A Vulnerable Population* Regarding health needs, prisoners represent one particularly vulnerable and forgotten population. While the prison system in Zambia had an official capacity of 8,250 as of 2017, in 2019 it housed over 22,800, many of whom have never been convicted or are awaiting trial. Overcrowding, malnutrition, infectious diseases including TB and HIV, scarce medical care, violence, and inadequate hygiene facilities are just a few of the challenges facing men, women, and children in these prisons every day. Of note, infectious diseases, including COVID-19, are known to spread particularly quickly in confined prison settings around the world.
