Study contributions

Main results

There was heterogeneity in the distribution of hepatitis B and C detection rates between the Paraná health regions, with higher hepatitis B detection rates in the West health macro-region and higher hepatitis C detection rates in the East and West macro-regions.

Implications for services

The analysis showed the existence of priority areas for targeting strategies for hepatitis detection and prevention, service planning and organization, regarding hepatitis B and C case management in Paraná.

Perspectives

It is necessary to strengthen Primary Health Care performance, through the training of health professionals at this level of care, with a view to eliminating hepatitis B and C by 2030.

ABSTRACT

Objective:

to analyze the distribution and spatial autocorrelation of hepatitis B and C detection rates in the state of Paraná, Brazil.

Methods:

this was an ecological study of hepatitis B and C notifications held on the Notifiable Health Conditions Information System, between 2011 and 2019. Percentage change in detection rates between the first and last three-year periods was estimated. Spatial autocorrelation was analyzed using Moran’s index.

Results:

there were 16,699 notifications of hepatitis B, with a greater reduction in detection in the North (-30.0%) and Northwest (-25.9%) macro-regions. There were clusters of high occurrence in the Foz do Iguaçu, Francisco Beltrão and Cascavel regions between 2011 and 2019. There were 10,920 notifications of hepatitis C, with a greater reduction in detection in the Northwest macro-region (-18.9%) and an increase in the West (51.1%). The Paranaguá region recorded a high detection cluster between 2011 and 2016.

Conclusion:

hepatitis B and C showed heterogeneous distribution between health regions.
