Objective.

To estimate the prevalence of SARS-CoV-2 antibodies in an asymptomatic population in the state of Sergipe, Brazil.

Methods.

This cross-sectional study with stratified sampling (sex and age) included serological immunofluorescent
tests for IgM and IgG on samples from 3 046 asymptomatic individuals. Sample collection was performed in wet-markets of the 10 most populous cities of Sergipe, Brazil. Exclusion criteria included symptomatic individuals and health workers. The presence of comorbidities was registered.

In times of the COVID-19 pandemic, adequate, reliable and timely information becomes even more relevant. The Pan American Health Organization/World Health Organization office in Brazil and key partners have developed initiatives to improve access, sharing and dissemination of the information and knowledge produced, translated and systematized about COVID-19 as a technical contribution to the fight against the pandemic. This article presents some of these resources.

This report proposes a conceptual model on workplace environment and working conditions that integrates the available evidence to facilitate the design and evaluation of interventions aimed at improving the attraction, recruitment and retention of health personnel at the first level of care in rural and remote areas. Theoretical, empirical and testimonial evidence was consulted to support the model, and 15 frameworks disseminated in the last 20 years were synthesized.

Objective.

To describe the elements of the practice of certified nurse-midwives and women's health nurse practitioners in the context of the United States of America in order to facilitate the implementation of advanced practice nursing in Brazil.

Objective.

To determine if there are disparities associated with socioeconomic stratification, ethnicity, medical services, and geographic region in the progression of coronavirus disease (COVID-19) in Mexican adults
infected with SARS-CoV-2.

Objective.

Describe the clinical and epidemiological characteristics and resistance profile of cases of extensively drug-resistant tuberculosis (XDR-TB) diagnosed in Peru from 2013 to 2015.

Methods.

This descriptive study included patients who met the definition of XDR-TB and were reported to the national epidemiological surveillance system of Peru’s Ministry of Health. It used a descriptive analysis and, to identify spatial distribution, a heat map based on kernel density estimation.

Objective.

To describe the epidemiological, phenotypical and genetic characteristics of clinical isolates carrying the optrA gene identified in antimicrobial resistance surveillance by the laboratory of the National Institute of Health of Colombia.

Objectives.

To examine published antimicrobial stewardship (AMS) initiatives in hospitals in Latin America and the Caribbean (LAC) in order to characterize AMS terminology usage, geotemporality, and elements of structure (human resources), process (interventions), and outcomes, and to set priority areas for improving AMS reporting.

Objective.

To describe the genotypes of the carbapenemases reported from microbiological isolates of patients in Peru.

Objective.

To detect the presence of the ermB gene associated with macrolide resistance in Campylobacter spp. strains isolated from chickens marketed in Lima, Peru.
