Information and public services for the Island of Jersey

L'înformâtion et les sèrvices publyis pouor I'Île dé Jèrri

COVID-19 data (FOI)

COVID-19 data (FOI)

Produced by the Freedom of Information office
Authored by Government of Jersey and published on 24 August 2022.
Prepared internally, no external costs.


According to the data provided by yourselves at: 

Coronavirus (COVID-19): Number of coronavirus (COVID-19) cases, tests and inbound travel (

Jersey, over a 2.5 year period, has tested a total of 1067252, nearly 9x its population.

The data also suggests that from the test cases 1009519 had returned positive, again 9x its populations.

Breaking the data down i can see:

2020 = 232k positive cases

2021 = 682k positive cases

2022 = 327k positive cases

I understand that not everybody on island is contributing towards the statistics and taking testing/isolation in home without advising the government. therefore for each year listed above I would like to know:


of the island's population what % of people are registered at the testing centre vs the % of never attended/registered for a test.


of the people registered how many times have they returned a positive case, i.e.,

i) 1 positive in the year 2020 or 2021 or 2022

ii) 2 positives ...

iii) 3...

iv) 4...

v) 5...

vi) 6...

vii) etc...


Please provide a breakdown of the vaccination status of each positive case at the time of testing 


Please note, the figures stated in the request have been erroneously calculated (summing of cumulative figures) and should read: 

2020 = 2,760

2021 = 16,662

2022 (up to 18 August) = 39,311 

In total, Jersey has recorded 58,733 cases since March 2020 not 1,009,519 as stated in the question.


Information is not held in the format requested (the number of unique positive cases is calculated and not the number of unique tests and which have not been calculated as a proportion of Islanders). Article 3 of the Freedom of Information (Jersey) Law 2011 applies.


Information in respect of reinfections is published monthly on Article 23 of the Freedom of Information (Jersey) Law 2011 has been applied.
