Latin America Faces Tuberculosis Surge Fueled by Mass Incarceration
In Latin America, a big jump in the number of people in jail is causing more cases of tuberculosis (TB) – this change is undoing the progress made worldwide against the disease. Specialists say packed prisons are spreading the illness more, bringing terrible effects on the region’s public health.
The Prison-Tuberculosis Connection
High incarceration rates in Latin America have emerged as a key driver of tuberculosis, according to a recent study published in The Lancet Public Health. Between 2015 and 2022, while global TB incidence fell by 8.7%, cases in Latin America surged by 19%.
Researchers attribute this rise to the region’s rapidly expanding prison population, which has grown exponentially since 1990. In six countries—Brazil, Colombia, Mexico, Argentina, Peru, and El Salvador—prison populations skyrocketed from 260,363 in 1990 to 1,322,355 by 2019. These countries now account for nearly 80% of tuberculosis notifications in Latin America and more than 82% of its incarcerated population.
“Our main conclusion is that about a third of all tuberculosis cases in these countries since 1990 were associated with incarceration,” said Dr. Julio Croda of Brazil’s Oswaldo Cruz Foundation in an interview with The Guardian. He explained that TB rates among inmates are 26 times higher than in the general population due to overcrowding, poor ventilation, and inadequate healthcare services in prisons.
El Salvador represents the worst-case scenario. In 2019, 44% of its TB cases were linked to prisons, and the situation has worsened since President Nayib Bukele’s 2022 state of emergency, which dramatically increased incarceration rates.
Populist Crime Policies Driving Incarceration
Experts interviewed by The Guardian point to punitive crime policies as a key factor behind Latin America’s skyrocketing imprisonment rates. Harsh sentencing for low-level offenses, excessive pretrial detention, and a focus on punishment over rehabilitation have fueled the crisis.
Human Rights Watch’s deputy director for the Americas, Juan Pappier, told The Guardian that these policies have failed to reduce crime. “Instead of addressing the root causes of violence, mass incarceration has strengthened criminal organizations operating within prisons, such as Brazil’s PCC and Venezuela’s Tren de Aragua,” he said.
Sociologist Julita Lemgruber, who headed Rio de Janeiro’s prison system in the 1990s, explained to The Guardian how mass incarceration exacerbates public health risks. “People forget that in countries like Brazil, there is no death penalty. Inmates will eventually be released, potentially carrying tuberculosis acquired in prison back into their communities,” she said.
A Public Health Crisis in Latin American Prisons
Prisons in Latin America, as described by experts in The Guardian, are overcrowded, unsanitary, and poorly ventilated—ideal conditions for the spread of TB. Many inmates suffer from malnutrition, smoking-related illnesses, or substance abuse, further increasing their vulnerability.
Dr. Croda told The Guardian that TB cases in prisons are often underreported due to a lack of diagnostic tools and healthcare access. “Health services simply do not reach these populations,” he said.
The study analyzed by The Guardian projected that if incarceration rates had remained stable since 1990, the six countries would have seen 34,393 fewer TB cases in 2019 alone. A gradual 50% reduction in prisoner intake by 2034 could lower TB incidence by 10% in most countries.
Even halting Bukele’s state of emergency in El Salvador would not return TB levels to pre-2022 rates until 2034. Lemgruber told The Guardian that this underscores the urgency of addressing both the incarceration crisis and prison conditions.
Solutions for a Regional Health Emergency
Experts interviewed by The Guardian agree that decarceration is essential to curbing the TB crisis in Latin America. This includes reducing pretrial detention, implementing alternative sentencing for nonviolent offenders, and shortening prison terms.
Pappier told The Guardian that law enforcement should focus on dismantling organized crime networks rather than incarcerating low-level offenders. He said that overcrowding in prisons gets smaller while dealing with the main reasons for crime.
Dr. Croda told The Guardian about improving healthcare in prisons. He asked for TB checkups, which are often tools for finding diseases, and nicer treatment choices for prisoners. Prisons should become places that feel kinder and less shameful, he said.
Public health efforts might tell people about TB dangers and how to stop it, helping keep neighborhoods outside prisons safe. Lemgruber told The Guardian that addressing TB in prisons is not just a moral obligation but a critical public health measure. “This isn’t just about inmates. It’s about protecting society as a whole,” she said.
Latin America’s tuberculosis problem shows how health and law meet. As more people go to jail, the area needs to face the deep problems causing TB to spread in prisons.

With fewer people in jail, better prison living spaces, and more healthcare for everyone, Latin America has a chance to stop the scary increase in TB. Solving this problem will save lives and strengthen the region’s social and health systems for the years ahead.
