According to the statistics of Taiwan's Centers for Disease Control, as of 6 February 2014, there were 26,646 cases of Taiwanese becoming infected with HIV.
Another 893 foreigners have tested positive, most of whom have been deported by the Taiwan government before the policy change.
After careful study of harm-reduction programs in place in Hong Kong and Australia, a pilot program was started in four of Taiwan's 23 administrative areas in September, 2005.
This program has since been expanded nationally, and consists of 427 service sites for syringe exchange plus centres for methadone maintenance therapy.
Since 1984, incidence of infections through sexual contacts had accounted for 90% of all cases for most of time.
But in 2005, drug using patients accounted for more than 50%.
Taiwan's epidemic of HIV/AIDS began with the first case reported in December 1984.
Those who seek to avail themselves of such services can maintain their requirements online and browse the services on offer with ease.
Data from that year indicated HIV-1 rates of 0.09% for intravenous drug users, 0.2% for female sex workers, 1.9% for patients with sexually transmitted infections, and 6.7% for men who have sex with men in saunas or bath houses.
However, after the implementation of a harm-reduction program, a 10% decrease was seen in 2006.
On July 11, 2007, 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).
Until January 2015, the original HIV Infection Control and Patient Rights Protection Act required foreigners who tested positive to be deported, therefore most of the reported foreigners are no longer in Taiwan.
