SF Health News Examiner: Officials fear swine flu combined with HIV

"As the global threat from the most recent outbreak of H1N1 'swine' flu seems to have peaked, health officials remain concerned that the virus might return this fall in a far more deadly form.

So warned Dr. Margaret Chan, head of the 193-nation World Health Organization, in a recent interview with the Financial Times of London. In the interview, Dr. Chan claims that the H1N1 swine flu virus that caused the Mexico City-centered outbreak could return in the fall in a mutated form that is far more dangerous than the present version."
