Diagnoses in men who have sex with men across New South Wales reduced from 295 cases in the year before PrEP roll-out to 221 cases in the year after—the lowest levels recorded since the beginning of HIV surveillance in 1985.
The study, led by the Kirby Institute at UNSW Sydney, followed 3,700 men who had been dispensed PrEP as part of the roll-out and found generally high levels of adherence.
Although a number of countries, including the USA, France, and England, have approved HIV PrEP, uptake has until recently been slow and geographically patchy.
“Our results support the population-level effectiveness of PrEP one year after rapid PrEP implementation at scale,” says Professor Andrew Grulich, from the Kirby Institute at UNSW Sydney.
“PrEP is a highly effective preventative approach when implemented alongside high levels of HIV testing and treatment.
