U.S. citizens in China received their second alert in nearly two weeks warning of "unexplained health issues that have prompted the evacuation of a number of U.S. government employees working at a consulate in a southern city," the Associated Press reports.
Why it matters: The warning was sent amid American medical teams screening additional U.S. workers at the Guangzhou consulate, where a previous case prompted such tests. Per the AP, the alert told Americans to get medial help if they experience symptoms such as "dizziness, headaches, tinnitus, fatigue, cognitive issues, visual problems, ear complaints and hearing loss, and difficulty sleeping."
