[Analysis of the seasonality of tuberculosis in Brazilian capitals and the Federal District from 2001 to 2019]

The literature has few studies on the seasonality of tuberculosis (TB) in the southern hemisphere, entailing the fill of this knowledge gap. This study aims to analyze whether TB incidence in Brazilian capitals and the Federal District is seasonal. This is an ecological study of a time series (2001-2019) of TB cases, conducted with 26 capitals and the Federal District. The Ministry of Health database, with 516,524 TB cases, was used. Capitals and the Federal District were divided into five groups based on social indicators, disease burden, and the Koppen climate classification. The seasonal variation of TB notifications and group amplitude were evaluated. We found TB seasonality in Brazil with a 1% significance in all capital groups (Stability assumption and Krusall-Wallis tests, p < 0.01). In the combined seasonality test, capital groups A, D, and E showed seasonality, whereas groups B and C, its probability. Our findings showed that health service supply and/or demand - rather than climate - may be the most relevant underlying factor in TB seasonality. It is challenging to raise the other seasonal factors underlying TB seasonality in tropical regions in the Southern Hemisphere.

Facilities and difficulties in implementation of the tuberculosis control program in Primary Health Care

Introduction: The Brazilian National Tuberculosis Control Program was created to recommend and direct clinical actions, organizational setting, information systems and surveillance of tuberculosis. The process of implementation of control actions in Primary Care took place in several formats and with different outcomes, due to the influences of local organizational configuration. Objective: To identify the facilities and difficulties reported by nurses in the implementation of the Tuberculosis Control Program in Primary Health Care. Methods: A descriptive cross-sectional study with a quantitative approach, conducted in the city of Natal, Brazil. Data collected from November from 2017 to February 2018, with 80 nurses from Primary Health Care, through a structured questionnaire. Data were categorized according to similarity criteria and analyzed using descriptive statistics. Results: The availability of nurses to work in the program (47.5%) and the presence of materials (31.2%) were the most frequently mentioned facilities. The most frequently mentioned difficulties were: adherence to treatment (21.2%) and the performance of complementary tests (15.0%). Conclusion: The findings of the study may contribute to reflection and planning of actions by health teams, as well as a tool for local managers to organize their services, in order to ensure the person with tuberculosis comprehensive care.
