Should you throw away lip gloss after having strep?

Yes, definitely. Although most say the strep bacteria will not harm you again from that particular strain if you took antibiotics etc, my letting it live in your lipgloss it grows and can mutate. you also put others around you at risk because they are not immune to the virus. If you have a boyfriend or girlfriend you could pass it to them as well from your lipgloss. Toss it. wait a few days and get a new one.
