What??? That sounds really off-the-wall to me. I read the article but my first reaction is that maybe the reporter misheard something. I have never heard of the possibility of flu and HIV recombining.
I wonder if maybe what was actually being said was related to a possible scenario where regions with large numbers of HIV/AIDS patients, like Africa, could see very high mortality numbers because they are particularly susceptible to a novel flu bug. I'll have to wait for more press articles to confirm this statement.
