People arriving in Jersey from red zones will soon have to isolate for 10 days instead of 14.
The government has confirmed the rules are changing in the coming days.
Passengers will be tested on arrival, on day 5, and on day 10. More details will be released next week.
Currently, arrivals from red zones are tested on arrival and exit isolation without a test on day 14.
It was recommended by the Assistant Education Minister Deputy Jeremy Macon to maintain the effectiveness of the current system, while slightly reducing the period of isolation to help returning overseas students and reassure their families.
The triple-testing regime on Day 0, 5, and 10 will be required for all arrivals - no matter whether they come from green, amber or red areas.
"Following medical advice, a revised approach to testing and self-isolation will be introduced, which provides an increased chance of identifying COVID-19 infection while also reducing the period of self-isolation for those travellers arriving from the highest risk countries and regions.
"The new regime introduces PCR tests for ALL arrivals from Green, Amber and Red countries on Days 0, 5 and 10.
"Those arriving from a Green region must isolate until they receive a negative result from their day 0 test, those arriving from an Amber region must isolate until they receive a negative result from their day 5 test, and those arriving from a Red region must isolate until they receive a negative result from their day 10 test.
"Further information on when these new testing and isolation requirements will come into effect will be announced shortly."
