Teenage girls often get Mono from sharing sodas with their friends. From what I understand, it is usually spread through saliva. I can't imagine a teacher that would spread vicious gossip like that about a teenage girl. Its awful.
The teacher probably just didn't like the girl, maybe for good reason, maybe not. Teachers are supposed to set a good example for their students by acting like adults, but they're capable of pettiness, too. A similar thing happened to me when I was in school. I didn't get along with one of my teachers, and she bad-mouthed me to other students.
Not just girls, guys too.
A bunch of my friends got it all at once, in the stupidest way possible.
One idiot (we'll never know which one) drank out of the gatorade bottle (the ole 64 ouncers) and a few of the guys poured it into cups.
Wound up with a bunch of guys all getting it.
Though I had bought the gatorade in the first place for them, I had my own and lucked out.
This teacher is not just ignorant, but vicious, and needs to be both fired and sued.
I've heard it called "The Kissing Disease" before. Never have I heard someone say that it's "The Whores Disease". LOL!
I only know of one person to have ever gotten mono, she was in my senior class. And trust me, no one was sleeping with her LOL!
