Spatiotemporal trends in and challenges of addressing tuberculosis in Brazil before and after the Covid-19 pandemic, 2001–2023
Objective. To identify spatiotemporal patterns and clusters of tuberculosis (TB) in Brazil between 2001 and 2023, assess the impact of the COVID-19 pandemic on TB trends, and provide recommendations for targeted interventions. Methods. This ecological study analyzed secondary data from Brazil’s Notifiable Diseases Information System (known as SINAN), which covers all confirmed TB cases during the study period. Three main indicators were analyzed:…
Tuberculosis healthcare service disruptions during the Covid-19 pandemic in Brazil, India and South Africa
Tuberculosis (TB) is the leading infectious disease cause of death worldwide. In recent years, stringent measures to contain the spread of SARS-CoV-2 have led to considerable disruptions of healthcare services for TB in many countries. The extent to which these measures have affected TB testing, treatment initiation and outcomes has not been comprehensively assessed. We aimed to estimate TB healthcare service disruptions occurring during the COVI…
Partial recovery of tuberculosis preventive treatment in Brazil after pandemic drawback
Brazil was heavily affected by COVID-19 both with death toll and economically, with absence of a centralized Federal Government response. Tuberculosis (TB) notifications decreased in 2020 but partial recovery was observed in 2021. We have previously shown a sharp (93%) reduction in TB preventive treatment notifications among five Brazilian cities with more than 1,000 notifications in 2021. We hypothesized TB preventive treatment would also recove…
Trends in tuberculosis incidence and mortality coefficients in Brazil, 2011–2019
Objective. To analyze the temporal trend of tuberculosis incidence and mortality rates in Brazil between 2011 and 2019. Methods. This was an ecological time series study of tuberculosis incidence and mortality rates in Brazil between 2011 and 2019. Data were extracted from the Notifiable Disease Information System and the Mortality Information System, and population estimates were from the Brazilian Institute of Geography and Statistics. Trends w…
A spatial-mechanistic model to estimate subnational tuberculosis burden with routinely collected data
Reliable subnational estimates of TB incidence would allow national policy makers to focus disease control resources in areas of highest need. We developed an approach for generating small area estimates of TB incidence, and the fraction of individuals missed by routine case detection, based on available notification and mortality data. We demonstrate the feasibility of this approach by creating municipality-level burden estimates for Brazil. We …
The association between a conditional cash transfer programme and malaria incidence
Higher coverage of the BFP was associated with a reduction in the incidence of malaria. CCT programmes should be encouraged in endemic regions for malaria in order to mitigate the impact of disease and poverty itself in these settings
SP1-38 Prevalence of ADL and Iadl dependence and associated factors in elders living in long-stay institutions in Brazil
Introduction Health conditions and functionality problems related to ageing affect the ability to live independently, leading to the placement of elders in a long-stay institution. This phenomenon has been increasing in Brazil. This study analyzes functional dependence and its associated factors in this population group. Methods This is a cross-sectional study with elderly residents of long-stay institutions in four Brazilian cities. The study's …
SP1-20 Prevalence of cognitive impairment and depression and associated factors in elders living in long-stay institutions in Brazil
Introduction Cognitive impairment and depression are among the health conditions that affect the ability of the elders to live independently, leading to their placement at long-stay institutions. This phenomenon has been increasing in Brazil. This study analyzes the prevalence of these health conditions and its associated factors in elders who live at these institutions. Methods This is a cross-sectional study with elderly residents of long-stay …
