We do know that Gimple will return as showrunner and that Robert Kirkman, Gale Anne Hurd, David Alpert, Greg Nicotero and Tom Luse will all executive produce Season 6. The Walking Dead clearly has a long-term trajectory in mind.
In this scenario, it would cost about $500 per DALY. At 20% coverage, targeted PrEP would cost $800 per HIV DALY averted. At both levels of coverage, non-targeted PrEP would cost about $1400 per DALY. This picture changes if the costs of ART for people who would otherwise be infected is also included.
Pre-exposure prophylaxis (or PrEP) is when people at very high risk for HIV take HIV medicines daily to lower their chances of getting infected. PrEP can stop HIV from taking hold and spreading throughout your body. It is highly effective for preventing HIV if used as prescribed, but it is much less effective when not taken consistently. Daily PrEP reduces the risk of getting HIV from sex by more than 90%. Among people who inject drugs, it reduces the risk by more than 70%.
