Rachel Wigglesworth, Director of Public Health for Cornwall and the Isles of Scilly, said: "We're asking anyone working in the hospitality industry to help themselves stay safe and protect their work colleagues by testing twice weekly using rapid lateral flow tests.
"While our case rate is still below the national average it has risen sharply. Now is the time to act to bring the rate back down.
"I would urge everyone to make twice-weekly testing part of their routine so we can identify cases even when people have no symptoms.
"Rapid Lateral Flow Tests are free of charge and can be picked up from your local pharmacy or ordered online".
