A new strain of chicken pox (from some turd world country) is circulating.
Past infection and/or the innoculation for the Western strain should make this case very mild.
It's all over the country. (I live in Midland, TX and it's here, too.)
My son, who was vaccinated for chicken pox, had a pretty good case of them last month. It went around his school as well. The doctor said that they've been seeing more and more of this over the last few years. She didn't have an explanation why.
