🎯At a population level, maximizing ART uptake for
HIV has been shown to prevent the transmission of HIV and decrease the incidence of new HIV diagnoses

🎯This concept is referred to as “Treatment as Prevention” or “TasP”

🎯PLWH who have undetectable viral loads do not sexually transmit HIV

🎯This concept is known as “U=U” or “Undetectable = Untransmittable

🎯In only the first few months of operating, PATHS has demonstrated significant success in linking people to
HIV care and supporting them to achieve viral suppression, with over 75% of PATHS clients on HIV treatment, and nearly half of PATHS clients achieving viral suppression

📊There were 151 people referred to the MB HIV Program who have not been successfully linked to HIV
care

📊Only 66% of people referred to the MB HIV Program have a suppressed viral

🎯Innovative and meaningful efforts are needed to successfully engage & retain
people living with HIV in care

care

📈As of 2023, the incidence of HIV in Manitoba has risen to 26.4 HIV diagnoses/100,000 people - over five times higher than the incidence of HIV in Canada in 2022 (4.7 HIV diagnoses/100,000 people).
November 25, 2024 at 4:33 PM
