Conditions

COVID, SARS-CoV2

Brief summary

Approximately 15% of patients with SARS-CoV-2 infection / COVID-19 develop a severe clinical course. This leads to hospitalization and potentially life threatening complications such as pneumonia and respiratory failure. Predictors for early detection and risk stratification are urgently needed. Moreover, only scarce information is available for long-term follow-up and late complications associated with infection. We therefore aimed to find predictors for severe courses of the novel disease as well as to establish strategies for therapeutic monitoring and follow-up.
