ABSTRACT
Most people recover completely after an acute infection with the novel corona virus SARS-CoV2. But some people continue to experience symptoms after their recovery. This phenomenon is called post-acute or long-COVID (from week 4 after the infection up to week 12) and persistent post-COVID (symptoms for effects that persist 12 or more weeks after onset). The exact processes that cause long COVID remain unknown.Most of those patients suffer from long-term symptoms of lung damage, including breathlessness, coughing, fatigue and limited ability to exercise. Today, 18 months after the first infections in Europe we have access to the first practical guidelines for the long-/post-COVID syndrome. Further on first prospective studies analysing the incidence of post-COVID are now available.In this review we will discuss some questions about treatment and follow up of patients suffering from pulmonary sequelae after their COVID-19 infection, based on the actual literature.
