...been followed over decades, the roughly 1,200 carriers of the trait, all of whom were African-American, were 40% more likely after adjustments to be infected with HIV than noncarriers. From that sample, Weiss and his colleagues extrapolated the infection risk attributable to the gene variant in Africa, where a 40% increased susceptibility to infection translates to about 11% of all infections...
There's no doubt Africans have borne the brunt of the AIDS epidemic. Now researchers in London and Texas say it may have something to do with a single gene variant that could account for 11%, or about 2.5 million, of Africa's HIV cases...
...gene variant lived on average two years longer than noncarriers. "We still can't say exactly why," Weiss says. And though the effect of this gene variant, if confirmed, could help explain a huge number of HIV infections, it still cannot come close to explaining the AIDS burden of Africa. Nearly 70% of all HIV-positive people in the world live in sub-Saharan Africa, and prevalence rates in adults in some African countries top 20%. What's more, the gene variant is most common in West Africa, but HIV-infection rates in that region remain very low compared...
...shambles today and its economy a well-documented ruin after years of prosperity. The West, however, said nothing about this theft of land, fearing that it would be "politically incorrect" to criticize racially motivated land reform. For too long Mugabe has piggybacked on the sentiments of those sympathetic to Africa's liberation struggle; he is in a sense the creation of Western liberals. Charles Wukasch, Austin, Texas...
