Aim:

To analyze the spatiotemporal dynamics and socioeconomic factors associated with the incidence of congenital syphilis in the Brazilian Northeast from 2008 to 2018.

Method:

An ecological study conducted on cases of congenital syphilis in the Northeast and notified in the Information System of Notifiable Diseases. Methods of temporal and spatial analysis were applied to identify trends and clusters of the disease as well as a model of linear regression to point out indicators related to congenital syphilis with a 5% significance level.

Results:

The incidence of congenital syphilis has significantly increased in all states of the Northeast (p<0.001), with higher indexes and clusters mostly in municipalities of the coast region. The variables associated with the incidence of congenital syphilis in the Northeast were: percentage of alive newborns with low birth weight (p<0.001), Human Development Index (p<0.001), income per capita (p<0.001), percentage of poor people (p<0.001), percentage of people with 18 years or more with complete basic education (p<0.001), and illiteracy rate (p<0.001).

Conclusion:

it was verified that incidence of congenital syphilis during the period analyzed and high indexes clusters in the coast of the Northeast coast.
