Last summer, I noticed an odd spot on a leg of my female colleague when she arrived at work in a short skirt.

Fortunately, we are good friends and I could tell her without any kind of trouble.

Yes, she had a tick on that precise place a week before. Yes, it looked like erythema migrans, a typical early sign of a Lyme infection (borreliosis). No, she never heard about that and was a bit reluctant about doing anything about it. Yes, I persuaded her to see her doctor now. She got antibiotics immediately and seems to be fine.
