Home Secretary Priti Patel announced quarantine plans for new arrivals to the UK, which will be in place from Monday, June 8. Those arriving in the UK by plane, rail, road and air will be subject to a 14-day quarantine.
All arriving passengers will be required to fill this in to provide contact and travel information so they can be contacted if they, or someone they may have been in contact with develops the disease.
They will also be contacted throughout the 14 day period to make sure they are adhering to the quarantine guidelines.
A breach of self-isolation would be punishable with a £1,000 fixed penalty notice in England or potential prosecution and unlimited fine.
Anyone who fills the form in wrong could also face fines of up to £100.

Ms Patel said she was imposing quarantine plans for new arrivals at the time “it will be the most effective”.
She told the daily Downing Street press conference: “The answer as to why we’re bringing in these measures now is simple: It is to protect that hard-won progress and prevent a devastating resurgence in a second wave of the virus.
“As we are taking this action, we are taking it at a time that it will be the most effective.”
She said passenger arrivals have been down 99 percent compared to the previous year but now the peak has passed, steps to “guard against imported cases” must be imposed.
“We are not shutting down completely. We are not closing our borders. People need to recognise that.
“What we are seeking to do is control the spread of the virus because we do not want a second wave of this virus.”
The rules will be reviewed every three weeks, so are expected to be in place until at least June 29.
Officials would not answer on whether the measure will be in place long-term.
When questioned about holidays, Ms Patel reiterated only essential travel is permitted.
She said: “The advice is not about booking holidays, right now.
“We are bringing in these measures for very clear reasons, as I have outlined.
“The other point to note is that advice from Government and the Foreign and Commonwealth Office is you’re not to travel and to please follow the advice they are putting on their website, which is nothing but essential travel.
“This is absolutely not about booking holidays. We want to avoid a second wave and that is absolutely vital.”
