Lockdown as an Intervention Measure to Mitigate the Spread of COVID-19: a modeling study.

Introduction: This work aims to develop a biomathematical transmission model of COVID-19, in the State of Sergipe, Brazil, to estimate the distribution of cases over time and project the impact on the spread of the epidemic outbreak due to interventions and control measures over the local population.

Methods: This is an epidemiological mathematical modeling study conducted to analyze the dynamics of the accumulated cases of COVID-19, which used a logistic growth model that adds a term of withdrawal of individuals as a control measure. Three possible COVID-19 propagation scenarios were simulated based on three different rates of withdrawal of individuals.

Preservation of forensic traces by health professionals in a hospital in Northeast Brazil.

Background: Health professionals who work in emergency services must be prepared for the recognition, collection, storage, preservation and documentation of all physical traces related to injuries or crime, because failures in these processes may compromise any forensic analysis. We, therefore, investigated emergency health professionals' levels of knowledge about these processes and their abilities to implement them in practice during the care of victims of violence in an emergency unit of a specialized trauma hospital.

Methods: This was a survey to describe the knowledge of professionals working in the emergency department of the Sergipe Urgent Care Hospital (HUSE) in Sergipe state, Northeast Brazil about the preservation of forensic traces and their ability to implement the necessary related processes in practice.
