Analysis of a Large Severe Acute Respiratory Syndrome Coronavirus 2 (Alpha) Outbreak in a Catalan Prison Using Conventional and Genomic Epidemiology.

Enforcing strict protocols that prevent transmission of airborne infections in prisons is challenging. We examine a large severe acute respiratory syndrome coronavirus 2 outbreak in a Catalan penitentiary center in February-April 2021, prior to vaccination deployment. The aim was to describe the evolution of the outbreak using classical and genomic epidemiology and the containment strategy applied.

Late diagnosis of HIV infection among prisoners.

HIV-risk populations are over-represented in prisons. It is very important to identify late HIV infection diagnosis in this setting from a public health perspective. The objectives of this study are to estimate the prevalence of late diagnosis and identify the predictive factors among inmates of two prisons in Barcelona from 2010 to 2012, and to review late diagnosis in other prisons.
