Estimates of First Recurrences, Hospitalizations, and In-Hospital Deaths Associated with CDI, According to Epidemiologic Class, at 10 U.S. Emerging Infections Program Sites, 2011–2017.^*

Surveillance Year	Estimated First Recurrences		Estimated Hospitalizations		Estimated In-Hospital Deaths
	Community-Associated CDI	Health Care-Associated CDI	Community-Associated CDI	Health Care-Associated CDI	Community-Associated CDI	Health Care-Associated CDI
2011	678	1959	1691	6145	159	889
2012	703	1848	2130	6527	161	571

2017	967	1221	2505	5483	164	573

^*The frequency of cases was weighted to account for sampling in two of the Emerging Infections Program sites (Colorado and Georgia) and sampling of health care–associated CDI cases. Recurrence refers to the first recurrent episode, defined as a positive stool specimen within 2 to 8 weeks after the initial positive test. Hospitalization includes admission on the day of or in the 6 calendar days after diagnosis of CDI. In-hospital deaths refer to deaths that occurred during hospitalization.
