CHOIS is a study looking at potential long-term health problems and immune responses in NHS staff members that have recovered from COVID-19. This is such a new virus that we don’t know how the virus may affect people’s health in the longer term and whether long-term immunity is produced. We are asking staff members to help with this study, whether or not they have had COVID-19 infection. If you have already had the swab or antibody (blood) test you could still help with the study regardless of the result.
The study is taking part in the Centre for Clinical Infection at James Cook
