This article analyses the process of construction of Health Surveillance in Brazil concerning the political, historical and organizational context of this component of the Unified Health System (UHS), by means of its historical view and presentation of the advances, limits, setbacks and perspectives. Throughout trajectory of Health Surveillance, its objects of study and intervention have been expanded, strengthening the integration among the different areas of surveillance, increasing its capacity for prediction and intervention. It evolved from surveillance of people, to surveillance of diseases and now to surveillance of health risks, promoting greater articulation of HS professionals with agents of endemics and Family Health Teams. The first National Health Surveillance Conference, in February 2018, provided opportunities for discussion and formulation of proposals aimed at strengthening HS, expanding its scope of actions with a view to achieving a comprehensive care model. Adequate and audacious alternatives are necessary so that there are no setbacks in the financing modalities in order to maintain and expand the advances achieved in the field of Health Surveillance in Brazil.
This research output has an Altmetric Attention Score of 4. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 07 October 2026.
All research outputs
#7,359,319
of 25,385,509 outputs
Outputs from Ciência & Saúde Coletiva
#625
of 2,037 outputs
Outputs of similar age
#120,024
of 342,877 outputs
Outputs of similar age from Ciência & Saúde Coletiva
#52
of 65 outputs
Altmetric has tracked 25,385,509 research outputs across all sources so far. This one has received more attention than most of these and is in the 69th percentile.
So far Altmetric has tracked 2,037 research outputs from this source. They receive a mean Attention Score of 3.8. This one has gotten more attention than average, scoring higher than 67% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 342,877 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 64% of its contemporaries.
We're also able to compare this research output to 65 others from the same source and published within six weeks on either side of this one. This one is in the 20th percentile – i.e., 20% of its contemporaries scored the same or lower than it.
