A recent study by the U.S. Centers for Disease Control and Prevention found that 6% of more than 3,000 health care workers who were tested had antibodies to coronavirus. Still, after being retested 60 days later, 28% of them had antibody levels so low they were no longer detected."These results suggest that serology testing at a single time point is likely to underestimate the number of persons with previous SARS-CoV-2 infection, and a negative serologic test result might not reliably exclude prior infection," the authors of the study said.According to the CDC, blood samples were taken from 3,248 frontline health care personnel at 13 hospitals between April 3- June 19, 2020.194 of those healthcare workers had detectable antibodies to COVID, the agency said.Participants with higher initial antibody responses were more likely to have antibodies detected at the follow-up test than were those who had a lower initial antibody response, the study concluded.The authors added that the study shows that the window is limited for collecting potentially useful "convalescent plasma" from the blood of patients who have fought off COVID-19. 1151

A viral video showing security camera footage taken in Chula Vista, California on Halloween night may help restore your faith in the honor system. Kim Manalo's family joined the throngs of trick-or-treaters racing door-to-door in their neighborhood.  Manalo wanted to keep the spirit of Halloween alive at her home while they were out, so she left a bowl filled with candy outside their door with a note asking people to help themselves.  Her hope was that people would leave a treat for the next candy-seeker."We came home to an empty bowl and hoped there weren't greedy kids that didn't leave some behind for others," Manalo wrote on her post.She studied security footage to see if perhaps someone grabbed more than their share of goodies. What Manalo found on her security camera video was a surprise that almost made her cry."Instead we found this clip of a wonderful soul who shared some candy from his own bag to keep the halloween spirit going for other kids," Manalo she wrote.The video shows one of the boys reach into his bag and place some of his own candy in the bowl for the next trick-or-treaters. “He didn't even know the camera was there,” Manalo said. “None of his friends knew and to take that second out of his time from his own stuff just really warmed my heart.”San Diego-based KGTV posted the surveillance video on Facebook after Manalo's friend shared the footage with reporter Joe Little.  The video has garnered hundreds of reactions, shares, and comments."If only all of us raised our children to be so thoughtful even when no one is seemingly looking. He will change the world someday if he keeps it up," wrote Jeremy Ellis.The identity of the thoughtful boy remains a mystery, but numerous adoring Facebook fans are looking for clues to thank him for inspiring the spirit of community. 1941

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
