AIDS in Los Angeles County

Beginning in January, the Centers for Disease Control in Atlanta expanded its definition of full-blown AIDS. It now includes the following additional clinical conditions: pulmonary tuberculosis, recurrent pneumonia, invasive cervical cancer and a count of fewer than 200 CD4+ T-cells per microliter of blood. This reporting revision accounts for the jump in reported monthly cases in Los Angeles County from a total of 344 in December to 1,609 in January. Because of this HIV-reporting change, the number of new cases will be significantly larger than before. Patient characteristics for L.A. County AIDS cases reported in January:
