Mumps in Migrant Detention Centers

JAMA. 2019;322(14):1344. doi:10.1001/jama.2019.15663

Nearly 900 confirmed and probable cases of mumps have been identified in US migrant detention centers in the past year, according to a recent CDC investigation.

According to the investigators, a total of 898 confirmed and probable mumps cases were reported in adult migrants at 57 detention facilities in 19 states between September 1, 2018, and August 22, 2019. Most cases occurred in men (94%). Of the 527 infected men reporting complications, 15% experienced swelling of the testes. Given the 12- to 25-day incubation period prior to symptom onset, the investigators concluded that 84% were exposed while in US custody, 5% were exposed prior to being taken into custody, while the time of exposure for 11% was unknown. There were ongoing outbreaks at 15 US detention facilities in 7 states as of August 22, 2019, according to the authors. Frequent transfers of migrants between detention facilities may be contributing to the ongoing spread, the authors note.
