The Solidarity Trial is an international clinical trial to help find an effective treatment for COVID-19, launched by WHO and partners. It is hoped that one or more of the treatments under trial will result in improving clinical outcomes in COVID-19 patients and save lives. Other trials are on-going around the world in addition to the Solidarity Trial.
Antibody tests can tell us whether someone has had an infection in the past, even if they have not had symptoms. Also known as serological tests and usually done on a blood sample, these tests detect antibodies produced in response to an infection. In most people, antibodies start to develop after days to weeks and can indicate if a person has had recent (IgM type antibodies) or past infection (IgG type). Antibody tests cannot be used to diagnose COVID-19 in the early stages of infection or disease. They also cannot alone confirm immunity or duration of protection from reinfection.
