In the frontline: Disease Control Agents' role, an insight from Brazil
Vector control and environmental management are crucial aspects of dengue control, with professionals in the field delivering these interventions as thoroughly as possible and providing an essential link between communities and the health and prevention sector. However, a number of challenges mean that it can remain difficult to maintain staff numbers and momentum in these positions - globally, technical knowledge of vectors can remain insufficient, training opportunities are limited, and job prospects in this field can feel limited at the municipal level where the positions operate. There also remain significant gaps in the perception by local communities of these agents' role. In recently published work, a team of researchers have spoken to Disease Control Agents in disease-endemic regions of Brazil to gain a better understanding of their own and the public's perceptions about their role. In this Infectious Thoughts interview, we speak about the results to Cíntia Donateli from the Federal University of Viçosa, in Minas Gerais, Brazil, and how to overcome the current challenges and limitations in the work of Disease Control Agents to ultimately improve the control of disease and their vectors.
Can you describe the role of individuals which you were interviewing in this research? How important are these Disease Control Agents (ACE) for the control of disease?
Endemic Disease Control Agents (ACE) are agents with a role in disease prevention and in health promotion, both at an individual and collective level. ACE focus in Brazil is prevention and vector control, with actions of integrated environmental management which involve the execution of chemical and biological control measures, visits at households and at critical areas, such as abandoned terrains. Besides inspections in places where water accumulates, as water tanks and pools, ACE agents also act as health promoters through actions of health education. An example of these actions is the execution of activities of awareness-raising activities carried out by ACE, mainly in schools and basic health units.
The importance of ACE stems from the fact that this professional is in direct and continuous contact with the population and with the environment, which makes them the main articulators between the community and health service. Through the knowledge of territory specificities and particularities, of vulnerability and health risks mapping, ACE can act with a wide vision of health determinants and the environment.
Vector control and environmental management are crucial aspects of dengue control, with professionals in the field delivering these interventions as thoroughly as possible. Why was it important for you to speak directly to the professionals involved in delivering these interventions in the field?
Given the successive epidemics of arboviruses, it is essential to examine the factors that potentiate and hinder ACE fieldwork, seeing that ACE agents are primordial in the process of change and transformation in the way of managing the environment and of fomenting vector control together with the community. Only by recognizing ACE professional practice and the inherent challenges in its work process will we be able to understand the dimension and complexity of their activities and establish priorities and more efficient goals in the control of arboviruses.
Thus, in ACE’s own perspective, from the issues that are crucial for the realization of territory interventions we will be able to reflect critically about the current approach of disease prevention and vector control, which is currently focused in immediate actions that they point out as non-effective and without long term outcomes.
What are the main challenges that Disease Control Agents face in their work?
The challenges of ACE’s professional practice are innumerous. We identify the following as some of the main challenges: the lack of recognition about the professional performance and the non-comprehension of this professional’s role by population, the disqualification and unpreparedness for field work (lack of capacitation and adequate training in time and contents), coupled with poor working conditions, such as incipient infrastructure and shortage of materials which undermine the quality of executed activities.
