Two more measles cases have been confirmed in Montana. One case in Hill County exposed others in the community.
Hill County public health officials announced late last week that a local child is isolating after they contracted measles.
In a press release, the health department said it was unclear where they became infected. It said the child also exposed an unknown number of people at a private gathering.
The county is holding an accelerated measles vaccine clinic to help prevent further spread.
Gallatin County officials also announced a ninth measles case. The health department is still investigating where that individual became infected. Previous cases were tied to out-of-state exposure.
Health officials are reminding the public the best way to avoid measles is by getting vaccinated. Two doses of an MMR vaccine prevents measles infections 97% of the time, according to federal health officials.
