Boris Johnson Steps Up Plans To Tackle Coronavirus As Criticism Mounts Jamie Dettmer British Prime Minister Boris Johnson will step up government action this week in a bid to slow the spread across Britain of the potentially deadly coronavirus by accelerating plans to make the elderly stay at home -- possibly for months -- and for whole families to self-quarantine when any family member displays COVID-19 symptoms. The acceleration of planned new social-distancing rules marks the third policy reversal by Johnson in the past four days. The move comes after hundreds of scientists accused the government in an open letter of "risking many more lives than necessary" by delaying the introduction of more restrictive social-distancing measures. They are urging the government to start locking-down virus hotspots, close schools and order the cessation of flights from other countries affected by the outbreak, as other European countries and the U.S. have done. .
