In the United States, 60% of adults have at least one chronic health condition: illnesses or conditions like chronic pain and fatigue that last at least one year and require ongoing management or restrict an individual’s activities. These numbers don’t include Covid-19 “long-haulers,” or the 10% of those who experience lingering symptoms, such as difficulties with memory and thinking (“brain fog”), fatigue, racing heartbeat, gastrointestinal problems, or chest pain for weeks, months, or longer after contracting the virus.
