Under the grandeur of Preston market’s Victorian canopy, the nervousness wrought by a resurgence of Covid-19 is not far away. Amid the fruit, veg and dairy stalls, all the shoppers and stallholders are wearing masks, keeping their distance. “Everybody seems to be sticking to the rules as much as they can,” said Gary Quinn, the landlord of the Orchard pub. “People haven’t been very clear on what is allowed, but I haven’t seen people acting maliciously. People are trying their best.”

Despite the efforts, the city is again seeing a resurgence of the virus, with 324 cases per 100,000 in the past seven days. Like dozens of other local authorities around the country, Preston city council is not solely relying on the national test and trace system to help track the virus. It has taken matters into its own hands, setting up walk-in test sites and its own tracing system. Its team has received 300 local contacts a week, with council staff making home visits to more than 100 people who needed to self-isolate and could not be contacted by any other means.
