How is it not accurate?

(P1) People living in areas with a high concentrations of HIV+ people have a higher probability of contracting a disease than those who live in areas with low concentrations of HIV+ people.

(P2) People who do not practice safe sex face a greater risk of contracting a sexually transmitted disease than those who do practice safe sex.

(P3) Condoms, when used correctly, significantly lower the chance of contracting/spreading a sexually transmitted disease during intercourse.

(P4) Catholics living in Africa live in an area with a higher concentration of HIV+ people.

(P5) Catholics are prohibited from practicing safe sex/using condoms

(C) Therefore, Catholics living in areas with a high prevalence of HIV/AIDS, who are forbidden from using condoms, are far more likely to contract HIV/AIDS

[Petronski]

(P5) Catholics are prohibited from practicing safe sex/using condoms

False, at least twice. Not only in the matter of the prohibition, but also in the false assumption that use of a condom constitutes "safe sex."

[GCC Catholic]

You are missing your assumed proposition (P6) that African Catholics will not opt to abstain or be faithful any more than African pagans.

This proposition is false, thus your argument fails, in addition to the reasons given by Petronski.
