About two weeks ago, one of my kids shouted out in the middle of a science experiment that a bug just jumped off of his head. I immediately sent him to the nurse, and my fears were confirmed- a bad case of head lice. After lunch the same day, another student said he was very itchy and his sister had lice. Once again, the nurse confirmed that he had a case of lice, too. My head itched the entire rest of the day!
The students have seen the nurse several times since their diagnosis, and have been cleared. I thought our outbreak of lice was over, until I got a report of another child with a case of lice, and my itchy has started all over again!
I never had lice as a child, and I don't remember any of my friends having it either. Mama said when she was in school, a note would be sent home with every child if a case of lice was spotted. In my four years teaching, I've never had such an outbreak before!

I decided to do a little research to find out what lice is and how it can be spread. According to kidshealth.org, lice isn't harmful and is more common in boys than girls. The louse actually feed on tiny amounts of blood that they suck from the child's head. When the kids are itchy, it is due to the reaction of the lice's saliva. Gross.
Louse lay eggs on the child's scalp. The eggs, called nits, attach to the hair shaft and take around two weeks to hatch. It is more common to spot the nits as the hair grows longer than it is to see the louse, as they are the size of a sesame seed.
Lice is very contagious. Lice cannot jump from head to head, but are spread through close contact in school, slumber parties, or sports. Sharing personal items like brushes and combs can contribute to their infestation.
Bottom line is that lice need to be spotted quickly so that treatment can be applied. Over the counter shampoos or prescription treatments can kill the lice. As teachers, we can help prevent the spread of lice by discouraging head to head contact and not letting children share personal items such as brushes, scarves, hats, or ponytail holders. We can also ensure the parents that lice are not a sign of being unclean and we can have the school nurse check their child's scalp regularly until the lice is gone.
And now my head is itching....more than ever. Guess I need to stop by the school nurse, too! :)
