The two contracted the dangerous Eastern equine encephalitis virus, called 'EEE."
According to Dr. Al DeMaria, the Massachusetts state director of communicable disease control, it is still unclear how the two became infected.
According to the federal Centers for Disease Control and Prevention (CDCP), there have only been a little under 200 confirmed cases of EEE in the U.S., since 1964.
The CDCP says, "symptoms range from mild flu-like illness to inflammation of the brain, coma and death. There is no licensed vaccine for humans."
