A 5-year-old boy who just returned from West Africa was transported to Bellevue Hospital Sunday with possible Ebola symptoms, according to law-enforcement sources.

The child was vomiting and had a 103-degree fever when he was carried from his Bronx home by EMS workers wearing hazmat suits, neighbors said. “He looked weak,” said a neighbor.

“He was really, really out of it.”

The boy returned with his family from Guinea Saturday night and five members of the family were being quarantined inside their apartment, sources said.
