infection risk

I am a science teacher.  While teaching of the circulatory system I allowed three children to ***** their fingers and put their blood on a slide and observe it under a microscope.  A parent suggested that I exposed their child to AIDS.  None of the 3 children have AIDS to their or my knowledge.  I used sterile single use diabetic lancets and the slides were never used nor the slide covers.  No child contacted the blood of another.  The wounds were washed and bandaged.  How valid is this accusation statistically?

Hi,

This does not have much ground or basis.

The needles you used were disposable, there was no blood contact.

You need to sit down and talk to the parents in detail and explain this to them.

They would understand this.

Hope this helps.

Good luck.
