A ward at Southampton General Hospital has closed after a member of staff tested positive for coronavirus.
They are now self-isolating at home after working a single night shift on a high dependency unit, which has temporarily closed to new admissions.
The trust says patients and staff who "came into close contact" with the person have also been quarantined.
Jersey's government has confirmed to Channel 103 that no local patients have been affected.
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.
