Question

Quizplus · Accepted Answer

The most likely reason that some lice can survive treatment with permethrin while others cannot is a genetic variation in the louse population that allows some lice to be resistant to permethrin. This is a common phenomenon with many anti-parasitic treatments, and it underscores the importance of monitoring the development of resistance in parasite populations.
