Staphylococcus aureus infection disparities among Hispanics and non-Hispanics in Yuma, Arizona.

Staphylococcus aureus infection patterns in Yuma, Arizona show a 2.25x higher infection rate in non-Hispanics. Males had higher infection rates in most age classes. These disparities in infection are mostly consistent with previously observed patterns in colonization, suggesting that sex and ethnicity do not differentially impact colonization and infection.
