Rock band Kiss have cancelled a gig after lead singer Paul Stanley tested positive for COVID-19.
They were supposed to perform in Burgettstown, Pennsylvania on Thursday.
Stanley, 69, has received both vaccines, as has “everyone on the entire tour, both band and crew”, Kiss said in a statement.
The band said they would release more information about future dates as soon as possible.
The statement said: “The band and their crew have operated in a bubble independently to safeguard everyone as much as possible at each show and in between shows.
“The tour also has a COVID safety protocol officer on staff full-time that is ensuring everyone is closely following all CDC guidelines.”
Stanley told fans he was “fine”, describing rumours about his condition as “absolute nonsense”.
“PEOPLE!!! I am fine! I am not in ICU! My heart allows me to do 26 miles a day on my bike! I don’t know where this came from but it’s absolute nonsense,” he wrote on Twitter.
The United States has seen a spike in COVID cases due to the Delta variant.
At the beginning of the summer, the virus appeared to be on the retreat but the daily average of new cases as of 25 August was 152,341, according to official figures.
Other musicians including Stevie Nicks, Garth Brooks and Nine Inch Nails have all axed performances for the rest of the year due to concerns over the variant.
