US health officials didn’t find signs of human-to-human bird flu spread after testing a group of people in Missouri with suspicious symptoms.

Five health-care workers with potential symptoms who were exposed to a bird flu patient didn’t show signs of infection with the H5N1 virus, Centers for Disease Control and Prevention officials said Thursday on a call with reporters. The patient, along with a household contact who also showed signs of possible infection, may have been exposed to the same infected animal, officials said.
