§ Numbers reported in each category may not add up to the total number of reported cases in a year due to cases with missing data or, in the case of race/ethnicity, cases categorized as “Other”.

¶ Health and Human Services Regions were categorized according to the grouping of states and US territories assigned under each of the ten Department of Health and Human Services regional offices (https://www.hhs.gov/about/agencies/iea/regional-offices/index.htmlexternal icon). For the purposes of this report, regions with US territories (Region 2 and Region 9) contain data from states only.

Source: CDC, National Center for Health Statistics, Multiple Cause of Death 1999–2017 on CDC WONDER Online Database. Data are from the 2013–2017 Multiple Cause of Death files and are based on information from all death certificates filed in the vital records offices of the fifty states and the District of Columbia through the Vital Statistics Cooperative Program. Deaths of nonresidents (e.g., nonresident aliens, nationals living abroad, residents of Puerto Rico, Guam, the Virgin Islands, and other territories of the US) and fetal deaths are excluded. Accessed at http://wonder.cdc.gov/mcd-icd10.html on August 23, 2019. CDC WONDER dataset documentation and technical methods can be accessed at https://wonder.cdc.gov/wonder/help/mcd.html#.

* Rates for race/ethnicity, sex, and the overall total are age-adjusted per 100,000 U.S. standard population in 2000 using the following age group distribution (in years): <1, 1–4, 5–14, 15–24, 25–34, 35–44, 45–54, 55–64, 65–74, 75–84, and 85+. Missing data are not included. Rates where death counts were less than 20 were not displayed due to the instability associated with those rates or where CDC WONDER did not have the functionality to calculate rates (e.g., for the “Other” race/ethnicity group). For age-adjusted death rates, the age-specific death rate is rounded to one decimal place before proceeding to the next step in the calculation of age-adjusted death rates for NCHS Multiple Cause of Death on CDC WONDER. This rounding step may affect the precision of rates calculated for small numbers of deaths.

† Cause of death is defined as one of the multiple causes of death and is based on the International Classification of Diseases, 10th Revision (ICD-10) codes B15 (hepatitis A).

Note: Numbers are slightly lower than previously reported for 2013–2016 due to NCHS standards which restrict displayed data to US residents.

* The number of estimated viral hepatitis cases was determined by multiplying the number of reported cases by a factor that adjusted for under-ascertainment and under-reporting (5). In this visual representation, the reported and estimated not reported add to the total estimated number of acute cases. The 95% bootstrap confidence intervals for the adjusted number of cases are shown in the Appendix.
