obamacare supporters were quick to jump on the data, noting that the average daily pace was nearly double that of last year's.Related: 5 changes for Obamacare open enrollment for 2018"This is a great start to open enrollment and is further evidence that people want health insurance and that they're finding coverage they can afford," said Lori Lodes, a former Obama official and co-founder of Get America Covered, which is aiming to boost sign ups.Are you shopping for Obamacare coverage for 2018?

More than 1.4 million children under the age of 19 have tested positive for COVID-19 in the U.S. since the pandemic started earlier this year, according to the American Academy of Pediatrics and the Children’s Hospital Association.New data released this week shows that as of December 3, 1,460,905 children have tested positive in this country, representing more than 12% of total reported cases at that time.In August, children under 19 made up 9% of all COVID-19 cases in the U.S.During the last two weeks of November, there was a 23% increase in the number of children who tested positive for the coronavirus, going from a total of 1.183 million in mid-November to 1.460 on December 3.Children still make up a small number of the country’s hospitalizations and deaths from COVID-19; ranging from 1-3% of hospitalizations depending on the state, and 0-.23% of all COVID-19 deaths.Last week, the AAP released guidance on returning to youth sports during the pandemic. They encourage children to wear cloth face coverings at all times “for group training, competition, and on the sidelines.” 1099
