Riverdale has halted production after a person who works on the TV show came into contact with someone with coronavirus.
The programme, based on the characters of Archie Comics and starring KJ Apa and Lili Reinhart, was shooting its fourth season.
The person who has contracted the virus does not work on the hit show.
However, a spokesperson said the decision to suspend production was taken “out of an abundance of caution”.
Variety quotes a spokesperson for Warner Bros TV as saying: “We have been made aware that a team member from Riverdale, which is produced in Vancouver, was recently in contact with a person who has tested positive for COVID-19.

“The team member is currently receiving medical evaluation.
“We are working closely with the appropriate authorities and health agencies in Vancouver to identify and contact all individuals who may have come into direct contact with our team member.
“The health and safety of our employees, casts and crews is always our top priority. We have and will continue to take precautions to protect everyone who works on our productions around the world.”
The spokesperson confirmed: “Out of an abundance of caution, production on Riverdale is currently suspended.”
The coronavirus was first detected in the Chinese city of Wuhan at the end of last year, but it has now been reported in more than 100 countries.
So far there have been more than 118,000 cases globally and more than 4,000 people have died of the virus.
The outbreak was a factor in the new James Bond movie No Time To Die being delayed by several months and many music stars have postponed shows in recent days.
