The Windsor-Essex County Health Unit announced a four-day total of 304 new COVID-19 cases on Tuesday.
The public health unit said 100 of those cases were reported on Saturday, 83 were reported Sunday, 50 were reported Monday, and 71 were reported Tuesday.
Overall, 616 cases are currently active, including 347 linked to COVID-19 variants of concern. The numbers come as new COVID-19 measures targeting workplaces as well as bars and restaurants take effect. Later this month, new restrictions will be in place for weddings as well.
"We are in a very difficult situation right now," Dr. Wajid Ahmed, medical officer of health, said on CBC Radio's Windsor Morning on Tuesday.
"Case counts are increasing in our community and also across the province and it is absolutely important for us to take all of that risk into consideration as we head into fall. The schools are opening today and we have to bring it down," he said.
Meanwhile, the region surpassed a milestone in its COVID-19 vaccination effort. As of Tuesday, the percentage of eligible residents who have had one or more COVID-19 vaccines has risen just past 80 per cent. The vaccination rate remains below the provincial figure, however, which stands at 84 per cent.
Ahmed said that vaccinations are up following the provincial vaccine certificate announcement, as well as mandates at some institutions.
