What is plasma therapy? Does it work against the coronavirus????


Plasma Therapy

Several studies have already started in different parts of the world to test the effectiveness of convalescent plasma therapy in treating COVID-19 patients.
The idea behind this therapy is that immunity can be transferred from a healthy person to a sick using convalescent plasma.
Convalescent plasma refers to plasma from recovered COVID-19 patients.

How does it work?


So in this therapy, blood is drawn from a person who has recovered from the disease and the serum is separated and screened for virus-neutralizing antibodies.
When attacked by a pathogen, our immune systems produce antibodies and in this therapy these antibodies from recovered patients are used to treat other sick people.

Differences in mild and severe cases




Immunity develops early in asymptomatic or persons with mild symptoms, while it develops later in severe and critically-ill COVID 19 patients,

History of the therapy

he concept of this therapy dates back more than a century, when similar treatments were used during the Spanish flu pandemic of 1918, a diphtheria outbreak in the 1920s, a flesh-eating bacteria epidemic in the 1930s, and during other outbreaks of infectious diseases. It was tried most recently for Ebola. The effectiveness of the therapy has varied.
