Those back-to-school selfies may spread super lice

Parents may want to add super lice remedies to the back-to-school shopping list.

A study in the Journal of Medical Entomology found that in North America, most head lice has evolved into a new, more powerful strain that is immune to traditional lice treatments, hence the name "super lice."

Canada is experiencing an alarming rise in cases, and there have been multiple outbreaks across the U.S. in recent years.

Because super lice can be difficult to get rid of, prevention is key. And that’s where those popular selfies come into play.

Any activity that brings kids' heads within close contact with one another, or involves sharing combs, hats, etc. will raise the risk of contracting lice. Dawn Mucci, founder of Lice Squad, told Global News that she is seeing a growing number of lice cases among teens, likely due to the selfie craze.

Parents should consult a medical professional on the most effective, safe treatments for super lice.
