Other skin diseases may be associated with malignancy in a subset of patients.

The transmission dynamics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Wuhan and Hubei Province differ considerably from those in the rest of China. In Hubei province SARS-CoV‑2 led to a dramatic outbreak. ⋯ Despite travel restrictions SARS-CoV‑2 was detected in other provinces in the following weeks. Consistent and intensive identification and isolation of infected persons ("containment") was able to prevent an outbreak outside Hubei province, providing an example for the control of SARS-CoV‑2.

Coronavirus disease 2019 (COVID-19) continues to pose a major global threat. Although a wide range of organ manifestations have now been described, the respiratory system remains in the forefront in terms of the course of infection. Severe pneumonia can develop and is generally prognostically relevant. ⋯ This is followed by a description of symptoms, which develop in three phases. With regard to treatment, supportive and intensive care approaches are discussed, including O2 administration and (non-)invasive ventilation. The article concludes with a summary of the insights gained into pharmacological therapies: thrombosis prevention on the one hand, and specific antiviral and immunomodulatory therapies (remdesivir, tocilizumab, anakinra, dexamethasone) on the other.
