I wrote a lot about West Nile Virus in Worry Proof, mostly because parents often don't want to hear the benefits of DEET. Well, it's back. with a vengeance. And with all of the talk about climate change and temperatures that will slowly creep up over our lifetimes, it's pretty safe to assume that the mosquito population will creep up, too. With the dramatic reappearance of West Nile this year, don't forget to put on long sleeves, long pants, and insect repellant when necessary.
