"These people are being monitored and are being provided support where required."
Mr Sharp said GV Health will open a COVID-19 pop-up testing site at the Tatura Civic Hall (Victory Hall) at 75-81 Hogan St Tatura, on Friday, August 14 only.
The testing will be held from 10 am to 3 pm.
"No appointments are needed, noting this is for people who have symptoms of COVID-19," Mr Sharp said.
Mr Sharp said the hospital was undertaking contact tracing for all active cases in consultation with the Department of Health and Human Services, and were working as fast as they could to complete the process.
"Anyone identified as a close contact will be called directly by the tracing team," Mr Sharp said.
"Further details regarding any community locations of concern will be provided once this information is known and if it represents a concern."
Mr Sharp said a number of people had been tested for COVID-19, and reminded anyone who is a known close contact and has been tested to stay at home.
"(And) people should not present to the Acute Respiratory Clinic for COVID-19 testing unless they are contacted by a GV Health or DHHS," Mr Sharp said.
Mr Sharp said there were not any patients currently at GV Health with COVID-19.
