So your position is that the entire country (world maybe) should have access to identity information for everyone who currently has a potentially fatal, communicable disease? Knowing their email addresses would hardly be adequate to help people avoid the problems you describe, so you must (logically) be advocating for revealing actual names and work/home addresses.
Hmmm - so what other diseases should be accorded such special status?
Unless you have some kind of unseemly bias, you must be concerned about all diseases that are at least as communicable as HIV, and which cause at least that number of deaths - would that be a reasonable low bar for you?
So...let's see - in the UK, about 6,000 people die every year from HIV/AIDS - and about 25,000 die from influenza.
Oh [citation required] huh? OK - the numbers are here:

http://www.theguardian.com/soc... (28,000 people died from influenza in just two weeks in January 2015)
How about communicability?
To be infected by HIV, you need to exchange body fluids - pretty unlikely to happen, statistically.
To be infected by influenza, you just need to be standing nearby when they sneeze - incredibly likely.
So - unless your position comes from a specific bias against HIV sufferers *because* of the most common routes of infection - you should reasonably be pressing the government to release the names of all known influenza sufferers instead.
I think we know what your feelings are in that regard - so we can only conclude from your post that it's pure, unreasoning bias.
