Introduction: In a correctional facility, a chickenpox outbreak poses a risk to community health. Overcrowding facilitates the rapid spread of infectious diseases, making it crucial to implement timely measures to prevent and control its spread. This study aimed to investigate a chickenpox outbreak among inmates in Pereira, Risaralda on November 19, 2022.
Methodology: A descriptive study of outbreak response was conducted according to the methodology of the Pan American Health Organization. The source of information was the Public Health Surveillance System (Sivigila). Absolute and relative frequencies, attack rates, and proportions were calculated for univariate descriptive analysis.
Results: Four cases (three inmates and one guard) were identified, with an average age of 28 years, ranging from 19 to 39 years. The overall attack rate was 0.4%, the attack rate in courtyard three was 1.4%, and for the guards, the attack rate was 0.8%. As a strategy for monkeypox monitoring, RT-PCR, IgM, and IgG samples for chickenpox were taken, all of which tested negative.
Conclusions: A chickenpox outbreak with four cases was confirmed, with a propagated source. The onset of symptoms began on July 11, 2022, with the last detected case showing symptoms on August 5, 2022. The overall attack rate was 0.4% (4/970). Follow-up concluded on August 16, 2022, after two incubation periods of the chickenpox virus (42 days). No deaths or hospitalizations were reported.
