A restaurant worker in the northern B.C. community of Vanderhoof has been diagnosed with tuberculosis, prompting the testing of dozens of other people.
The positive diagnosis was made last week, and the patient is now in isolation at home.
Public health nurses are still tracking down close contacts, including co-workers, friends and family. So far, 75 people have had TB skin tests.
Seven have tested positive, but medical health officer Dr. Lorna Medd said they don't have any signs of the illness.
Only further testing will determine if they actually have active TB, said Medd.
She hopes to have more information by Wednesday, after a specialist in Vancouver examines chest X-rays from Vanderhoof.
Active tuberculosis is infectious and can be spread by coughing or sneezing, but people with latent TB usually don't get sick at all, she said.
The person who is now in isolation handled food in a restaurant that health officials are refusing to name.
Dr. Medd did say the infectious person did not have contact with the public, noting that TB is an airborne disease that cannot be transmitted through food.
"We do not feel restaurant patrons are at any increased risk," she said, adding that patrons are not being tested.
