If HIV is so weak that it cannot lead to immune system collapse then what is the cause of death among the HIV infected in south African blacks?
HIV cannot fully collapse your immune system, but it can come
close. Reason this is a problem is we need the function of our
immune system to fight off any disease even ones as simple as the
common cold or flu. If you have a weak immune system such as people
who have been diagnosed with AIDS (meaning a person cannot fight
off simple infections), then even the common cold becomes deadly.
So many south African blacks (or anyone) who are infected do not
die from HIV, but other diseases that they acquire because of their
weak immune systems.
