As Covid-19 cases have climbed as part of a late-summer uptick, right-wing influencers and conspiracy theorists have responded by stoking fears about mass lockdowns and spreading unsubstantiated new ideas about Covid-19’s links to world events. “Do they want Covid measures back to put us on war footing in preparation for the war with Russia?” Jack Posobiec, a right-wing personality, said to more than 150,000 followers on his Telegram channel. ... The use of “plandemic” and “scamdemic” — two terms describing Covid-19 as a ruse — rose sharply in August on right-wing websites, according to data from Pyrra, a company that monitors threats and misinformation on alternative social networks.

Children with a high genetic risk of developing type 1 diabetes see an increase in islet autoantibodies, which develop against pancreatic β-cell proteins, shortly after infection with SARS-CoV-2, illustrating a temporal relationship between COVID-19 and islet autoantibodies not seen with influenza. The study was published in JAMA. ... Of 885 children who agreed to participate in the study, SARS-CoV-2 antibodies developed in 170 children at a median age of 18 months, and islet autoantibodies developed in 60 children. Six of the 60 children tested positive for islet autoantibodies and SARS-CoV-2 antibodies at the same time, and six tested positive for islet antibodies after having tested positive for SARS-CoV-2 antibodies 2 to 6 months earlier.
