Long COVID
en.wikipedia.org/wiki/Long_COVID
Long COVID or long-haul COVID is a series of health problems persisting or developing after an initial COVID-19 infection. Symptoms can last weeks, months or years and are often debilitating.[3] The World Health Organization defines long COVID as starting three months after infection, but other definitions put the start of long COVID at four weeks.[2]
Long COVID is characterised by a large number of symptoms, which sometimes disappear and reappear. Commonly reported symptoms of long COVID are fatigue, memory problems, shortness of breath, and sleep disorder.[5][6][7] Many other symptoms can also be present, including headaches, loss of smell or taste, muscle weakness, fever, and cognitive dysfunction and problems with mental health.[7][8] Symptoms often get worse after mental or physical effort, a process called post-exertional malaise.[5] There is a large overlap in symptoms with ME/CFS.[2]
The causes of long COVID are not yet fully understood. Hypotheses include lasting damage to organs and blood vessels, problems with blood clotting, neurological dysfunction, persistent virus or a reactivation of latent viruses and autoimmunity.[3] Diagnosis of long COVID is based on suspected or confirmed COVID-19 infection, symptoms and by excluding alternative diagnoses.[9][10]
Estimates of the prevalence of long COVID vary based on definition, population studied, time period studied, and methodology, generally ranging between 5% and 50%.[11] Prevalence is less after vaccination.[12] Risk factors are higher age, female sex, having asthma, and a more severe initial COVID-19 infection.[4] As of 2023, there are no established disease-modifying treatments.[3][8] Management of long COVID depends on symptoms. Rest is recommended for fatigue and pacing for post-exertional malaise. People with severe symptoms or those who were in intensive care may require care from a team of specialists.[13] Most people with symptoms at 4 weeks recover by 12 weeks. Recovery for those still ill at 12 weeks is slower or plateaus.[13] For a subset of people, for instance those meeting the criteria for ME/CFS, symptoms may be lifelong.[3]
