A group of scientists from Mexico (Catholic population: >90%) have written a nice letter to Teh Pope in The Lancet Infectious Diseases. Its brilliant because its so simple and straightforward in its reasoning why Teh Pope should support condom use.
Lets pretend we live in a magical world, where everyone who is infected with HIV-1 has access to any and all antiretrovirals they need, at no cost. Scientists will still need to be working round the clock to develop new anti-HIV drugs, because HIV-1 can always figure out a way to be resistant to our drugs and highly fit.
Clinical data show that in some parts of Europe and the Americas one of every ten newly infected people has an HIV strain that is already resistant to one or more groups of antiretrovirals. Unfortunately, the list now includes primary infections in which multidrug-resistant HIV subtypes have been reported. The unavoidable conclusion is that sooner or later we will observe resistance to even the most efficient combinations of antiretrovirals, with all the clinical and epidemiological adverse consequences.
Know how we can shut this nightmare down? CONDOMS.
BONUS: Condoms are not a selective pressure on HIV-1. Viruses dont move on their own. They dont swim. Or fly. Or tap dance. They need semen/secretions to be transferred between partners. Know what stops that? CONDOMS.
The Vatican must understand that, in purely darwinian terms, HIV will never evolve resistance to condoms.
Preach abstinence. Insist your followers be faithful to their partners. Fine! But dont say stupid shit like this about condoms, Teh Pope!
Now that these scientists from one of the Catholicists countries in the world have made such reasonable, nonthreatening arguments for their case, Im sure Teh Pope will understand the implications of what he has done, and will be reversing his stance any second now.
