According to OSHA, employers must "...record and report work-related fatalities, injuries, and illnesses." Standard 29 CFR Part 1904.5 gives details about how to determine whether an illness/injury was work-related. This has always been somewhat complicated, as there are a variety of circumstances that can create gray areas about how or when an employee was injured or taken ill. Given the fast-spreading nature of COVID-19, OSHA recognized the difficulty in determining whether an employee contracted the disease at work. In April, the organization issued a memorandum about when companies should report COVID-19 cases among their employees. At the end of May, OSHA made an important update.
