Travellers are then asked to follow ‘passive follow-up rules’ for the subsequent week. This means being vigilant for covid symptoms, not entering the hospital or any care home, and keeping a record of the places they’ve been and the people they’ve met.

Pictured: As of the 21 April, most of the UK and Jersey has been labelled category 3.
The States of Guernsey has published a list of category 3 countries on its website, including the Cayman Islands, the Isle of Man and Japan, among many others.
Category 4 countries and regions remain, with a negative test required on day one and thirteen before travellers can leave self isolation.
The CCA currently intends to introduce category 2 countries from the 14 May, allowing travellers to leave self-isolation as soon as they’ve had their first test come back negative. They will also be required to adhere to passive follow-up rules for 14 days.
Tests will also come with a new cost from the 14 May of £25.

The categories are determined by the prevalence of covid-19 in the population. This means any country (or in the case of travel to the UK, any region) with a prevalence below 100 cases of Covid-19 per 100,000 population, which also satisfies other Public Health criteria, can be considered Category 3.
‘Category 2’ destinations, when they return, will require a prevalence of below 30 cases per 100,000.
