Uhm, a cold sore is herpes simplex.
Yup, strange little problem we have had for eons. Way back when people thought a cold sore was a sign of scurvy and upped intake of oranges, limes and lemons. Sty's about the eye also were a problem.
Sometime in the 60's these were considered a Staff or Strep infection, contagious like Pink eye.
Seems all these things mutate differently in every ones body to be passed on and the new body has the problem of having no antibodies to fight them and they then mutate again in another body.
People have only so long before the antibiotics no longer work on these problems. Much like the changing of the FLU vaccine every year for a new strain that has mutated from last years concoction.
The dilemma here is how much antibiotics is enough and how much is too much. This goes for all medication from Chemo to the combo drugs that we need. Too much and we begin to reject the drug, as many of us are allergic to penicillin. Even topical ointments soaps and cleaners can used too often cause harm.

Thalidomide a considered safe drug, a nightmare for parents and their children. When this broke upon the scene I had no children I was still a youngster, but the pictures in Life magazine were enough to when I did marry and become pregnant make me cautious of drugs.
Unfortunately I at 3-4 months pregnant developed an ear infection and the Doctor gave me Tetracycline and my first baby was born with little enamel on her future teeth, baby or adult.
Yes I am one to wash my hands 10 times a day and wipe down my counter tops in kitchen and bathroom with bleach and water. However I wonder when the nasty's we cannot see will not get so use to this they can mutate to become stronger and over come every thing from Clorox to hydrogen peroxide.
