UK Covid-19: Saliva swab test hoping to ‘bring confidence’ to travellers

Daily Mail published this video item, entitled “UK Covid-19: Saliva swab test hoping to ‘bring confidence’ to travellers” – below is their description.

The first test to detect ‘active’ Covid from a saliva swab rather than ‘harmless viral fragments’ is to be rolled out across the UK. The KnowNow antigen test mimics the surface of a human cell to identify the virus and only recognises ‘infectious’ or ‘active’ Covid. By comparison, PCR and lateral flows are susceptible to picking up ‘harmless viral fragments’ – meaning some people test positive and have to isolate despite not having the virus. The test is designed to mimic the experience of brushing your teeth rather than sticking a swab up the nose and swiping the back of the throat, and is more accurate than its predecessors.
