SAN DIEGO (AP) – Last week’s announcement that a San Diego resident tested positive for a possibly aggressive and drug-resistant strain of HIV turned out to be inaccurate, local health officials said Feb. 18.

The test results did not come from San Diego, as investigators reported Feb. 14, according to the San Diego County Health and Human Services Agency. The agency does not know where the test results originated.

The results gained attention after a New York City man was found to have an unusually drug-resistant strain of HIV. San Diego County health officials had said a records search indicated an apparently similar strain was found last fall in an unidentified San Diego resident, prompting a search for the patient.

Dr. Nancy Bowen, the county’s public health officer, said Feb. 18 officials at a commercial laboratory in the San Francisco area “are certain that this test was not from a San Diego-area patient.”

For privacy reasons, the laboratory did not tell county officials where the test was made, agency spokesperson Leslie Ridgeway said. She declined to identify the laboratory.

Health officials in New York have worked to track the unusual strain of HIV, which progressed to full-blown AIDS less than three months after the patient was diagnosed with the virus.

The New York City Department of Health and Mental Hygiene has said the patient, a man in his mid-40s, had many sex partners in recent weeks while using the drug crystal methamphetamine.
