A UK city is being added to a new tier in the system – Tier 1 Plus.
Bristol will enter the tier, which straddles the cusp of tier one and tier two, according to the city’s Mayor.
The South West city is the first to be added to the new band of coronavirus restrictions and measures.
As part of Tier 1 Plus, Bristol will face tighter enforcement, more local control over test and trace, targeted focus on working adults (aged 30 – 60) and an introduction of Covid marshals across the city.
It is a last ditch attempt to avoid Bristol entering tier 2 or tier 3, according to reports.
Public Health Bristol official Christina Gray added: “In order to keep open, we need to drive down infections.”
Bristol’s numbers are now higher than the English average, at 340.7 per 100,00 population.
Professor Neil Ferguson, the scientist whose modelling prompted the UK-wide lockdown in March, told the PA news agency that measures in Tier 2 and Tier 3 areas are “unlikely to cause daily cases and deaths to fall rapidly”.
He said modelling suggests this could leave the country with high caseloads for several months.
A former chief scientific adviser to the Government said the number of people in hospital with Covid-19 could more than double within weeks.
Prof Ferguson, from Imperial College London, told PA: “The concern at the moment is that even if the measures adopted in Tier 2 and Tier 3 areas slow spread in the next few weeks, they are unlikely to cause daily cases and deaths to fall rapidly.
“Modelling from all the academic groups informing Sage suggests that this could leave the country with high levels of Covid circulation, healthcare demand and mortality for several months, at least until spring 2021.”
