Authorities in San Diego have reportedly found another case of the drug-resistant "superstrain" of the AIDS virus that was recently discovered in a New York man.  The new patient's "HIV has a similar molecular makeup as the patient in New York City," San Diego County Health Commissioner Nancy Bowen told the San Diego Union Tribune. The patient, whose name is not known, took a blind test last fall and tested positive. It's not known yet if the strain is an exact match, and authorities are trying to locate the person. If the second case is confirmed, it would weaken arguments that have been floated claiming the New York case is an anomaly, perhaps related to the patient's genetic makeup or his use of the drug crystal methamphetamine.
