VANCOUVER -- Nearly two dozen more COVID-19 exposure notices have been posted at B.C. grocery stores and pharmacies in the past week.

Loblaws, Sobeys and T&T Supermarkets have all posted warnings of possible exposures to the disease since last Monday. 

While the risk of transmission tends to be low in these cases, the companies say they post these notices in an effort to remain transparent. None of the notices prompted warnings from the stores' respective health authorities.

Some other companies have chosen not to post their exposure notices online. Last month, London Drugs said in an emailed statement to CTV News Vancouver that its communication is "a direct result of recommendations and guidance from the local health authority."

Save On Foods also told CTV it doesn't post exposure notices online unless directed to do so.

Loblaws, Sobeys and T&T all keep their exposure notices online for two weeks.
