The infected individuals, who recently travelled into the Island are in isolation and are described as ‘well’.
Contact tracing team members are contacting all of their direct contacts and any of those who test positive.
In a statement, Dr Ivan Muscat, deputy medical officer of health, said: ‘While this variant is more transmissible than other variants, Public Health England has said there is no evidence that it causes more severe disease, and studies show that the vaccines in use in Jersey and the UK are effective against it.
‘Our vaccination programme, in conjunction with public health measures, regular testing, and contact tracing, remain key to controlling this virus. More than 50% of adults in Jersey are now fully vaccinated.
He added: ‘This reduces their risk of contracting or passing on the COVID virus by some 80 to 90% depending on the specific variant. Adults who have had one dose of vaccine are also afforded some protection, but not to the same extent as those who have received two doses.’
Dr Muscat added strongly encouraged Islanders to continue to adhere to public health guidelines and called on anyone eligible for testing to take it up.
