Sore throat after working with Streptococci strain Okay so I’m taking microbiology in uninversity and during our lab two nights ago we were working with a few strains of Staphylococci and Streptococci (Specifically Strep aureus, and Strep pyogenes). 

This morning I woke up with a crazy sore throat but no other symptoms at all. Is there a chance that I could have infected myself? Also, I kissed my boyfriend last night and I’m worried I will pass it to him, how can he prevent that?
