An investigation into the trends and patterns of infectious disease mortality rates in the US shows that while mortality rates have declined 18% overall, there is a disparity in the rates of decline between urban and rural counties. The study, published in JAMA, suggests as much as a 20-year spread in life expectancy between people living in different parts of the US, based not only on access to quality health care, but also societal factors such as poverty, crime, lack of stable housing, and food insecurity.
The infectious disease categories examined were diarrheal diseases, HIV/AIDS, meningitis, hepatitis, and tuberculosis. While lower respiratory infection had the largest absolute mortality inequality between counties, HIV/AIDS had the highest relative mortality inequality between counties. Diarrheal diseases were the only cause of infectious disease mortality to increase between 2000 and 2014. The counties with the highest mortality rates were located primarily in the southeast US.
