Abstract
Background: Tuberculosisis an infectious disease responsible for 1.5 million deaths, worldwide, per year. Low
levels of knowledge about TB are globally associated with a higher prevalence of latent TB infection and a low rate
of treatment success. This study aimed to evaluate the level of TB knowledge of individuals at a recreational center
in Goiânia, Goiás, Brazil.
Methods: We conducted 573 written structured interviews on recreational center frequentersin February and
March, 2013, which included fve close-ended questions and one open-ended question concerning TB. Data were
analyzed with Epi Info 3.5.2.
Results: Percentages of patients who answered questions correctly were: 96.3% knew about TB (Q1); 48.5%
knew that TB is caused by a bacterial infection (Q2); 73.8% knew that TB can be transmitted to people in contact with
infected people (Q3); 75.4% knew that TB can be transmitted via air or droplets (saliva) (Q4); 85.5% knew that the
main symptom of TB is cough (Q5); and 96.1% knew that TB is a curable disease (Q6).
Conclusion: Overall, a quarter of the population was not aware of the main symptoms, transmission mode, and
transmissibility of TB. In order to control TB infection and prevent its spread, emphasis should be placed on increasing
awareness of this disease among individuals.

Introduction
Tuberculosis (TB) is an infectious disease caused by Mycobacterium
tuberculosis and is the main infectious cause of deaths worldwide,
especially among those with a low economic status [1,2]. TB is a curable
disease and, in some countries, TB treatment has a success rate of 90%
[3]. Given the TB treatment efcacy, high rates of TB infection remains
an apparent paradox. According to Centers for Disease Control
and Prevention, some subgroups of individuals (i.e. HIV positive
individuals, alcohol consumers, and cigarette smokers) are at a greater
risk of contracting the disease [4]. In addition, incorrect treatment,
such as treatment abandonment [5,6], results in poor disease control.
Moreover, studies demonstrate that disease awareness can prevent
therapy abandonment up to 90% of the time [7]. In addition, a higher
level of education has been shown to translate to a higher level of
knowledge of TB. Specifcally, the 20 highest rates of TB are in countries
such as Zimbabwe, Cambodia, and Afghanistan (but also Brazil, China,
and Russia), which have low rates of “average years of schooling”
and “expected years of schooling” [8,9]. In addition, literature shows
that individuals with TB have a lower level of education than those
without TB [10]. Reinforcing the importance of teaching people about
Tuberculosis, World Health Organization created the Stopping TB
Operational Strategy, which focused on TB education as one of its main
objectives [11].
Tis study aimed to analyze the TB awareness in individuals in
Goiânia (a Brazilian city, capital of Goiás State). Tis analysis was
conducted through structured interviews consisting of six questions
to evaluate participants’ knowledge of cognizance, cause, transmission
mode, transmissibility, symptoms, and treatment of TB.
Material and Methods
Tis cross-sectional study included 573 frequenters of a recreational
center in Goiânia, Goiás, Brazil, and was conducted during months
of February and March, 2013. Six questions concerning common
pulmonary TB were included, covering the following topics: cognizance,
cause, transmission mode, transmissibility, main symptoms, and
treatment regimen (Figure 1). Correct answers were as follows: Yes (1),
Bacteria (2), Yes (3), through air or droplets (saliva) (4), Cough (5),
and Yes (6).We analyzed the results, comparing percentage of correct
answers with a hypothetical 100% percentage result. All data were
collected, tabulated, and analyzed using Microsof Excel 2010/2013
from Microsof, Redmond, Washington and Epi Info 3.5.2 from CDC,
DeKalb County, Georgia, USA.
Ethics
We observed the principles of autonomy, benefcence, non-
malefcence, and justice requested by Brazilian Regulatory Authorities.
Results
Participants answered 573 structured interviews: 551 (96.3%)
individuals had knowledge of TB. With regards to answering questions
pertaining to the cause of TB, 278 (48.5%) individuals referred to
bacteria; 110 (19.2%) referred to smoking; 85 (14.8%) did not know the
