Exploring the latency period in Chagas disease: duration and determinants in a cohort from Colombia.

Background: Chagas disease has a varying latency period, the time between infection and onset of cardiac symptoms, due to multiple factors. This study seeks to identify and understand these factors to enhance our knowledge of the disease.

Methods: A retrospective follow-up study was conducted in Colombia on patients with indeterminate chronic Chagas disease.

Comparison of 1-year healthcare resource utilization and related costs for patients with heart failure in the Chagas and non-Chagas matched cohorts.

Background: Chagas disease is one of the leading causes of heart failure (HF) in Latin Americans, and there are limited data available that examine related costs of care for patients with HF. This study aimed to compare healthcare resource utilization and related costs for patients with HF, with and without Chagas disease.

Methods: A prospective matched-cohort study comparing the healthcare costs for patients with HF with Chagas disease and care costs for patients with HF without Chagas disease was conducted between January 2019 and December 2019.

Seroprevalence of SARS-CoV-2 Antibodies in Children and Adolescents: Results From a Population-Based Survey in 10 Colombian Cities.

Understanding COVID-19 dynamics in Colombia during the first pandemic year (2020) gives important insights surrounding population's exposure risk and specific susceptibilities. Seroprevalence studies can aid in having a broader understanding of the disease, offering a more inclusive view of the pandemic's impact across the population. A population-based cross-sectional study to assess antibodies against SARS-CoV-2 in 10 Colombian cities was developed between September and December 2020.

Comparison of methodologies for microscopic malaria diagnosis.

Introduction: As part of the pre-elimination plan for malaria in Colombia, it has been proposed to develop activities within the line of work: “Improve access and quality of malaria diagnosis”. Objective: To compare the methodology recommended by PAHO/WHO with that used in Colombia for the diagnosis of malaria. Materials and methods: Samples were collected and 88 slides were prepared for malaria diagnosis, under different scenarios according to the parameters to be evaluated.

Risk factors associated with Chagas disease in pregnant women in Santander, a highly endemic Colombian area.

Objective: To determine the prevalence and risk factors associated with Chagas disease in pregnant women in an endemic area of Santander, Colombia.

Methods: Cross-sectional study included 23 municipalities of Santander, Colombia. Serological IFAT and ELISA tests were undertaken to detect IgG anti- Trypanosoma cruzi.
