Ed Cerbone said seven other scouts showed symptoms of the H1N1 virus, but all 14 were expected to recover.
He said about a third of the boys were showing signs of recovery Sunday night.
Cerbone said the Troop 434 boys from All Saints Catholic Church got sick after a week at Camp Daniel Boone in North Carolina.
They were among about 700 campers who arrived June 7 at the camp near Asheville and were planning to spend a week at the camp. On June 8, several Scouts from a south Florida troop had temperatures in the low 100s, and were experiencing mild flu-like symptoms.
