At least 80 patients were infected at the No. 2 Hospital in Hubei province's Daye city, reports AFP
"We didn't know the blood was infected," Xu Chunyang, deputy director of the hospital told local media. He said the HIV contaminated blood came from a batch of blood-sellers who sold blood to the local blood bank a decade ago.
In the 1990s, selling blood was a popular way for peasants in central China to make money. Having little knowledge of AIDS, a number of blood-sellers were later discovered to have HIV, causing a huge AIDS scandal in the nation at the time.
The infection would not have recieved any attention if it was not because of Zhang Kai, a 38-year-old local peasant, who demanded compensation after he was tested positive for HIV last September.
Zhang was one of the patients who received a transfusion at the hospital from 1996 to 1997.
Victims passed the disease to their wives or children, bringing the total number of infected to around 100, according to the local paper Chongqing Evening Post.
