SARS-CoV-2

SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) is a coronavirus, which is included in the line of betacoronaviruses. It is an enveloped RNA virus, which was identified as the cause of COVID-19 (coronavirus disease 19) in early 2020. The virus has now formed numerous variants (mutations).

The infectious disease COVID-19 that is caused by SARS-CoV-2 is expressed as a respiratory disease, which involves symptoms such as coughing, a cold and fever, as well as impairment of the senses of smell and taste. In the event of severe disease progression, shortness of breath and pneumonia occur, which may result in fatal respiratory failure.

The risk of severe disease progression increases with age. People with pre-existing conditions are also particularly at risk.

SARS-CoV-2 is spread worldwide. The specific route of transmission of SARS-CoV-2 to humans is not yet clear.

Relevance of pathogen in transmission in endoscopy

  • Gastroenterology: Low

  • Pulmonology: Low

  • Ear, nose, and throat: Low

  • Urology: Not relevant

Relevance for endoscope surveillance

  • Low or moderate concern organism

Transmission route

The transmission of SARS-CoV-2 occurs primarily via droplets/aerosols. In this case, particles containing the virus created when breathing, coughing, talking, singing and sneezing are absorbed by another person via respiration.

Transmission via direct contact with contaminated hands and contaminated surfaces can also not be ruled out, but based on current knowledge this might be less significant.
