Lice Frenzy

Yesterday afternoon, the day care called and said "we have found head lice in some of the children at our facility. Misha was one of them." First I thought I heard "head light" and had to ask why Misha had anything to do with it, but OK, it is a parasite. I got that. They said they had info packet, and we would have to go through treatment.
After that this whole lice story grew in my head. A couple of students said they had had them when young, some colleagues told me experience at their children's schools or summer camps, and one colleague even called pharmacy for me to figure it out which med I need and what caution I should take ("you will be stripping off every bed sheets and pillows for washing!"). To make matters worse, on the way back to the day care, Temesgen said "we just shave hair off in Ethiopia." So in my head, there is a strange image of Misha with no hair... it just does not look right!
We got to the day care, and the director handed me an info packet and a zip log bag in which 'the louse" they found on Misha's head "imprisoned". So I look at it and realized I have never seen lice on humans (I saw on puppies before - Frontline clears very nicely). Then Temesgen looks at it and said "this is not a louse. This has wings!"
Of course, the day care cannot take in what parents say, which could be just a defensive comment. They said they required doctor's letter saying that Misha is free of lice. So we went to after-hour pediatric office, got confirmation from the pediatrician that she is free of lice, got the letter, etc.
So..... was it really lice on everyone's finding, or was it only Misha who was wrongfully accused? Was it a totally false alarm?
One person's "this might be..." becomes another person's "this must be." Then this becomes "this is..." creating frenzy out of nothing.
Oh well.... you will hear from me if I start scratching my head.
