During 1990-94, Chinese companies established thousands of plasma collection centers in poor rural areas of China to buy plasma and blood at from villagers. Government regulations at the time required testing collected blood for hepatitis B and C but not HIV. Not later than 1994, government officials became aware of problems — outbreaks of HIV in some collection villages and HIV-contaminated blood and blood products. Government from March 1995 closed all commercial plasma collection centers and required HIV testing. These response stopped the outbreak.
The first report I’ve found of this tragedy is a letter to Lancet in 1995 signed by a provincial official and a US academic. The letter reports a study supported by both the Anhui Province Health Department and the US National Institute of Health.
What followed appears to have been a back and forth struggle between government officials wanting to cover up or to expose the outbreak. From 2000, international newspapers and medical journals provided partial pictures of what had happened during the early 1990s, such as results from testing people in one or several villages.
There is, however, no clear picture of the extent of the disaster. How many blood and plasma sellers got HIV? Estimates range over a million. China’s Ministry of Health and UNAIDS estimated 55,000 former commercial plasma and blood donors were living with HIV in 2005. Even if this is an accurate account of the number alive in 2005, it is an incomplete count of the damage, because many donors infected during 1990-95 had died by 2005. From that report, the number infected would have been close to 100,000 — far greater than in the next largest recognized nosocomial outbreak in Romania, with an estimated 10,000 children infected during 1989-92.
