All passengers arriving in Britain from countries not on the Covid hotspot list could have to take four tests during their isolation period, it emerged last night. 'When you arrive into the UK you will have to take two tests during your ten-day isolation,' a Government source explained. PCR tests can take up to three days to identify positive cases. Part of the delay to starting the hotel quarantine measures is due to identifying buildings which fit those requirements, sources said. Polymerase chain reaction (PCR) tests involve a patient swabbing their nose and throat and can take up to three days to get results.
