An asthma organization warned against participating in a social media trend that suggests people can treat or prevent COVID-19 by inhaling hydrogen peroxide through a nebulizer. The Asthma and Allergy Foundation of America (AAFA) said the trend was "concerning and dangerous," according to a blog post on its website. "DO NOT put hydrogen peroxide into your nebulizer and breathe it in," the AAFA's blog said. "This is dangerous!"
