A total of 24 staff are now self-isolating, Lancashire Live reports. The boozer would have reopened today after a deep cleaning.
The north-west England city boozer closed early on Friday, July 21 after the staff member completed a home test kit after becoming concerned about the local outbreak.
It is understood that the test was completed on July 27 and came back positive on July 30.
He is part of a group of Carlisle pubs where staff or punters have tested positive for the virus in recent weeks.
Two shifts, July 24 and 28, were identified as a matter of concern by authorities as the staff member had responsibilities through the pub on those dates.
Customer details have not been requested at this time, the channel said.
Wetherspoon spokesman Eddie Gershon said: “Wetherspoon has made the decision to temporarily close the pub.
“The local authority did not advise the company to close the pub.
“Local authorities and public health organizations have been very helpful and supportive.
“Details of testing and tracing customers have not yet been requested by authorities but are available when needed.
“Wetherspoon will reopen the pub as and when it can secure the number of staff needed to do so safely. “
Three other Cumbrian spots have been identified as having some of England’s highest infection rates, in the latest sliding seven-day data.
Covid-19 data for each local authority showed that during the seven days until July 28, Swindon, Melton, Eden in Cumbria had the highest rates, excluding northern towns with lockdown measures local in place.
And in July, Cumbria County Council called on punters who frequented three Carlisle pubs on certain dates to take a test.
Ad-goers were encouraged to get tested even if they didn’t show symptoms after six people tested positive.
The call for contact tracers follows a “slight but worrying increase” in the number of Covid-19 infections early last month.
Drinkers who visited Lloyds Bar on Saturday July 11, The Museum on Monday July 13 or The Turf on July 9, 10 or 13 were also asked to get tested as a precaution.
