ICE health officials have been notified of 236 confirmed or probable cases of mumps among detainees in 51 facilities in the past 12 months, compared to no cases detected between January 2016 and February 2018. Last year, 423 detainees were determined to have influenza and 461 to have chicken pox. All three diseases are largely preventable by vaccine. -Reuters"When there is just one person who is sick, everybody pays," said 19-year-old Christian Mejia, who was put on lockdown in rural Louisiana's Pine Prairie immigration detention center along with hundreds of other detainees. According to internal emails reviewed by Reuters, outbreaks such as the one in Louisiana are difficult to manage, as immigrant detainees are often shuttled around the country, and many diseases don't necessarily show symptoms during the contagious phase.
