Infectious diseases are mostly preventable but still pose a public health threat in the United States, where estimates of infectious diseases mortality are not available at the county level.


To estimate age-standardized mortality rates and trends by county from 1980 to 2014 from lower respiratory infections, diarrheal diseases, HIV/AIDS, meningitis, hepatitis, and tuberculosis.

Main Outcomes and Measures

Age-standardized mortality rates of lower respiratory infections, diarrheal diseases, HIV/AIDS, meningitis, hepatitis, and tuberculosis by county, year, and sex.


Between 1980 and 2014, there were 4,081,546 deaths due to infectious diseases recorded in the United States. In 2014, a total of 113,650 (95% uncertainty interval [UI], 108,764–117,942) deaths or a rate of 34.10 (95% UI, 32.63–35.38) deaths per 100,000 persons were due to infectious diseases in the United States compared to a total of 72,220 (95% UI, 69,887–74,712) deaths or a rate of 41.95 (95% UI, 40.52–43.42) deaths per 100,000 persons in 1980, an overall decrease of 18.73% (95% UI, 14.95%–23.33%). Lower respiratory infections were the leading cause of infectious diseases mortality in 2014, accounting for 26.87 (95% UI, 25.79–28.05) deaths per 100,000 persons (78.80% of total infectious diseases deaths). There were substantial differences among counties in death rates from all infectious diseases. Lower respiratory infection had the largest absolute mortality inequality among counties (difference between the 10th and 90th percentile of the distribution, 24.5 deaths per 100,000 persons). However, HIV/AIDS had the highest relative mortality inequality between counties (10.0 as the ratio of mortality rate in the 90th and 10th percentile of the distribution). Mortality from meningitis and tuberculosis decreased over the study period in all US counties. However, diarrheal diseases were the only cause of infectious diseases mortality to increase from 2000 to 2014, reaching a rate of 2.41 (95% UI, 0.86–2.67) deaths per 100,000 persons, with many counties of high mortality extending from Missouri to the northeastern region of the United States.

Conclusions and Relevance

Between 1980 and 2014, there were declines in mortality from most categories of infectious diseases, with large differences among US counties. However, over this time there was an increase in mortality for diarrheal diseases.
