Study summary

A study on patients who are hospitalized and tested positive for COVID-19 or have a typical CT image of COVID-19 infection, to establish if omega-3 Polyunsaturated Fatty Acid (PUFA) supplementation by intravenous route is a possible treatment option in COVID-19 with minimal risks to the patients.
