When we reduce our day-to-day contact with other people, we will reduce the spread of the infection. That is why the government is now (23 March 2020) introducing three new measures.
Requiring people to stay at home, except for very limited purposes
Closing non-essential shops and community spaces
Stopping all gatherings of more than two people in public
Every citizen must comply with these new measures. The relevant authorities, including the police, will be given the powers to enforce them – including through fines and dispersing gatherings.
These measures are effective immediately. The Government will look again at these measures in three weeks, and relax them if the evidence shows this is possible.
