They say if you have not been contacted by the Health Department, and you (or your child) are not symptomatic, no action is needed at this time. The Health Department will contact you with instructions if you need to take action or will send information home with your child.

The outbreak has grown to the point that the Missoula County Health Department is immediately hiring nurses to assist in the outbreak.
