A subject coughing in a cyclic incident. Top view of airborne droplet transmission with and without wearing a surgical mask. The top and bottom figures show the results at 4 s and 5 s, respectively. We consider a surgical mask that exhibits an initial efficiency of ～91%. The cover does not prevent the transport of the saliva droplets entirely away from the subject. Many droplets penetrate the mask shield and some saliva droplet disease-carrier particles can travel more than 1.2 m. For visualization, the droplets were scaled by a factor of 600 compared to their actual size. The environmental conditions are zero wind speed, ambient temperature 20 °C, pressure 1 atm, and relative humidity 50%. The mouth temperature is 34 °C, and the face skin temperature is 32 °C. 779

They called 911. A patrol unit then spotted the suspect near Fremont Street and Maryland Parkway and arrested him.The victim was transported to a local hospital and expected to be discharged later today, according to Watch Commander Lt.

A new health hazard is washing up on shores around the world.“They found a lot of it in Italy. They found a lot of PPE in beaches of Japan and Southeast Asia,” said senior scientist Jennifer Brandon, Ph.D. about personal protective equipment, or PPE. “We’re already finding thousands of gloves and masks as the pandemic continues.” Brandon believes more people are using and also improperly disposing of these single-use plastics and says the litter can last several lifetimes.“I would not be shocked if it’s going to be in the hundreds of thousands in gloves and masks in the next years,” she said.Brandon says with grocery stores no longer allowing reusable bags and restaurants serving to-go orders in Styrofoam containers, this is adding to the problem.This swell of plastic pollution has a chain effect, impacting animals and humans.“That plastic is going to get eaten by animals and those animals are what you eat,” Brandon said. “Sometimes it can break down small enough, it even gets into our water supply and sea salts.”Experts say 30 billion pounds of disposable plastic is dumped into the ocean every year. Now, that number is expected to rise even more due to PPE waste.“We expect that plastic pollution will outweigh fish in the ocean if we don’t take care quick action to prevent that from happening,” said Shelley Luce, president of Heal the Bay, a nonprofit with the mission of keeping water clear and clean.“We do beach clean ups year-round and we generally get 700 to 800 people coming out early on a Saturday morning,” she said.With social distancing orders and many beaches closed due to COVID-19, large group gatherings are no longer allowed in some areas.So, Luce is now encouraging people to clean up what she calls “COVID waste” on their own or within their social bubble.“You can do a cleanup in your neighborhood,” she said. “Pick that trash up off the streets because you know where that's going to go, into a storm drain and out into the ocean.”Luce says there are simple solutions for this worldwide problem: properly dispose of PPE or wear a cloth mask, both of which can help stop the spread of coronavirus without creating an environmental hazard. 2187

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
