Brief summary

Characterization of patients with long COVID syndrome including symptoms, medical history and persistent organ damage.

Detailed description

Some people are very hesitant to recover from a COVID-19 infection and present persistent symptoms. The participants still suffer after the acute phase of the infection from shortness of breath, coughing, chest pain or fatigue. Therefore, a special interdisciplinary consultation was built. The consulatation is not only addressed to people who have been hospitalized due to COVID-19, but also to those with mild symptoms during infection. During the consultation hours, personal health data are collected that serves as the basis for this research project.
