The Virology Section is located inside the main State Public Health Laboratory building at 250 N. 17th Avenue in Phoenix. This section's responsibilities include the isolation and identification of viral agents from clinical specimens, the testing of reference specimens submitted as viral isolates from public and private laboratories for identification purposes, the testing of environmental samples for arbovirus isolation and identification, and the testing of animals for rabies.

In addition, the Virology Section acts as a transfer agent for the Centers for Disease Control and Prevention (CDC), accepting specimens or isolates from public and private health facilities for submission to the CDC.
