Plasma Exchange and COVID 19.

Coronaviruses (CoVs) were first described in the 1960s as a broad subfamily of RNA viruses affecting both human and animals. In humans, infections caused by members of this family primarily involve respiratory and/or gastrointestinal system, with a wide range of clinical manifestations [1]. Since the beginning of the 21st century, there have emerged two highly pathogenic and, at times, fatal in humans, members of the corona-family: Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) that was the etiological agent of a severe respiratory endemic disease in China during 2002–2003 and Middle East Respiratory Syndrome Coronavirus (MERS-CoV) that was responsible for a similar outbreak in the Middle East during 2012-today [2].
