This outbreak sired 18 regionally acquired instances, together with one which resulted within the younger Miami girl’s demise. To find out the supply of the an infection, docs reviewed the lady’s journey historical past and carried out genetic sequencing of the virus, which confirmed that it was regionally acquired.
