[Tuberculosis Profile in Chile: Effect of Migration, Overcrowding and Income on Tuberculosis and Its Spatial Distribution].

Aim: To analyze tuberculosis (TB) incidence, demographic profiles, and associated risk factors in migrant and national populations, in order to understand the impact of migration, overcrowding, and socioeconomic factors on TB prevalence and care-seeking behaviors.

Material And Methods: Data from various communes within the Metropolitan Region and other parts of the national territory were analyzed to assess TB incidence, demographic characteristics, and care-seeking behaviors among migrant and national populations.

Results: TB disproportionately affects males in both migrant and national populations.

[The impact of the different waves of COVID-19 pandemic in Chile across regions].

Background: The effects of COVID-19 in Chile changed over time and among regions.

Aim: To identify patterns in the impact and evolution of COVID-19 for each wave generated between 2020 and 2022 at the 16 regions of the country.

Material And Methods: Several indicators related to the pandemic, their evolution and their consequences for the health system and the health of the population were calculated.

Inequity in mortality rates and potential years of life lost caused by COVID-19 in the Greater Santiago, Chile.

Several studies have shown that, in Chile, income inequality is relevant in explaining health inequities. The COVID-19 pandemic has also had a negative impact, with higher mortality rates in those municipalities of Greater Santiago with lower socioeconomic status. We study inequity in mortality based on Potential Years of Life Lost (PYLL) in 34 urban municipalities of the Metropolitan Region (Greater Santiago) and analyze its evolution between 2018 and 2021 and by COVID-19 waves.

Factors associated with change in adherence to COVID-19 personal protection measures in the Metropolitan Region, Chile.

Personal protective measures such use of face masks, hand washing and physical distancing have proven to be effective in controlling the spread of the Covid-19 pandemic. However, adherence to these measures may have been relaxed over time. The objective of this work is to assess the change in adherence to these measures and to find factors that explain the change For this purpose, we conducted a survey in the Metropolitan Region of Chile in which we asked the adherence to these measures in August-September 2021 and retrospectively for 2020.

Identification of COVID-19 Waves: Considerations for Research and Policy.

The identification of COVID-19 waves is a matter of the utmost importance, both for research and decision making. This study uses COVID-19 information from the 52 municipalities of the Metropolitan Region, Chile, and presents a quantitative method-based on weekly accumulated incidence rates-to define COVID-19 waves. We explore three different criteria to define the duration of a wave, and performed a sensitivity analysis using multivariate linear models to show their commonalities and differences.
