Donor’s Blood May Help Recipient Fight COVID-19

New York: Blood from people who have recovered from COVID-19 may help treat or prevent the disease in others.

Scientists are preparing to see if injecting patients with the clear liquid part of blood, known as plasma, from patients who have recuperated from coronavirus infection can halt the virus.

It’s an age-old treatment, used for more than a century against various outbreaks, from the 1918 influenza pandemic to measles in the 1930s to Ebola in 2014.

When patients recover from a disease, their blood contains antibodies to the germ that caused it. Antibodies are like the immune system’s warning flags. When a germ infects a patient again, those warning flags draw the immune system’s attention to the invader, and the body can fight it off.
