Barbara Walters, the 83-year-old veteran news anchor and co-host of "The View," is in the hospital with chicken pox, according to news reports…Stacey Rizza, who is the chair of the HIV clinic at Mayo Clinic, an infectious disease expert and associate professor of medicine at the Mayo Clinic, told HuffPost that getting chicken pox as an adult can lead to more severe symptoms because "your immune system is not as young and ready to attack, so you get a little sicker."
