Abstract
Objective
To describe the knowledge and self-perceived skills of endemic disease control agents before the specific technical training of the Health with Agent Program (PSA).
Method
Descriptive study using data from students of the Health with Agent Program, collected through a self-administered online questionnaire. The instrument included sociodemographic characterization and self-perception of skills in four domains: (a) education, planning, and actions within the community, (b) environmental surveillance, (c) epidemiological surveillance, and (d) health surveillance and two dimensions: (1) needs recognition and action planning, and (2) execution, with responses on a Likert scale. Data were analyzed using R statistical software (version 4.4.1) and presented as absolute and relative frequencies.
Results
The sample included 3,730 endemic disease control agents, of whom 51.8% were women, 67.0% were Black, 49.7% had completed high school, and 67.9% had direct formal affiliation with the municipality. Of the total, 90.6% worked in urban areas, and 39.7% were from the Northeast region. Self-perceived competence ranged from 47.0% to 94.0%. The highest self-perceived proficiencies were observed in educational activities on endemic disease prevention (90.3%), pesticide application (90.5%), and vector control (94.0%). The lowest levels were observed in environmental surveillance, particularly regarding damage from climate events and the utilization of organic waste, with more than 50.0% of participants reporting that they did not know how to perform the tasks, had limited knowledge, or had doubts.
Conclusion
The results indicate that, although endemic disease control agents perceive themselves as competent in traditional endemic control initiatives, there are gaps in emerging areas such as environmental surveillance.

Introduction
Endemic disease control agents (Agentes de Combate às Endemias, ACE) play a fundamental role in disease surveillance and control in Brazil, acting in communities to identify and reduce health risks. Their responsibilities include entomological and malacological research, environmental management, monitoring of environmental factors, and educational and community mobilization activities. In addition to technical expertise in vector control, endemic disease control agents need to work in an integrated manner with primary health care and understand the social determinants of health (1).
Significant structural challenges hamper the work of endemic disease control agents. Fragmentation of surveillance activities results in a lack of coordination across sectors, services, and professionals, leading to isolated and poorly coordinated practices. This compromises the effectiveness of interventions due to difficulties integrating with primary health care, unclear or overlapping responsibilities, and the absence of effective communication flows for joint planning (2–5).
Training for endemic disease control agents has focused on operational training, particularly in identifying and eliminating disease-vector breeding sites, such as those associated with dengue, malaria, and leishmaniasis (3,6). Although this approach has contributed to outbreak reduction, its limited scope restricts the role of endemic disease control agents in broader collective health strategies (5). The lack of effective integration between endemic disease control agents and primary health care teams compromises the effectiveness of public health interventions.
The shared responsibilities between endemic disease control agents and community health agents were established in the 2017 national primary health care policy (7) and reinforced by the technical guide on the integration of health surveillance and primary health care (8). Shared responsibilities include developing health promotion and disease prevention activities and providing community guidance on symptoms, risks, and disease vectors. Agents also play a key role in informing and mobilizing the community to implement simple environmental management measures and other environmental interventions beyond vector control (7,8).
As part of the strengthening and qualification of the Brazilian Unified Health System (Sistema Único de Saúde, SUS), the Health with Agent Program (Programa Saúde com Agente, PSA) was established by the Ordinance GM/MS No. 3,241/2020, aimed at the specialized training of endemic disease control agents and community health agents (9). It was the first technical course offered by the Ministry of Health (Ministério da Saúde, MS) with positions distributed nationwide, aligned with the national primary health care policy and, more recently, with the national directive for integrating these two professional categories (7,1).
The Health with Agent Program (PSA) is structured with theoretical activities in a virtual learning environment and supervised field practices, promoting the articulation between technical knowledge and local context. The theoretical stage is divided into two parts: the first covers topics common to both endemic disease control agents and community health agents, and the second focuses on area-specific knowledge. This training encourages the development of essential competencies in environmental, epidemiological, and health surveillance (10).
In the context of the Health with Agent Program (PSA), this descriptive study aimed to present the self-perceived knowledge and skills of endemic disease control agents before the specific technical training. The study helps identify knowledge gaps and supports the improvement of professional qualifications, in alignment with the guidelines for continuing health education. The results may inform more effective, context-specific educational strategies, thereby strengthening public health surveillance policies in Brazil.
Methods
Study design
This study is part of the research project entitled “Training in the Health with Agent Program and its impact on community health.” The objective was to describe the self-perceived skills of students enrolled in the technical course in health surveillance, prior to the specific training intended exclusively for endemic disease control agents, to identify training gaps to support the technical qualification of these professional categories, and to inform curricular adjustments.
Setting
The study was conducted within the scope of the Health with Agent Program (PSA), an initiative of the Ministry of Health (MS) aimed at the technical training of endemic disease control agents and community health agents nationwide. The course is structured in two stages: the first, common to both professional categories, and the second, specific to each category.
Participants
This study included exclusively endemic disease control agents enrolled in the technical course in health surveillance with an emphasis on endemic disease control (42,976 individuals). Participation was voluntary and preceded by acceptance of the informed consent form in digital format, agreement to which was a prerequisite for access to the questionnaire on self-perceived skills related to work as an endemic disease control agent.
Data were collected via a self-administered online questionnaire sent by email to students in the sixth month of the course, with responses accepted from 8 February 2023 to 28 March 2023.
Variables
The following sociodemographic variables were assessed: sex (female, male, and prefer not to disclose/other), race/skin color (categorized according to the Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatística, IBGE) as: Brown (Brazilian mixed race), Black, White, Asian, Indigenous, and prefer not to disclose), age (in years, categorized as: 20–29, 30–39, 40–49, 50–59, and ≥60 years), educational level (incomplete high school, complete high school, incomplete higher education, complete higher education, incomplete postgraduate education, and complete postgraduate education), macroregions (Northeast, Southeast, North, Central-West, and South), work setting (urban area, rural are, riverside community, Indigenous community, and other), length of service as an endemic disease control agent (in years, categorized as: 0–2, 3–5, 6–10, 11–15, 16–20, and >20 years), and work affiliation (direct formal affiliation with the municipality, direct formal affiliation with the state, outsourcing contract, do not know/prefer not to disclose, and other).
The skills of endemic disease control agents were investigated through four main domains of the self-perceived skills questionnaire: (a) education, planning, and activities within the community, (b) environmental surveillance, (c) epidemiological surveillance, and (d) health surveillance, subdivided into two dimensions: (1) recognition of needs and action planning and (2) execution of activities. A total of 25 items from the self-perceived skills questionnaire were used, with responses on a five-point Likert scale (“do not know how to do it,” “know a little how to do it,” “have some doubts,” “know how to do it,” and “know very well how to do it”).
Data sources and measurement
Data were collected using a structured questionnaire developed specifically for this study, comprising two main sections: sociodemographic profile and self-perceived skills of endemic disease control agents. The instrument did not undergo a full psychometric validation process; however, its development followed a rigorous methodology, divided into four stages, described below:
Stage 1: bibliographic review conducted in October 2022 in the Virtual Health Library (Biblioteca Virtual em Saúde, BVS), including publications from 2018 to 2022 and documents such as pedagogical projects, national primary health care policy guidelines, and legislation relevant to the professional responsibilities of endemic disease control agents.
Stage 2: construction of the instrument, organized into six domains: education, planning, and actions within the community; work process; environmental surveillance within the community; epidemiological surveillance within the community; health surveillance within the community; and first aid. These domains encompass the technical competencies required, understood in this study as the manifestation of “know-how,” corresponding to the ability to mobilize cognitive, socio-affective, and psychomotor resources to address complex situations (11). Each skill was assessed according to two dimensions, termed “recognition of needs and action planning” and “execution,” using a five-point Likert scale: “do not know how to do it,” “know a little how to do it,” “have some doubts,” “know how to do it,” and “know very well how to do it”.
Stage 3: content and semantic structure validation conducted by eight specialists holding doctoral degrees and with experience in the field, in accordance with Lynn’s methodological recommendation, which establishes ideal participation between five and ten experts.
Stage 4: face validity assessment conducted with 15 professionals, randomly selected from among endemic disease control agents and community health agents. All participants had at least 6 months of professional experience and were actively employed in their positions. The objective was to assess clarity, comprehension, and relevance, and to collect suggestions for improving the questionnaire.
The final instrument comprised 47 items distributed across six domains. For this study, 25 items belonging to four of these domains were selected (described in the subsection “Variables”).
Bias
Due to online data collection and the self-administered nature of the questionnaire, selection and information biases may be present; these are discussed in the Discussion section, which addresses the study limitations. Measures were implemented to minimize bias, including excluding duplicate responses and refusals.
Study size
Among enrolled students who accessed the questionnaire during the available period, 51 chose not to participate in the study; 588 duplicate responses were identified and excluded; and 440 participants did not fully complete the skills assessment questions. The final sample comprised 3,730 participants. No probabilistic sampling was performed, and a convenience sample was constituted within the eligible population.
Quantitative variables
Continuous quantitative variables, such as age and length of service, were categorized into predefined ranges to facilitate analysis and minimize distortions from extreme values. The categories were established based on intervals relevant to participant characterization and were also consistent with the available literature.
Statistical methods
Data organization and cleaning were performed using Microsoft Excel. Statistical analyses were conducted using R software, version 4.4.1. Absolute and relative frequencies were calculated for categorical variables and for the domains and dimensions of the assessed skills. Only complete responses were considered valid.
Results
Of the 3,730 participating endemic disease control agents, 51.8% were female. The Black race/skin color group (Black and Brown) predominated, accounting for 67.0% of the sample. Nearly half of the sample (49.1%) had completed or were in the process of completing higher education, including postgraduate degrees. Most participants (90.6%) worked in urban areas, and 39.7% were concentrated in the Northeast region. A total of 67.9% had a direct formal affiliation with the municipality. The predominant age group was 40–49 years (39.9%). Regarding length of service, 25.7% had 11–15 years of work experience (Table 1).

Epidemiological surveillance and community-based planning skills showed high levels of self-perceived competence, with 79.1% for action records and 94.0% for control of vector-borne diseases. Indicators related to workers’ health ranged from 58.8% to 61.4% among those who reported knowing how to perform the activities (Table 4).
Health surveillance indicated high rates of self-perceived mastery in identifying and guiding on zoonoses (84.8%), sanitary inspections (82.3%), and pesticide application (90.5%). Regarding improper waste disposal, risk of collapse, and consumption of unsuitable products, between 59.9% and 67.5% of endemic disease control agents reported mastery of the assessed practices. Between 2.5% and 7.8% reported a lack of competence in the activities (Table 5).
Discussion
Most of the endemic disease control agents investigated in this study reported high confidence in activities related to the prevention and control of endemic diseases, epidemiological surveillance, and pesticide handling. However, gaps were identified in environmental surveillance, particularly in the management of damage from climatic events and in the utilization of organic waste.
The methodology, based on self-reported questionnaires, although subject to overestimation bias in competencies, proved reliable in identifying areas of mastery and weaknesses, as the internal consistency of the findings supported both indicators of excellence and the difficulties reported (12).
Although the sample consisted of students enrolled in a technical course with remote classes, online data collection may have limited participation among individuals with limited access to and fluency in digital technologies, potentially underrepresenting more vulnerable groups or those with lower educational attainment (13).
The study advanced in demographic terms, considering that the literature is predominantly limited to small-scale regional studies (14,15).
Although this study did not include an objective assessment of skills, it is recognized that each scientific investigation offers a specific perspective on the phenomenon under study, contributing particular elements to a broader understanding of the topic. The findings presented herein provided important evidence regarding the self-perception of endemic disease control agents.
A significant increase in female participation in the profession, which has historically been male-dominated, was observed, corroborating findings from previous studies and trends in other health occupations (14,15). The predominance of individuals aged over 40 years, combined with an average length of service exceeding 10 years, suggested an experienced workforce, a factor that may favor the quality of professional practice (5,14,15). The ongoing need for continuing education strategies aligned with the National Permanent Health. Education Policy (Política Nacional de Educação Permanente em Saúde, PNEPS) emphasizes updating knowledge and practices in light of technological advances and emerging demands (16–18).
Most endemic disease control agents self-identified as having Brown race/skin color, which, together with those who self-identified as Black, composed the contingent of Black individuals within this professional category. This racial composition is consistent with previous studies on the sociodemographic profile of endemic disease control agents and community health agents in Brazil, reflecting the predominant inclusion of Black individuals, particularly in community-based roles (19).
The predominant educational level observed in this study was consistent with the minimum requirements for the position, and a significant proportion of participants had educational attainment above the minimum, indicating potential for professional qualification and the expansion of technical competencies within the category (14,15,19). The importance of continuing training and professional valorization policies that account for educational heterogeneity and encourage the development of critical and intersectoral skills is highlighted (1,19).
In this study, endemic disease control agents reported mastery of most activities. The lowest levels of perceived mastery were observed in environmental surveillance, particularly regarding environmental damage from heavy rainfall, drought, air quality, and the utilization of organic waste. Lower self-perceived proficiency, including in the field of education, was also observed in the planning and execution of environmental activities. This gap may stem from the historical emphasis on short, informal operational training and from structural challenges within the Brazilian Unified Health System, such as a lack of clarity regarding the responsibilities of endemic disease control agents and challenges in implementing intersectoral actions (20–23).
Fragmentation between endemic disease control agents and community health agents exacerbates this limitation, compromising the effectiveness of surveillance actions and community adherence. Organizational and procedural barriers, such as the absence of communication flows or integrated protocols, also hinder coordination between primary health care and health surveillance (2,24,25). Overcoming this fragmentation requires articulating competencies within integrated work models that combine generalist and specialized functions, thereby strengthening territorial linkage and responses to the social and environmental determinants of health.
The relationship between health and the environment has been recognized since 1986, following the 8th National Health Conference (8ª Conferência Nacional de Saúde), and was consolidated in the 1988 Constitution and in Law No. 8,080/1990 (26,27), which defines environmental surveillance as a fundamental component of the Brazilian Unified Health System. Despite this, endemic disease control has historically focused on isolated actions, without comprehensively addressing the social and environmental determinants of health (23). The reorganization of the Health and Environment Surveillance Secretariat (Secretaria de Vigilância em Saúde e Ambiente, SVSA) (Decree No. 11,358/2023) (28) and the incorporation of endemic disease control agents into primary health care through the 2017 National Primary Health Care Policy represent milestones in expanding the responsibilities of these professionals in environmental surveillance and workers’ health (7).
This study showed that the highest levels of self-perception were concentrated in vector control activities, educational activities, and pesticide handling, reflecting a reactive, campaign-based sanitary model of action (4). This dynamic has been observed in dengue control and in investigations on leprosy and Chagas disease (29,30), suggesting a consistent pattern of siloed practice. To overcome this compartmentalization, it is essential to train endemic disease control agents in the planning and execution of intersectoral actions, thereby promoting the valorization of integrated territorial practices.
The need to intensify coordination between primary health care and health surveillance through initiatives such as the Health with Agent Program (PSA) is reinforced, with a view toward a more resolutive and participatory Brazilian Unified Health System (SUS). This strategy contributes to the transition from the traditional model of “endemic disease management,” characterized by pesticide use, to a model of “endemic disease control” grounded in territorial actions and population-based environmental education, which requires a long-term process of structural change (1,15,20).
This study conducted a situational analysis prior to technical training for endemic disease control agents within the Health with Agent Program (PSA), highlighting consolidated competencies and specific training needs. These findings may guide curriculum development and support pedagogical strategies targeted at the identified gaps, contributing to integrated and qualified training within the scope of the Brazilian Unified Health System (SUS).
