Errata: Vol. 57, Nos. 51 & 52

In the report, "Reduced Hospitalizations for Acute Myocardial Infarction After Implementation of a Smoke-Free Ordinance --- City of Pueblo, Colorado, 2002--2006," on page 1376, in the table, sex-specific rates were calculated using a denominator of total person-years for both sexes combined. The corrected table calculating sex-specific rates using a sex-specific denominator follows.
