Erratum: Vol. 44, No. 28

For the article, "Pneumonia and Influenza Death Rates -- United States, 1979-1994," reexamination of the database detected an error in the age-adjustment procedure used to calculate the weekly mean pneumonia and influenza (P&I) death rates for noninfluenza periods. The following corrected paragraph replaces the first paragraph on page 536:

"To control for the highly variable seasonal contribution of influenza-associated deaths, the trend for mean weekly number of P&I deaths for the noninfluenza period (weeks 26-39) was analyzed. From 1979 through 1992, age-adjusted P&I death rates during these weeks increased from 3.1 to 3.7 per 1 million population. Analysis of P&I deaths listed in any position on the death certificate (multiple-cause-of-death data) indicated a similar increase."
