London CNN  — 

UK Prime Minister Boris Johnson drastically ramped up the country’s response to coronavirus on Monday, after a weekend of confusing briefings.

The policy shift comes after Johnson’s response to the crisis came under very public criticism, and sparked suggestions that he is not taking it anywhere near seriously enough.

Only four days ago, Johnson asked those with coronavirus symptoms to self-isolate for seven days. On Monday, he said entire households where someone was displaying signs of the illness – a fever or a new, persistent cough – should now stay put for 14 days.

“Now is the time for everyone to stop non-essential contact with others and to stop all unnecessary travel,” he added, encouraging people to avoid pubs, clubs, theatres and restaurants.

With particular focus on the elderly, pregnant women and those with pre-existing health conditions, Johnson said people who were considered medically vulnerable should be shielded from other members of the public for 12 weeks.

Finally, he said that the emergency services would no longer be present at large gatherings such as sporting events and music concerts.

UK approach to virus criticized

The move comes after a weekend of strange briefings from various government officials that seemed to directly contradict what Johnson had said last week.

Last Thursday, flanked by the UK’s chief medical officer and chief scientific advisor, Johnson explained that even as the nation upped its response to the virus, it would not be shutting schools or banning mass gatherings. People displaying symptoms were asked to self-isolate for a week. Beyond that, there were no further measures for social distancing. Just wash your hand and be sensible.
