Head Lice Now Drug Resistant

Drug-resistant head lice are very likely coming to a school near you, U.S. investigators warn.

At least 25 states host lice populations that don't respond to common over-the-counter treatments, a new analysis reveals.

Permethrin, part of the pyrethroid class of insecticides, has long been the go-to weapon against head lice, mosquitoes, bedbugs and other insects.

But continued exposure to permethrin has caused a huge swath of the dreaded insects to develop genetic mutations that render such drugs useless.

You can read the rest and learn which states are affected @



Going out on a limb, let's compare a map of states with drug-resistant lice (first map) to one showing which states have the highest percent of illegal immigrants in their populations (second map):

There really isn't a strong correlation, so I guess they're off the hook. Donald Trump, take note.
