...this makes me sick.
Until as recently as the mid-1990s, the Chinese government maintained that AIDS wasn't a domestic problem; foreigners were required to take HIV tests, while citizens were kept in the dark. In 1996, a doctor in Henan province discovered that, for nearly a decade, local officials had run a profitable but highly unsafe blood-selling operation that pooled blood from multiple "donors" (who were actually selling their blood) to skim the valuable plasma, then re-injected donors with the remaining blood cells. In some communities in Henan, as in many African communities devastated by AIDS, only grandparents and children are left behind. It is, arguably, the worst manmade public health crisis to occur here in recent history.
