The term "rehabilitation" refers to a "series of interventions meant to improve functionality in people with health problems as they interact with their environment." Disease (acute or chronic), injury, or trauma are examples of health problems, which can also include pregnancy, ageing, stress, congenital anomaly, or genetic predisposition. COVID-19 poses substantial difficulties for rehabilitation services all throughout the world. Rehabilitation services are routinely among the most severely affected health services as a result of the pandemic. COVID-19, on the other hand, actually increases the need for rehabilitation – both for patients who are severely ill with the disease and for those who are still suffering from the long-term effects of their condition. The requirement for rehabilitation is now largely unmet. More than half of people in several low- and middle-income nations do not obtain the rehabilitation services they require. The COVID-19 pandemic has wreaked havoc on rehabilitation programmes, as well as other health services.
