Body lice can often be controlled by frequent changes and washings of clothes. Lice problems are more common during the winter months compared to the summer and among people who wear the same clothes with minimal laundering and cleaning. Head lice, on the other hand, are not killed by frequent showers. When the infestation involves a school, health officials must be notified. All youngsters should be inspected for head lice and an educational program conducted so parents and teachers understand their responsibility in treatment of the entire population of students.
Monitoring needs to be continued until the problem has been eliminated.
Since lice survive for only a few hours off a human host there is no need to treat households with insecticides when inhabitants have a louse infestation. Treatments should be administered only to those individuals who actually have lice. Preventive treatments of non-infested persons is not warranted. John C. Nye, Dean and Director.
