*

Any severity: infections that are mild, moderate, severe, life-threatening, or fatal.

High severity: infections that are severe, life-threatening, or fatal.

Site-specific bacterial infections were defined as evidence of bacterial infection by culture of a normally sterile site or by culture and evidence of tissue invasion of a nonsterile site.

§

Other includes skin and urinary tract, among other infections.
