A study led by Genomics England is trying to find out whether there are genetic factors that mean that some people experience severe symptoms of COVID-19 whilst others experience only mild symptoms. If you have a positive swab test, you can register for this yourself on You can also join this study if your blood test is positive for antibodies to COVID-19.

A cough is one of the most common symptoms of COVID-19.

When we have a cough, often our voice changes as well. Recordings of people’s voices and coughing when they have and don’t have COVID-19 suggests that it might be possible to tell if someone is likely to have COVID-19 just from how their voice sounds. If this worked on large numbers of people, this could be a quick and affordable way to try to find out who has COVID-19 alongside mass testing. You can read more about this study here and you can sign up here (you will need your swab barcode from your most recent visit).
