My teenage daughter's boyfriend has tested positive for mono. do i need to have her tested too? do antibiodics knock it out?

See below: Antibiotics do not help mono. It would not hurt to have her tested.

No/no: Mono often occurs in early childhood as a simple virus that is similar to most they have and seldom results in a doctor visit or diagnosis. They are then immune. It is more intense in teens or adults, but takes a good 3-6 weeks before most show signs. Antibiotics would not help anything (virus). Testing before any signs of illness is usually falsely negative. I'd just wait & see.
