“Targeted action” is being taken against more than 100 local outbreaks of coronavirus every week, Health Secretary Matt Hancock has said.
Writing in the Daily Telegraph, Mr Hancock said increased testing meant officials could now be “targeted” in their response.
His comments came after 73 cases of Covid-19 were confirmed at a farm in Herefordshire.
Around 200 workers have been told to self-isolate following the outbreak.
It is now two weeks since Mr Hancock announced Leicester would be the first city in the UK to be put under a local lockdown. Restrictions are expected to be reviewed this week.
But he has stressed that most measures to contain the coronavirus will not involve a whole city but instead would centre on a much smaller area,
