If you are isolating together you are required to complete the longer period, in this case 14 days.
Everyone arriving from Category 4 regions and countries is now required to self-isolate until they have received a negative result from a day 13 test. If you decline a day 13 test, you will have to self-isolate for 21 days. Those who choose to self-isolate with someone who has travelled to the Bailiwick will also have to adhere to the same requirement.
If anyone in your household does not agree to have a Day 13 test or, having agreed, does not have a Day 13 test, the whole household must continue to self-isolate until the end of the 21 day period, even if some members of the household receive a negative result from their Day 13 test.
Children under 12 who travel from a Category 4 country or region will also have to be tested at day 13 if they intend to return to a school, pre-school, childcare or nursery setting.
Where a household have decided to self-isolate together, children can only return to a school pre-school or nursery setting once ALL members of that household bubble have received a negative test result from a test undertaken on day 13 or later.
Those who choose to self-isolate with someone who has travelled to the Bailiwick will also have to adhere to the same requirement.
If you are self-isolating with other people in your household, you will need to complete an online form which can be found at www.gov.gg/isolatetogether. This is to ensure that everyone is registered and offered a day 13 test.
