摘要：In this paper we have modelled the spread of HIV infections enhancing UNAIDS goal to end AIDS. The goal has two dependent missions.One side of the goal is a 90-90-90 target, that by 2020, (90% of all people living with HIV (PLHIV) should know their status, 90% of whose status is known should be under ART, and 90% of patients under ART should have their viral load suppressed. On the other side, by 2030; UNAIDS requires to minimize up to at least 90% of both new HIV infections and AIDS-related deaths. According to the model, the goal is linked to the basic reproduction number (R₀). When R₀ < 1 the number of new HIV infections decreases. Methodology: According to the model, we have demonstrated that HIV spread is controllable under some conditions in Botswana. For this country, R₀ ≈ 0:5051 which is below the threshold value R₀ = 0:6000. Thus, suggesting her potential to achieve UNAIDS goal. According to our evaluation from the model, by 2020, 92% of PLHIV are expected to be under ART. Interestingly, in Botswana new HIV infections are mostly due to people who are not under ART. By 2030 not only that 96% of PLHIV are expected to be under ART but also both new HIV infections and AIDS related deaths are expected to decrease above 90% since their highest in 2010. Our main concern is to provide more mathematical insights for UNAIDS to keep up with progress of the goal to end AIDS by 2030.
