Dr Alex Garza is the SSM Health Chief Community Health Officer and Incident Commander for the St. Louis Metropolitan Pandemic Task Force. He joins Megan Lynch following up on a story last week that showed a small number of doctors who have actually diagnosed measles. 'It's very unusual for a clinician' to actually diagnose measles, says Garza. He explains the procedures and protocols that medical facilities have in place, but mentions a 'heightened awareness' for measles right now.
