I read the article and largely agree with aaron965 on this. There's a number of problems with saying "every responsible human being should be interested in knowing ...": 1) does knowing make you legally or criminally responsible for spreading the virus, as in the case of early AIDS patients? 2) Being exposed doesn't mean you'll get sick. So what to do next with the info you met somebody who is in the database? 3) In most Western countries, citizens can afford health care. However, in the USA and other developing nations, affording a hospital is not an option. So what's the point? The article presents an interesting idea, but separating policy and technology concerns when it comes to healthcare is really not a great idea. For now I think the traditional methods of dealing with seasonal flu make the most sense: offer information in the press and make affordable shots available.
