Influenza Surveillance
Dallas County Department of Health and Human Services, Communicable Disease Division, is once again helping the Texas Department of Health with influenza surveillance by sending throat swabs collected from four sentinel sites to the TDH lab on a weekly basis. The first positive culture was collected on 11-14-2000, with six additional positive cultures reported over the next three weeks. All have been identified as influenza A, type H1N1. In addition, two positive cultures of type A and another two type B have been reported by local hospital laboratories.
