@drjoe_md: Impetigo is a highly contagious bacterial skin infection, often caused by *Staphylococcus aureus* or *Streptococcus pyogenes*. When it occurs on the chin after kissing someone with impetigo, it's likely that the bacteria were transmitted through close contact. The infection typically presents as red sores that quickly burst, leaving behind a yellowish crust. Treatment usually involves topical or oral antibiotics to clear the infection and prevent its spread. #impetigo #makingout #cellulitis #rash #doctor #skininfection #dermatology
