How many tests do people need to get? 1 - Passengers get their first mandatory test within 72-hours of their departing flight. (When they arrive - from a country that isn't on the list of 33 'red' countries that must quarantine in a hotel - they must isolate for 10 days) 2 - On day two of self-isolation, a Covid PCR test will be administered. The tests will be posted to the traveller, it is understood. 3 - An optional test can be taken on the fifth day of at-home isolation. If it comes back negative, the traveller will no-longer have to self isolate. 4 - Another mandatory test will be carried out on day eight.
