Jacien: Yeah, these are the countries that will benefit most from this discovery, if it holds as viable. It should definitely be pursued and explored with all due haste for this reason alone.
Saint: Yeah, that's about what it is. There are several standard antiretroviral drug cocktails which can be administered to combat HIV and it's becoming very clear that the sooner they are administered after infection, the less likely the virus will be able to gain a sufficient foothold for AIDS to manifest.
However, these drug cocktails have only really been tested on adults, and even then there are some side effects. However, they're temporary and well worth it to stop an HIV infection. I don't believe their effect on infants is known, especially if the infant is having to continually take them for a period of time.
