The Centers for Disease Control and Prevention (CDC) is reporting an increase of measles in international travelers, resulting in at least 45 cases reported nationwide so far in 2024. Four cases have been reported in California, all of whom traveled overseas. CDPH recommends that healthcare providers suspect measles in patients with fevers, rash and any of the "3 Cs" (cough, coryza, or conjunctivitis) who have traveled internationally or interacted with international visitors in the last three weeks. In healthcare settings, to prevent spread if measles is suspected, isolate the patient immediately, in an airborne infection isolation room (AIIR) if possible, and promptly telephone the local public health department to report suspected cases. Ensure that patients are up to date on measles vaccinations before traveling abroad.
