impact The original 1990 AIDS Prevention and Control Act did not explicitly protect the right to work and had no penalties for refusing employment to HIV-positive people. Work discrimination in Taiwan became common, with even some state-run enterprises and government agencies requiring mandatory HIV blood tests. Examples of discrimination include the discharging of a Taipei police officer in 2001, the lay-ing off a healthcare worker in 2002, and a Taipei Metro driver who came under pressure and gave up his job. Infected foreigners and human rights Identification of HIV/AIDS-positive foreigners usually occurs during mandatory blood test for teachers, government agencies workers and some state-run enterprises employees. There are no penalties for enterprises refusing to hire a foreign person carrying HIV thus allowing work and employment discrimination. 1990 AIDS Prevention and Control Act In 1990, the government of Taiwan promulgated the AIDS Prevention and Control Act (後天免疫缺乏症候群防治條例). Under the AIDS Prevention and Control Act, foreigners who tested positive for HIV were required to be deported. The AIDS Prevention and Control Act was renamed the HIV Infection Control and Patient Rights Protection Act (人類免疫缺乏病毒傳染防治及感染者權益保障條例) on July 11, 2007, and will be referred to as such hereafter. The "original HIV Infection Control and Patient Rights Protection Act allowed the government to order HIV tests on foreign residents in Taiwan and short-term visitors staying in the country for three months or longer. Those whose tests came back positive were required to be deported." During the process of deportation, "their visas [were] annulled and their names [were] permanently listed in official records, resulting in automatic refusal of any future application for an entry visa." Foreigners infected by their Taiwanese spouse or from medical procedures conducted in Taiwan could appeal to be taken off of the black list, but only from abroad after being deported. The strict requirements for appeal were laid out in Article 20 of the HIV Infection Control and Patient Rights Protection Act. As summarized by the Taipei Times, "foreign nationals who were infected by spouses who are Taiwanese nationals, or who were infected while receiving medical care in Taiwan, and who have relatives within two degrees of kinship who have household registration and current residency in Taiwan may ask those relatives to prepare a written petition—only once—within six months of their deportation." Petitions appear to have been infrequently approved. Even in cases where both spouses tested positive for HIV/AIDS, petitions could fail
