Health officials around the world are mobilizing against the H1N1 virus, commonly known as swine flu, but Indian Country has largely been spared from cases.

The Tohono O'odham Nation of Arizona reported four cases -- all children. The tribe's reservation spans the border with Mexico, where the current outbreak originated.

The Mille Lacs Band of Ojibwe of Minnesota and the Lac du Flambeau Band of Lake Superior Chippewa Indians of Wisconsin took steps to address the virus after suspected cases were reported on their reservations. The Havasupai Tribe of Arizona hasn't been affected all but has delayed the reopening of its Grand Canyon campground due to health concerns.

But the Indian Health Service is prepared to take action if necessary. "We activated our emergency coordination center early on, and all of the tribes have put their emergency response plans into action. We feel the response has gone very well," Dr. John Redd, branch chief of the IHS Division of Epidemiology, told Indian Country Today.
