Anyone travelling through the UK to Jersey from a high-risk country will be legally required to quarantine in Britain, the UK's Health and Social Care Department have confirmed.
The UK's mandatory 10-day isolation period comes into force on Monday 15 February for anyone arriving from 33 countries on the 'red list'.
People will be required to quarantine in government-approved accommodation such as hotels.
This also applies to travellers who have passed through any high-risk country within the last 10 days.
Passengers travelling to Jersey via the UK from places not on the high-risk list will be allowed through without having to self-isolate but must still abide by all national lockdown rules.
All travellers must still isolate on arrival in Jersey until a Day 10 negative test.
People arriving in the UK from Jersey do not need to quarantine because Jersey is part of the Common Travel Area.
