Cold Grip (2005)

Robert, a businessman visiting Los Angeles, meets and has a one-night stand with Greta, an attractive but mysterious woman he meets at the airport. But Greta has a secret: she is an HIV-infected nymphomaniac whom targets and infects men for her own twisted enjoyment. When Robert learns that he may have contracted the fatal virus, his life changes for the worse when he decides to get revenge against Greta in the most horrific and hideous way to prevent her from infecting more men with HIV in the sense that he now has nothing to loose. But in so doing, Robert quickly becomes a murderous monster himself and he will kill again and again against anyone who stumbles upon his secret.
