Native Americans are hardest hit by syphilis surge

From her base in Gallup, New Mexico, Melissa Wyaco supervises about two dozen public health nurses who crisscross the sprawling Navajo Nation searching for patients who have tested positive for or been exposed to a disease once nearly eradicated in the U.S.: syphilis.

Infection rates in this region of the Southwest — the 27,000-square-mile reservation encompasses parts of Arizona, New Mexico, and Utah — are among the nation's highest. And they're far worse than anything Wyaco, who is from Zuni Pueblo (about 40 miles south of Gallup) and is the nurse consultant for the Navajo Area Indian Health Service, has seen in her 30-year nursing career.
