Event Description

The Windsor-Essex County Health Unit’s surveillance and monitoring system has identified an increase in opioid-related Emergency Department (ED) visits and Emergency Medical Service (EMS) calls inclusively between September 14th and September 20th of 2021.

Over this consecutive seven-day period, it has been identified that there were 12 fentanyl overdoses, nine (9) of which were reported by Windsor Regional Hospital and three (3) of which were reported by Erie Shores Healthcare. Historically, the number of overdoses reported during this period are significantly high when compared to our 5-year average for Week 37.

Based on the information available, a public alert is warranted.
