Objectives: To identify the association between the number of informal workers and the number of positive COVID-19 cases in Peru. Methods: Data from the National Institute of Statistics and Informatics of Peru and the National COVID-19 Database were used. Bivariate and multivariate linear regression analyses were conducted to assess the relationship between the number of informal workers, population density, altitude, and the number of positive COVID-19 cases. Results: The bivariate analysis showed that the number of informal workers was significantly associated with positive cases in both high and low altitude regions (p<0.001). In the multivariate analysis, informal workers (p<0.001), population density (p=0.02), and altitude (p<0.001) were found to be associated with the number of positive COVID-19 cases. Conclusions: Informal workers are common in low- and middle-income coun...

Objective: To describe the bibliometric indicators and trends in the scientific production of the Revista de Neuro-Psiquiatría, recently indexed in Scopus. Materials and methods: A search strategy was designed to collect publications registered by Scopus between 2020 and 2024.
