Chicken pox (varicella zoster virus) is not kid stuff when it attacks adults. A mild childhood disease that most Americans get in school, adult-onset chicken pox can lead to painful shingles “ a herpes-related rash” and even death. Symptoms include the characteristic rash and red blisters, but may lead to swelling of the brain, called encephalitis, and pneumonia. It is spread through coughing and sneezing. In November 2006, four employees and four prisoners became infected at Florida's Manatee County Jail. The facility was promptly quarantined since the disease infects 70-80% of those who have not had it before. In July 2006, Florida's Pasco County Jail was also quarantined when one prisoner came down with the disease in a 56-man pod. Thirteen other prisoners were isolated because they had never previously had the disease. Thirty prisoners at the Mountainview Youth Correctional Facility in New Jersey were placed in quarantine in April 2007, after 27 tested positive for chicken pox. The quarantine was scheduled for up to 14 days. That same month almost 200 prisoners at a jail in Pima County, Arizona were quarantined after a chicken pox outbreak. While in quarantine they weren't allowed to attend religious services, self-help programs or court hearings, according to jail officials. At San Quentin State Prison, the Men's Advisory Council maintains a list of prisoners who previously had the disease, because the medical department “loses” its records of previously quarantine-exempt prisoners. This is necessary to prevent quarantine of the mainline prison population when chicken pox cases crop up several times a year due to non-medically cleared Reception Center prisoners being co-mingled with the general population.
