Two rescued boys might have lung infection

The first four boys rescued from a Thai cave are aged 14-to-16, and two of them all show signs of a lung infection, a Thai health official says.

The boys will be staying in hospital at least seven days for further evaluation, including psychological evaluations.

The doctors said the rescued boys are in "high spirits'' and happy to be out of cave."

The four boys can now eat normal food but not anything that's spicy, a health official says..
