Update, 2:45 p.m. Wednesday: U.S. Customs and Border Protection (CBP) is temporarily suspending intake at the McAllen Central Processing Center, the largest migrant processing center in South Texas, after the outbreak of what the agency calls "a flu-related illness."
It is the same facility where a 16-year-old Guatemalan boy became ill last week, and died after he was transferred to another Border Patrol station.
According to a CBP spokesman, after identifying 32 individuals who tested positive for influenza, all were provided treatment on the site or in local hospitals "as appropriate." As of Wednesday afternoon, the Central Processing Center resumed operations.
CBP officials say Carlos Hernandez Vazquez was found unresponsive on Monday morning. A nurse practitioner had diagnosed him with influenza A, and he had been moved between facilities to separate him from other migrants to stop the spread of the flu.
