The objective of the study is the epidemiological analysis of hepatitis B in the State of
Pará, from 2010 to 2020. It is a cross-sectional, descriptive, retrospective study with
a quantitative and documental approach based on the records of cases of hepatitis B
notified in the System of Information on Notifiable Diseases, available for consultation
in the database of the Department of Informatics of the Unified Health System
(DATASUS). A total of 2,759 cases were found and the analyzes of the variables
were divided into: sociodemographic profile (geographical distribution, sex, age
group, race, education, in addition to the evaluation of the special population of
pregnant women and vertical transmission) and clinical profile of the disease
(hepatitis acute, chronic, fulminant and undefined cases). According to the analysis
of the variables, the following results were observed: the analysis of the
sociodemographic profile pointed to the region of the lower Amazon, Carajás and
Metropolitana I as the region with the highest prevalence, with 1,846 cases (67%);
the predominant female gender with 1,401 (67%) cases; the age group from 20 to 39
years old with 1,333 (49%) cases; schooling with complete secondary education with
576 (21%) cases, brown race with 2,213 (81%) cases. Among the special population
of pregnant women, 519 (18.1%) cases were reported, with the second trimester
being the most prominent with 219 (42%) cases. Finally, the evaluation regarding
vertical transmission with about 18 (0.6%) cases. In view of this, it is concluded that
hepatitis is still a public health problem in the northern region of the country and in
the state of Pará, requiring measures such as expanding testing, increasing
vaccination coverage and education in reproductive health, since transmission sexual
is still the most frequent.
