Introduction: Zika is an emerging arboviral disease that entered Peru in 2016, associated with congenital malformations and neurological complications. Objective: To analyze the incidence and distribution of Zika and identify complications in pregnant women in Peru during the 2016–2023 period. Materials and methods: Observational, descriptive study based on secondary data from the national epidemiological surveillance system. Annual incidence rates (AIR) and average annual incidence rates (AAIR) were calculated by age group, sex, and geographic region. Results: A total of 4529 confirmed cases were reported (national AAIR: 2.62 per 100,000 population), with an epidemic peak in 2019 (AIR: 11.03 per 100,000). Focal outbreaks were identified in 12 departments, with the highest burden in Cajamarca (AAIR: 17.42) and Loreto (AAIR: 11.59). The highest AAIR was observed among young adults (2.04...

Introduction: Dengue, a disease widely distributed in Peru, has increased incidence in recent years. Objective: Identify the population that resides in transmission scenarios, analyze the evolution of dengue and its association with demographic and socioeconomic factors. Materials and methods: Descriptive, cross-sectional, ecological study, using data from secondary sources of cases and demographic and socioeconomic information, publicly accessible; units of analysis at the district and national level, period 2010-2023. Incidence, fatality and mortality rates are estimated, and the association between cases and demographic and socioeconomic variables is analyzed. Results: At the national level, in the period 2010-2023, 606,266 cases were reported from 602 districts (408 with continuous transmission and 194 with sporadic cases), 75% of the national population resides in these scenarios.
