Jersey's Health Department has confirmed the island's first case of coronavirus.
The government isn't releasing any details of the person affected, to protect their identity.
They've been in self-isolation since returning from Northern Italy.
It follows the Channel Islands' first confirmed case being identified in Guernsey on Monday after an islander returned from Tenerife.
Today's case is said to be unrelated to 21 students and staff from Jersey College for Girls going into self-isolation this morning.
Dr Ivan Muscat, Jersey’s Deputy Medical Officer of Health, says:
"Officers from Environmental Health are in the process of contacting the necessary passengers asking them to self-isolate. It does not affect everybody on the flight. If the team do not contact you then there is no need to worry and you do not need to contact the Department or the helpline. We have all the contact details of the people we need to speak to.
"We want to reassure Islanders that the person who has tested positive for coronavirus in Jersey is receiving all the care and medical attention necessary. We are working with the individual concerned to trace any relevant close contacts and therefore ensure that they are managed appropriately.
"We recognise that with the presentation of the first case in Jersey that there may be some concern. However, it is essential that we are open with Islanders about this news, and to ensure that we give the best possible treatment and care to our patient whilst protecting their confidentiality.
"The best thing people can do to help stop the spread of coronavirus is to be scrupulous about hand, surface and respiratory hygiene. Wash your hands frequently. Use tissues to cough or sneeze into and throw them away as soon as you have used them. Keep the surfaces you work on and touch as clean as you can. Those messages will not change."
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.
