Windsor-Essex has now hadmore than15,000 COVID-19 cases diagnosed since the pandemic began over a year ago.

The 57 new cases announced by the Windsor-Essex County Health Unit (WECHU) on Thursday brought the total to15,022.

Dr. Wajid Ahmed, the region's medical officer of health, said it's unfortunate that cases continue to rise but said vaccines are a "silver lining." He saidover 31 per cent of the local population has now received at least one shot.

"We are covering a large number of people,"he said,adding that vaccines alone aren't enough to stop the spread ofthe virus.

The health unit also reported one additional death, that of a woman in her 80s who died of COVID-19 complications after contracting the virus months ago. She was the 412th resident to die after contracting COVID-19.

Overall,478 COVID-19 cases are active in the region,141 of which involve the more contagious mutations of the virus known as variants of concern.

As of Thursday,144,405 vaccine doses have been administered and 130,897 people have gotten at least one dose.

Of the 57 new cases announced Thursday, 22 wereclose contacts of previously confirmed cases, 10 were community acquired, one wasoutbreak related, another was tied to travel outside North Americaand the remainder are under investigation.

Outbreaks are active across nine settings, including one new one at a school.

The outbreak at Amherstburg Public School, which like other schools has been closed since before the April break,involves two cases.

Ahmed said the outbreak was declared after a second case was discovered that had no known source and it was "reasonable to consider" that there could have been transmission.

The outbreak is contained and it should be cleared in the next few days, he said.

There are also eightoutbreaks at workplaces:

• Two in Leamington'sagriculturesector.
• One in Windsor's construction sector.
• Three in Windsor's health care and social assistancesector.
• One in Windsor's manufacturing sector.
• One in Tecumseh's manufacturing sector.
