A Coles employee has tested positive to coronavirus, becoming the 20th confirmed case in Victoria.
The staff member had worked two shifts at the Waurn Ponds store in Geelong before being diagnosed after recently returning from the USA.
The young woman was a passenger on flight UA0600 from San Francisco and became unwell on her arrival on February 29.
The health department has labelled the store a public exposure site between hours of 8.45am-5pm on Friday March 6, and 1pm-6pm on Saturday, March 7.
A DHHS spokesman said the risk of transmission for customers was very low, however, shoppers who visited during those hours should inform a doctor if they start to feel unwell.
Coles issued a statement, saying the store immediately underwent an extensive clean in line with recommendations from the Department of Health. It will conduct further cleaning overnight as an additional precautionary measure.
