Blood donation Current Affairs - 2020
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 idea of the method is to inject plasma with antibodies into critically ill patients for them to gain immunity against the virus.
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 inject 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.
