Symptoms? What Is going on?? ? PLEASE HELP!!!!!!?

I am 14, and recently everyone at my school has been getting sick. I went to a place called Jumpity Jump with moonbounces yesterday evening with my friend and her church group. And she said she could feel boogers in her throat. Now this morning I feel like I have boogers in my throat, and A sore throat, and a really bad headache but no fever. What's wrong with me? Thanks in advance!
