A new study suggests misguided antibodies created as a response when someone is infected with the coronavirus could be the cause behind both more severe COVID-19 symptoms and those who report having symptoms for months after initially recovering.Researchers at Yale University found that COVID-19 patients they studied had high levels of antibodies that had turned on them; these wayward antibodies blocked antiviral defenses, wiped out helpful immune cells and attacked the body in several areas including the brain, blood vessels, liver and gastrointestinal tract.“Covid-19 patients make autoantibodies that actually interfere with immune responses against the virus,” Aaron Ring, an immunobiologist at Yale and senior author on the study, told The Guardian.Autoantibodies are antibodies that attack the body’s own proteins by mistake and disrupt their normal functions.“We certainly believe that these autoantibodies are harmful to patients with Covid-19,” said Ring. He added that the harmful effects of these autoantibodies could continue well after the initial infection has been overcome. He said antibodies can last for a long time, and if they are misguided in their attacks, the effects of their attacks on the body could also last a while.The study, which has yet to be peer reviewed and formally published, looked at antibodies from 194 COVID-19 patients and hospital workers with a range of symptoms and severity of symptoms.Other conditions, like lupus, multiple sclerosis and rheumatoid arthritis, are also made worse by the immune system malfunctioning and attacking the body. 1600

A man was arrested for battery and disorderly conduct for allegedly spitting on a boy and telling him he “now has coronavirus.”Jason Copenhaver, 47, walked up to the boy on Sunday at a restaurant in Treasure Island, Florida. He asked the boy if he was wearing a face mask, according to the police report. The boy said yes, and Copenhaver told him to take it off and asked to shake his hand.The boy refused, according to police, then Copenhaver grabbed the boy’s hand and said “you now have coronavirus” while standing close enough to the boy for spit to land on his face.The police report also notes that Copenhaver was believed to be under the influence of alcohol, and tried to hit an employee at the restaurant who asked him to sit down. Staff was able to walk him outside and hold him on the ground until police arrived.Once in custody, Copenhaver told police he doesn’t know if he has coronavirus and has never been tested. 936

A nurse in Illinois is no longer employed after posting on social media about running over protesters amid massive unrest gripping the country.According to WMBD-TV, the nurse is longer associated with OSF HealthCare after making “insensitive comments” on social media. It’s unclear if she was fired or quit on her own accord.“As previously shared, a Facebook comment made by one of our Mission Partners did not align with our values,” a spokesperson for OSF HealthCare told WMBD on Friday. “That person was immediately suspended, and as of today, is no longer with our organization. Words and actions that seek to marginalize or harm others have no place within our Ministry.The post read, “If I’m driving down the road with my horse trailer behind me. No matter who you are. If you’re in the road ‘protesting’ I will run you over. I will not stop. I will not brake. I will not hesitate. I’d rather go to jail than have you injure or scare my horses.”A number of Twitter users brought the May 31 Facebook post to the attention of OSF HealthCare in recent days. “Thank you for bringing this to our attention. We're aware of the situation, and our HR team is addressing it,” the organization said before announcing the nurse no longer was an employee. 1257
