The Food and Drug Administration of the United States has approved the use of Convalescent plasma collected from patients recovered from COVID-19 to treat seriously ill COVID-19 patients.
The Convalescent plasma treatment had earlier been studied during the outbreaks of 2003 SARS-CoV-1 epidemic, 2009-10 H1N1 influenza virus and 2012 MERS-CoV epidemic.
The treatment is mere collection of plasma from a COVID-19 recovered patient and injects them into a critically ill patient of COVID-19.
The main role of plasma is to carry hormones, nutrients and proteins to different parts of the body.
