UPDATE: No new cases or recoveries; workplace outbreak remains

Tara Jeffrey No new cases of COVID-19 were reported for Sarnia-Lambton in the latest update from Lambton Public Health, published late Wednesday. The total number of infected remains at 327, with nine active cases currently. The number of resolved cases remains at 293. An active outbreak of COVID-19 declared this week at a Sarnia-Lambton workplace involves four cases, the health unit says, noting that workplaces will only be named if "public notification will help to identify additional close contacts that cannot be determined through contact tracing." Workplace outbreaks are declared when two or more employees test positive for COVID-19 within a reasonable timeline to suspect transmission in the workplace, the health unit states. "In this situation, Public Health will isolate cases, test and isolate those who have been exposed, and implement changes to reduce risk of transmission."

Cases are considered resolved when they are 14 days past symptom onset date, do not have a fever and COVID symptoms are improving or absent, according to the health unit.

Lambton Public Health follows up daily with cases and contacts throughout their 14-day isolation period.

Locally, a total of 19,635 tests results have been processed since the pandemic began, and 25 people have died.

Bluewater Health currently has no COVID-19 patients, and no one has been treated at the hospital or tested positive for the virus there since mid-June. As of Wednesday, 24 patients were in hospital with tests pending for COVID-19 (includes pre-surgical screening).

The City of Sarnia and the Town of Petrolia are the only two of 11 municipalities in Lambton that currently mandate masks.

Ontario recorded 95 new cases Wednesday.

Public health safety measures include staying home when sick, practicing physical distancing with others outside your social circle, use good hand hygiene, and wearing a mask if required or if physical distancing is not possible.
