Windsor-Essex Faces Rising Sexually Transmitted Infections Crisis

Health authorities in Windsor-Essex are raising alarms over a significant increase in sexually transmitted and blood-borne infections (STBBIs) in the region. The Windsor-Essex County Health Unit (WECHU) reported a total of 1,464 STBBI cases in 2024, marking a 15 percent rise from previous years. As of September 19, 2025, 853 cases have already been documented, indicating a concerning trend that health officials are closely monitoring.

Dr. Medhi Aloosh, the Medical Officer of Health for WECHU, attributes some of this rise to changes in sexual behavior among residents. “We see more syphilis among heterosexual individuals and women, leading to congenital cases of syphilis. This reflects shifting behaviors and increased risk,” he stated. The health unit’s report highlights a growing prevalence of chlamydia and gonorrhea, which remain the most frequently reported STBBIs.

Syphilis and hepatitis C also rank among the top ten infectious diseases of public health significance in Windsor-Essex for 2025. Common risk factors for these infections include unprotected sex, multiple or anonymous sexual partners, and substance use. Dr. Aloosh emphasized the importance of awareness, stating, “Anyone can contract a sexually transmitted disease. It is crucial for everyone to understand that this can affect any age group—young, old, or wealthy.”

The report indicates that individuals aged 20-44 represent the highest incidence group for chlamydia and gonorrhea. “The surge in anonymous sex, often facilitated by apps, has led to higher risks associated with multiple partners,” Dr. Aloosh explained.

Under the Health Protection and Promotion Act, health units like WECHU are mandated to monitor and report diseases of public health significance, which includes STBBIs such as chlamydia, gonorrhea, syphilis, HIV, and hepatitis B and C. The health unit noted that certain populations in Windsor-Essex are disproportionately affected by these infections due to intersecting social, behavioral, and structural vulnerabilities.

As health officials continue to address this public health challenge, they urge community members to engage in safer sexual practices and prioritize regular health screenings. The rising rates of STBBIs underscore the need for increased education and awareness initiatives aimed at reducing transmission and improving overall public health in the region.
