Scientific Guidance on COVID-19 caused by SARS-CoV-2

The Severe Acute Respiratory Syndrome Coronavirus-2 causes the Coronavirus Disease 2019 pandemic. Coronaviruses are enveloped single-stranded RNA viruses, spreads primarily via respiratory droplets and diagnosed by nucleic and serological tests. Clinically progresses from dry cough to respiratory distress and cytokine storm, incubates in 5 days and at risk are old patients with comorbidity. Therapies include acetaminophen for mildly ill and antiviral inhibitors such as remdesivir, alongside passive/plasma and active/vaccine immunization.

Acute Respiratory Distress Syndrome (ARDS) and Systematic Inflammatory Response Syndrome (SIRS) may occur resulting in septic shock and multi-organ failure.
