LONG Covid is a persistent state of ill health that continues for more than three months after Covid-19 infection. Patients with long Covid have reported experiencing different combinations of symptoms such as fatigue, shortness of breath, coughing, anxiety, cognitive impairment or brain fog, and muscle pain, which become worse after physical activities.
These symptoms could be driven by a direct effect of virus infection and might be explained by several hypotheses, including abnormal immune response, hyper activation of the immune system, or autoimmunity. Additionally, indirect effects such as reduced social contact, loneliness, incomplete recovery of physical health, and loss of employment could affect psychiatric symptoms.
