Should we ban HIV-positive immigrants?

Jonathan Rauch says no. He argues that allowing HIV-positive individuals to apply for residence will bring those individuals into mainstream medical institutions. The alternative may bring undocumented HIV-positive individuals who never receive good medical care or perhaps never even discover their HIV status, infecting others in the process. Rauch writes:

The ban on aliens with HIV was first imposed administratively, by the Public Health Service, in 1987, when fear of AIDS was at its peak and the disease was effectively untreatable. As therapies became available, public health authorities soon came to believe that the policy merely drove the disease underground and thus was ineffective, if not counterproductive. The first Bush administration and then the Clinton administration tried to revoke it. To no avail: In 1993, Congress wrote the HIV ban into law. No other disease faces such a statutory ban.

Even in 1993, the ban made little sense. America was the world's epicenter of AIDS, exporting rather than importing the disease, and so aliens were far more likely to get HIV in America than to bring it in. Anyway, the policy never required an HIV test for entry; only when an alien seeks permanent-resident status, usually after having already been in the country for years, is the blood test routinely required. So the policy, as put into practice, is about kicking people out, not keeping them out.

Congress was worried about the costs of welfare and publicly funded care for immigrants with AIDS. A valid concern, but one addressed by the underlying immigration law, which bars aliens deemed likely to become a "public charge," whatever their disease. Today, diabetics and cancer patients can visit and live in the United States on showing they have insurance or resources to keep themselves off the welfare rolls; only people with HIV are barred, whether they are sick or not. This is discrimination, pure and simple.

The numbers suggest that much is at stake: for instance about 1 in 12 Africans is HIV-positive, by some estimates. Singapore has faced related issues with foreign prostitutes.

Rauch's proposal, obviously is not a political winner, even though the Bush administration has been relatively sympathetic on the AIDS issue. I am interested in considering the deportation question more generally. Should we, for instance, deport SARS carriers? SARS is highly contagious to larger groups in a shorter period of time. Unlike HIV-positive status, you can't (it seems) just walk around with SARS for years. You might argue that if we deport SARS carriers, undocumented immigrants with SARS will be reluctant to report to hospitals. A good point, but I suspect that many of them rather quickly cannot continue on their own without dying. On the other hand, say you have an undocumented SARS patient on your hands. It is crazy to put them on a plane (we cannot over time afford many quarantined flights), best to leave them in a hospital. Nor does it gain you much to deport them once they are better.

So in looking for standards for deportable diseases, we might focus on rapidity of contagiousness, and ability to deport without infecting others in the process. Whether an individual can serve as a "silent carrier" can cut either way. On one hand, silent carriers can infect others for a longer period of time, which suggests a reason to boot them out (though of course they must go somewhere). On the other hand, it is the silent carriers that you want to report to the medical establishment. There is also a question of stock vs. flow. If the potential future flow of HIV-positives is high, that argues for deportation, as an incentive to keep others away. But if the stock is high relative to the flow, that argues for greater tolerance.

Sometimes it puts the world at risk to deport individuals before their treatment is complete, read this story on tuberculosis. And of course some of the deported will simply die without the medical care of the wealthier nation.
