California health officials on Thursday confirmed 13 new measles cases connected to an outbreak at Disney theme parks last month, bringing the total number of illnesses to 39. The San Diego County cases include at least five people who showed up with fevers and rashes Wednesday at the Sharp-Rees-Steely Urgent Care Clinic in the suburb of La Mesa. The clinic was shut down for several hours and dozens of other patients at the clinic were questioned about their medical histories, officials said.
