An unprecedented number of Americans have been incarcerated in the past generation. In addition, arrests are concentrated in low-income, predominantly nonwhite communities where people are more likely to be medically underserved. As a result, rates of physical and mental illnesses are far higher among prison and jail inmates than among the general public. We review the health profiles of the incarcerated; health care in correctional facilities; and incarceration’s repercussions for public health in the communities to which inmates return upon release. The review concludes with recommendations that public health and medical practitioners capitalize on the public health opportunities provided by correctional settings to reach medically underserved communities, while simultaneously advocating for fundamental system change to reduce unnecessary incarceration.

Several recent studies have shown that the racial disparities in U.S. mortality nearly disappear in prisons. We review the social determinants of the recent epidemic of incarceration, especially the war on drugs, and describe inmate morbidity and mortality within the context of U.S. health disparities. Incarceration provides an important public health opportunity to address health disparities by accessing a high-need, medically-underserved, largely non-White population, but it has also been associated with poor long-term health outcomes. Viewing incarceration within the context of community health and community life shows that the more equitable mortality rates among inmates are not evidence of the beneficial effects of incarceration so much as an indictment of disparities in the community at large. Because people of color are incarcerated far more frequently than Whites, the experience may ultimately exacerbate rather than mitigate health disparities.

Women often substantially overestimate their chances of getting breast cancer. Educational intervention by a physician, including explanation of an individual's calculated risk, can reduce this error. The effect of education appears to persist at least for several months.

M. pneumoniae caused a community-wide outbreak of cough illness and pneumonia and was associated with the development of life-threatening neurologic disease. Although M. pneumoniae was detected in schools, its transmission in households amplified the outbreak. Interrupting household transmission should be a priority during future outbreaks.
