⁺Infant ID deaths were restricted to singleton infants born in the United States to U.S. residents with an infectious disease underlying cause of death on the death record. Infant: <1 year old. The number of deaths is weighted to adjust for unlinked death records and is estimated using weights provided by the National Center for Health Statistics.^12–15 The percent is calculated among all infant ID deaths.

^*LBW: Low Birth Weight (<2500 g), NBW: Normal Birth Weight (≥2500 g). LBW and NBW deaths may not add up to overall deaths because of rounding due to weights.
