In a blog post earlier Andrew Sullivan wrote that:
the US is the only developed country – and one of only a handful of undeveloped countries – that still tells the world that people with HIV are dangerous pariahs, who need policing at borders and deporting if discovered.
When I went to study abroad in Taiwan 2005-2006 they actually did require an HIV test to get a visa, as did China, who abandoned the policy with much fanfare a year or two ago. However, I never saw an announcement that Taiwan did so, but I also could not find any mention of it in the current visa application procedures. Does anyone know if Taiwan has abandoned the HIV test policy, and if so, when? I suspect that they ditched the policy around the same time China did, but did so quietly to avoid drawing any attention to the fact that they continued a system criticized as backwards and uncivilized when the PRC was doing it.
