In March 2020, the World Health Organization (WHO) declared the COVID-19 outbreak to be a pandemic, and a year later more than 120 000 000 people are confirmed with the disease. The disease has caused more than 2 700 000 deaths globally. Norway has a low mortality rate compared to rest of the world. However, a large proportion (10-33%) of the patients worldwide have reported persistent symptoms, such as dyspnea, reduced exercise capacity, loss of taste/smell and fatigue months after the infection. Persistent symptoms are also found in younger populations and in persons with an initially mild disease.
The intervention will take place at "Helse i Hardanger" (HiH)(Health center in Hardanger, Norway). The participants will stay for a 3 -day rehabilitation intervention, if needed, another 1 or 2-day stay will be offered about a month later. The concentrated treatment will be given by an interdisciplinary team, including doctors, physiotherapists, nutritionists, pharmacists, psychologists/psychiatrists, and nurses. The intervention is an individualized group treatment based on behavioural change.
