A new report found that 40% of America’s COVID-19 deaths could have been prevented, the Lancet Commission on Public Policy and Health found that many people didn’t take the pandemic seriously at the beginning. Commission co-chair Dr. Steffie Woolhandler says public health measures such as mask wearing and physical distancing could have saved lives. However, Woodhandler says former President Donald Trump failed to create a national response, instead leaving crucial decisions to states.

Cases of chemicals from hand sanitizers getting into young eyes increased 7-fold between April 1 and Aug. 24, 2020, compared to the same period a year earlier. Weber knows about the dangers of eye exposures to hand sanitizer as she’s had these calls come into the center. To keep kids safe, Weber says parents should keep hand sanitizer out of reach of younger children. Weber says you should call the nationwide poison control hotline at 1-800-222-1222 if your child gets hand sanitizer in an eye.

Dogs may be able to be trained to detect COVID-19, according to a study published on Thursday. Detection dogs, like those that sniff drugs or explosives at airports, are taught to sniff for certain infections and diseases. Now, some countries are exploring the possibility of using those types of dogs as a rapid, reliable and relatively cheap way to pre-screen people for COVID-19. Six dogs had their sniffing abilities put to the test and performed dozens of trials, with a success rate of 76-100%. The study was published Thursday in the peer-reviewed journal PLOS ONE.

Researchers have found that ultrasounds give a better indication of which COVID-19 patients have a higher risk of dying. Doctors at hospitals across the Mount Sinai system in New York looked at echocardiograms, or ultrasound scans of the heart, for 305 COVID-19 patients and 190 of those had structural heart damage. The scans gave doctors an indication of which patients had the highest risk for death.

The research gives further evidence blood type may play a role in someone’s susceptibility to infection and just how serious their illness is. The reasons for this link aren’t clear and experts say more research is needed.

Scientists at Florida Atlantic University are experimenting with different nonmedical masks to find the most effective face covering to help stop the spread of COVID-19. They "delivered" a sneeze or cough from a mannequin head wearing varying face coverings and used lasers to detect respiratory droplets. Droplets from a bandana-covered cough traveled 3 feet. With a folded cotton handkerchief, droplets traveled 1 foot, 3 inches, and with the cone-style masks, they traveled about 8 inches. Stitched-quilting fabric masks were the most effective, with droplets traveling 2.5 inches.
