Mumps in Gallatin County

Gallatin City-County Health Department is currently investigating two cases of mumps in Emily Dickinson Elementary and one case in Chief Joseph Middle School. Health department staff is working closely with Bozeman schools staff to identify students who are most susceptible of contracting mumps in order to take infection control measures to limit spread of the disease. It is important for parents to know that most students have significant protection against mumps through immunizations required by Montana state law and recommended by the U.S. Centers for Disease Control and Prevention. For more information please read the FAQ.
