Tests to screen Covid-19 coronaviruses are carried out at home in Germany. Almost 4,500 people were randomly selected from Munich to participate in a study of unprecedented scale. No sample taken from the nose or mouth but a blood test to detect the presence of antibodies to Covid-19.
Those tested do not show symptoms of the virus but may have been infected without realizing it. The test will find out. The objective of the tests is to find out who is no longer able to transmit the disease. Some researchers are already imagining certificates of immunity, like a passport to get out of confinement. Several methods of blood tests are being developed. A clinic has received a machine that can process around 100 tests per hour. It will be operational in a few days.
