The shocking case of Amanda Berry, 27, Gina DeJesus, 27, and Michele Knight, 32, all of whom were abducted as long as 11 years ago, provides fresh hope for parents still grappling with their own child’s disappearance.

Thousands of people go missing in the United States each year and many are never heard from again.

According to the National Center for Missing and Exploited Children, roughly 800,000 children are reported missing each year in the United States — that’s roughly 2,000 per day.

It can cause pinkeye, a runny nose, loss of taste and smell, muscle aches, fatigue, diarrhea, loss of appetite, nausea and vomiting, whole-body rashes, and areas of swelling and redness in just a few spots.
