My DS has accepted his appointment and will (god willing) report on June 30. However, I'm a bit panicked right now because there is an outbreak of mono in DS's school, especially in the senior class. In fact, my DD (also a HS student) was tested for it (no results yet) and has symptoms. DS has no symptoms, but should I test him before I-day even if he remains asymptomatic? An active Mono virus can be asymptomatic for weeks or even months. If he has it, can he report at all? or be deferred? UGH! Why now??
