Chat about Novel Coronavirus - 2019-nCoV - COVID-19

Agreed.

French embassy and foreign office say this:

1. What are the requirements for the test to be carried out before travelling to France ?
   All travellers aged 12 or over must present a PCR or antigen test less than 24 hours old prior to their departure.

2. What are the requirements for the test to be carried out in France ?
   All travellers aged 12 or more must self-isolate for 10 days at the address stated in the éOS form.

Their interior ministry page says this:

If you are travelling from the UK, whether you are vaccinated or not, you must present a PCR or antigen test dated less than 24 hours. The departure of the first flight in case of connecting flights. Children aged below twelve years are exempt from testing.
You must equally present:
A sworn statement certifying the absence of COVID-19 symptoms and of any contact with a confirmed case of COVID-19;
A sworn statement that you will take an antigen test or undergo a medical examination that may be performed on arrival in metropolitan France;
A sworn statement to self-isolate for 10 days and take a virological screening test (PCR) after the isolation period (cf. above).
All incoming travellers from the UK shall also be required to register, prior to their departure, on a digital platform, specifying the address where they will be staying in France. This platform will be used to generate prefectural decrees requiring all travellers, both vaccinated and unvaccinated, to self-isolate in a place of their choice.

This isolation obligation can be waived after 48 hours, subject to presentation of a negative test result (PCR or TAG).

I think all this is due to some bullet point formatting issue.

So according to the above, my kids didn’t need to fill in a eOS locator form.
But because the forms exist, the local police don’t want to release them from isolation, because their names are on the system, and they haven’t got LFTs on file for them. Even though they are exempt.
