Abstract

Objective to analyze the trend and spatial distribution of some diseases that require compulsory notification in pregnant women.Method ecological study, with data from the National Notifiable Diseases Surveillance System, of the incidence of the six most frequent diseases that, require compulsory notification, in pregnant women. The Prais-Winsten model was used to analyze the trend classified as stable, decreasing and increasing, according to macro-regions. For the spatial analysis, the incidences distributed in percentiles, in choropleth maps, by Health Regions were calculated.Results the most frequent infections were syphilis, dengue, Human Immunodeficiency Virus, influenza, hepatitis and toxoplasmosis. Incidence increased by 30.8%, 30.4%, 15.4% and 2.6%, on average, for syphilis, toxoplasmosis, dengue and Human Immunodeficiency Virus, respectively. On average, the incidence of syphilis increased by 40.5% in Macro-regional North and 38% in Macro-regional Northwest. The spatial analysis showed, in the last four years, high incidence of dengue, syphilis and infection by Human Immunodeficiency Virus, which reached 180.2, 141.7 and 100.8 cases per 10,000 live births, respectively.Conclusion there were increased incidences of infection in pregnant women due to syphilis, toxoplasmosis and Human Immunodeficiency Virus, with differences in their spatial distribution, indicating that these diseases should be a priority in the care of pregnant women in more affected regions.

Summary

Introduction

Decree 204, dated February 17, 2016, of the Ministry of Health (MH), establishes the diseases and aggravations of compulsory notification in Brazil and, among them, infectious diseases[1], which are still part of the epidemiological profile of the population and, when they affect women during pregnancy, may compromise their health and that of the newborn. Compulsory notification infectious diseases range from ancient diseases such as syphilis, dengue, Human Immunodeficiency Virus (HIV), Acquired Immunodeficiency Syndrome (Aids) and hepatitis, to recent infections, such as the Zika virus. A study with a population of pregnant women in a rural area of Ghana found a high prevalence of hepatitis B (16.7%) and malaria (10.6%)(2). In a municipality in Gabon, a country in the African continent, a study with 973 pregnant women found a prevalence of 2.5% for syphilis, 4.0% for HIV infection and 57.3% for toxoplasmosis[6]
