THE REEMERGING PROFILE OF PERTUSSIS IN BRAZIL AND ITS IMPACT ON CHILDREN’S AND TEENAGER’S HOSPITALIZATION
Abstract
Background and Aims
Pertussis is an acute bacterial infectious disease responsible for high rates of infant morbidity and mortality, despite the national vaccination program, which concerns the public health agencies. The objective of this study is to analyze the epidemiological profile and behavior of pertussis hospitalizations in Brazil and point out the importance of health surveillance.
Methods
Data were collected using the Hospital Information System (SIH). The study population were children and teenagers from zero to 14 years old diagnosed with pertussis from 2007 to 2020 in Brazil. The variables analyzed were hospitalizations and deaths throughout the years, age group and hospitalization time.
Results
In the period analyzed, 22. 279 pertussis hospitalizations were reported among children. The highest number of hospitalizations (87.51%) and deaths (92.68%) were registered among those under 1 year old, also responsible for 90.08% of the total hospitalization time. Over the years, was verified a significant increase in hospitalizations, with the highest number registered in 2014 and a decrease from 2020.
Conclusions
Despite the systematic vaccination of children started in the 1980s, pertussis has been showing a reemerging profile in Brazil. This scenario appears to be related to genotypic changes in bacteria, a greater number of asymptomatic carriers and improvement in laboratory diagnosis. This is an alarming context, especially to children under 1 year of age, vulnerable to a serious and fatal infection. Therefore, is important to monitor the disease through epidemiological surveillance to aid strategies in education and access to health through public policies.
