Federal health investigators have confirmed that a Michigan infant has the West Nile virus and probably got it from the breast milk of his infected mother.
The child is healthy and his mother is recovering, the Centers for Disease Control and Prevention said. The CDC says it was virtually certain the virus came from breast milk, though there is no way to be completely sure.
Doctors stress that breast milk is the healthiest food for babies and that mothers shouldn't quit nursing because of West Nile gears.
The 40-year-old mother isn't being identified, but health officials do say she gave birth on Sept. 2 and received a blood transfusion that day and the next. She went home with her baby on Sept. 4, only to be hospitalized on Sept. 17 for three days.
Doctors later confirmed West Nile.
