PMID 41370451WHAT IT FOUND
During the pandemic, TB detection actions in São Paulo primary care changed significantly.
While more respiratory symptomatic patients were examined, the time to notify cases increased and consultation offers fluctuated. This suggests a shift in diagnostic focus that may have delayed official tracking.
Key findings
01The year 2020 saw the most significant changes in TB control actions, including a 40% change in the offer of consultations for respiratory symptoms.
02There was a statistically significant association between the pandemic period and changes in the offer of consultations for respiratory symptoms, with 2022 showing lower average change compared to 2020.
03Operational data showed an increase in the proportion of respiratory symptomatic patients examined during the pandemic years (85.13% to 90.98%) compared to the pre-pandemic period (64.27%).

What it does not show
The study was limited to one health region in São Paulo, which restricts the generalization of findings to other areas. The reliance on self-reported changes from key informants may introduce recall bias regarding the extent of service modifications during the pandemic. The exclusion of health units without TB cases during the pandemic may bias the sample toward units with higher TB activity.
Declared interests
The study was part of a multicenter project called 'Repercussion of the COVID-19 pandemic on TB in Brazilian capitals: reality and new perspectives in Primary Care'. No specific funding sources or commercial conflicts of interest were declared in the provided text.
The easy way to misread this
Do not interpret the increased examination of respiratory symptomatic patients as a sign of improved TB control; the study notes that despite this, TB incidence dropped and mortality rose, suggesting that diagnostic delays or other systemic failures may have offset the increased screening effort.
