Health officials investigating a cluster of mysterious illnesses in Alabama closed their investigation on Thursday after determining the illnesses were unrelated and were caused by the same viruses that cause flu.
The investigation involved 10 people who became sick and were admitted to hospitals in Dothan and Luverne in southeast Alabama.
Two died, six remained hospitalized Thursday, and two had been released, state Health Officer Don Williamson said. The 10 range in age from 24 to 87.
Williamson said health officials took extraordinary caution due to the emergence of two viruses, including the new H7NP, in other countries.
