Kenya has confirmed a ninth Ebola case, prompting concern about possible regional spread. The latest patient is a 24-year-old man who was already being held in quarantine. He tested positive while under official observation. His diagnosis brings Kenya's recorded caseload to nine. The announcement gave no quarantine location, symptom details or explanation of how he was exposed. Health officials must now establish whether he is linked to earlier patients and trace his close contacts for possible infection.
