Anyone arriving into Jersey is now being asked to self-isolate for two weeks.
The Jersey Government introduced new rules at midnight - regardless of what countries you've been to or whether you have any symptoms.
It includes travellers returning from the UK, Guernsey, Europe and the rest of the world.
The advice says solo travellers who live on their own should self isolate, while a family or group who travelled together - or the family of a solo traveller if they live together in the same home - should all go into self-isolation immediately.
It comes after a rise in the number of confirmed cases of COVID-19 in the island to 10, including two people who hadn't been away.
Anyone who develops flu-like symptoms while in self-isolation is being asked to call the government helpline straightaway.
A government spokesman says passengers returning to the island with no symptoms can use public transport to get home, as long as they practice 'social distancing' during the journey and it doesn't last longer than an hour.
Islanders with no symptoms returning home can also use their own vehicles or be collected by a friend or relative at the airport - but the Government says the vehicle should be cleaned after use.
Anyone showing coronavirus symptoms will be transported home by Health officials.
The restrictions don't apply to 'essential workers' coming to Jersey, as the Government says they shouldn't affect its plan to contain the virus and its important to keep the island running. Anyone who develops symptoms of coronavirus, or has any contact with someone who has it will be asked to follow the same public advice and self-isolate.
Visitors to the island are now being told to stay away unless they have the means to self-isolate for 14 days here.
Islanders are still being allowed to travel off-island 'if it is truly essential' - like medical care, looking after vulnerable family members or essential business that can't be done remotely.
If you think you might have the virus, you should self-isolate and call the Health Department's coronavirus helpline:
It's open every day between 8am and 8pm. Calls outside these times, or when the line is engaged, won't be answered straight away - but we're told to leave a message and Health officials will call you back.
Please don't visit your GP or the Emergency Department at the General Hospital if you think you have the virus.
Coronavirus symptoms are similar to that of the flu - a combination of a cough, fever and aching muscles. If you've had any symptoms, even if you haven't travelled abroad, we're being told to self-isolate until they clear up (for a minimum of seven days).
Anyone who has come into contact with a person confirmed to have the coronavirus should stay in self-isolation for at least 14 days.
As of Saturday 28th March, entire households should self-isolate immediately if anyone within that home shows symptoms of coronavirus.
Jersey is in lockdown until 30 April to reduce the spread of Covid-19.
All islanders who are 'not performing essential services' are required to stay at home.
You should only leave home for up to two hours per day to shop for essentials, exercise or get medical treatment if needed. More information here.
On Thursday 26th March, Jersey's government issued stricter measures for over 65s and islanders with underlying health problems - saying they should only leave the house for up to 2 hours a day and only for very limited reasons. Those at severe risk from Covid-19 should adhere to strict self-isolation.
The Government of Jersey is now advising against all non-essential travel on or off the island and all passenger ferry sailings and most airline services have been suspended.
All travellers, including health care workers, arriving in Jersey from anywhere must now self-isolate for 14 days. This is regardless of whether they are displaying flu-like symptoms or not.
The only exceptions to this are non-healthcare, essential workers, if they are not displaying flu-like symptoms.
Guidance for travellers:
- solo travellers, who live alone, should immediately go into self-isolation
- a family or group travelling together should all immediately go into self-isolation
- where a solo traveller is returning to a shared or family home and is not showing any symptoms of infection, they should separate themselves from others in the home in accordance with self-isolation advice for 14 days. Family members should strictly follow social distancing advice
- where a solo traveller is returning to a shared or family home and is showing any symptoms of infection, they should separate themselves from others in the home in accordance with self-isolation advice (for a minimum of 14 days and until a 48 hour period of being symptom free). Household members who have had any contact with the symptomatic patient whilst symptomatic or in the 3 days before symptoms appeared should self isolate as well
During the self-isolation period of 14 days, anyone who develops flu-like symptoms should call the helpline on +44 (0) 1534 445566.
