Almost two years into the Covid-19 pandemic, hundreds of millions of people around the world have been infected. Although most recover quickly, some do not. These patients experience persistent symptoms, a condition now called Long Covid. It can affect people’s ability to work and carry on with life’s activities. To meet the challenges brought on by this emerging syndrome, the Long Covid initiative at the Brown University School of Public Health brings together researchers, clinicians, and experts in policy as well as strategic communications, to rapidly study and communicate the significant impact of Long Covid on people, communities, workplaces, healthcare, and society as a whole.
Long Covid refers to the signs and symptoms that continue or develop after a person’s initial Covid-19 infection. As many as 30 to 50% of people who had Covid-19 report experiencing at least one symptom that lasts weeks or often even months after the initial infection. For people with more severe Covid-19 infections, up to 80% may experience new or ongoing symptoms. This is often referred to as Long Covid. Other names include “long haul covid”, “post-acute Covid-19 syndrome” and “persistent Covid symptoms”.
Long Covid can cause a wide range of symptoms, lasting for different lengths of time, and varying in severity. For some, symptoms may be mild while others might become increasingly incapacitated. Symptoms may persist after initial infection, return after a period without symptoms, or emerge following an initial infection without symptoms.
Common symptoms of Long Covid are:
The CDC recommends that people visit their primary care doctor if they experience new or ongoing symptoms four or more weeks after their COVID-19 diagnosis. Patients and their doctors may develop a plan to help manage symptoms and improve quality of life. Additionally, doctors may encourage patients to seek treatment at a rehabilitation center or post-Covid care clinic. Rehabilitation has been useful among elderly patients with Covid-19 for improving respiratory function, quality of life, and anxiety.
Among people with severe Covid-19, as many as 50-70% report impaired quality of life three to six months after hospitalization. Other reports suggest that some people with Long Covid may have to reduce their work hours or modify their duties due to persistent health issues. Additionally, financial hardships due to the initial COVID-19 infection may be compounded by new costs and lost income due to Long Covid.
