Despite the fact that in most cases, coronavirus infection is asymptomatic or mild, in some people, coronavirus can cause serious lung damage, which doctors have not yet encountered before this epidemic. Its main feature is the rapid development of respiratory failure,which can cause death. Doctors treat this virus in combination with several methods of treatment, and one of them is treatment with immune plasma. Patients with weak immune systems do not produce antibodies. Also, to create passive immunity for patients, doctors transfuse the blood of those who have been ill with coronavirus and, thanks to donation, help overcome the virus.
