Mystery of Yemen cholera epidemic solved

The most likely source of the cholera epidemic in Yemen has been discovered by scientists. Through the use of genomic sequencing, scientists estimate the strain of cholera causing the current outbreak in Yemen -- the worst cholera outbreak in recorded history -- came from Eastern Africa and entered Yemen with the migration of people in and out of the region. Genomics can enable researchers to estimate the risk of future cholera outbreaks and help better target interventions.
