Who We Are
 



The Upper Missouri District Health Unit (UMDHU) was founded and began offering sanitation and nursing services in Divide, McKenzie and Williams Counties in 1947. It was the third public health unit formed in the state. Mountrail County joined the health unit in 1949. The central office is located in Williston; satellite offices are maintained in Crosby, Stanley and Watford City (all are county seats).

Cyclospora
Cyclospora is a parasite that is so small it can only be seen under a microscope. When people eat food or drink water that’s contaminated with Cyclospora, they can get an intestinal illness called cyclosporiasis. To date, Cyclospora is believed to only infect humans and spread through human fecal matter. Cyclospora is generally transmitted when infected feces (poop) contaminates food or water. It’s unlikely to be transmitted directly from person to person because the Cyclospora parasite needs time (days to weeks) after being passed in feces to become infectious.
