In order to be placed in the category, the region must have a covid prevalence rate of more than 100 per 100,000 for seven consecutive days. Arrivals from Category 4 countries and regions will be able to take a test on arrival with self-isolation for 14 days.
Jersey also joins the rest of Great Britain – apart from the Isle of Man and Scottish Islands – in the highest risk category.
It comes as the number of recorded covid cases in Jersey hit 152 this afternoon. 89 are symptomatic and 63 are not displaying symptoms. No one is in hospital.
Meanwhile, Guernsey remains on Jersey’s green list.
Arrivals from green zones must have a covid test on arrival and on day 5, and self-isolate until their first negative result.
