Improving housing, health education, the use of residual insecticides, actions to prevent transfusion transmission and pregnancy control are commonly recommended measures for control. However, Chagas disease is a complex health problem, basically related to environmental, cultural, social and economic conditions, among others. 29 some complex health problems precarious living conditions and profound ecological changes lead to situations of environmental and social risk.
This reality suggests the need to promote new approaches and knowledge based on the analysis of economic, environmental, social and health processes. Hence, the development of methodological and strategic rethinking for the prevention, control, surveillance and care of Chagas disease in each community. In this sense, community participation for the control of Chagas disease is a strategy that has been widely used with favorable results in Latin America.
The issue is often naturalized in the affected populations
What is it and how is Chagas disease transmitted? Talking about Chagas is more than naming the biological causes that trigger it. The enabling environment, cultural practices, isolation, the social and economic situation of people living with Chagas, are factors that contribute to shaping the complex reality that needs to be addressed when addressing this problem. The issue is often naturalized in the affected populations. This means that many times, it is not felt as a priority problem since there are other more urgent needs for these populations .2 In vector transmission, the disease cycle begins when the vinchuca feeds on the blood of an animal or person infected with the parasites.
Once ingested, these parasites will multiply in the intestine of the vinchuca. When it bites a susceptible individual, it can remove fecal matter contaminated with these parasites, which will enter the person’s blood through the wounds produced by scratching. From a sanitary point of view, vector transmission is the most important, since it depends on the risk of other transmission routes. It is called vector because it requires a vector, which for this disease is the vinchuca and is the one that makes possible the transmission of the parasite. In addition to vector transmission, there are two other forms of transmission that we must take into account: vertical and transfusion.
Vertical transmission occurs from a pregnant woman to her baby, through the placenta.
Transfusion transmission is the result of a blood
That is why it is so important to perform checks during pregnancy, as the baby can be successfully treated after birth. Transfusion transmission is the result of a blood transfusion with blood that was not properly analyzed. For some years now, it has been mandatory to test donor blood before another person receives it. 2. Guide to general notions to address the problem of Chagas with the community. Ministry of health of the nation. 2007. 30 COURSE IN SOCIAL AND COMMUNITY HEALTH 2. National Chagas program activity do you know this program? a. does it have a presence in your community? how is it implemented?
If implemented, how is your participation as part of the health team? If not implemented ,does the team perform any type of Chagas disease prevention activity? I collected information and share it with your course mates. The National Chagas program (PNCh) began operating in 1961, after more than a decade of research and development of several vector control pilot programs.
Since then, despite significant improvements, acute vector cases of Chagas disease have continued to be recorded due to the lack of a sustained entomological surveillance system and reinfestation of treated homes. Since the beginning of the actions against Chagas disease in our country, greater emphasis has been placed on the fight against the vector and the control of blood banks to discard the blood of reactive donors. Between 1992 and 1999, household infestation by T. infestans decreased from 6.1 per cent (1992) to 1.2 per cent (1999).
The appropriate strategy to achieve
During the same period, the control of donated blood was improved and increased, and in addition, the control of pregnant women and the follow-up of the children of infected women, as well as the control of organ donors, was standardized. 31 some complex health problems 3. Full text of the act in: since 2000, there has been an increasing trend in the number of acute vector cases in the country, among other causes as a result of reductions in the budget and operational capacity of the programme, shortfalls in human and material resources and inadequate management.
- Other factors contributing to the outbreak were the socio-economic crisis of 2001, insufficient attention to the problem and promotion and Prevention in health systems, and management changes in programmes. In order to interrupt transmission, vector and non-vector control activities need to be optimised, with ongoing active surveillance and timely diagnosis and treatment of infected persons.
- The appropriate strategy to achieve this goal should include shared commitment and responsibility between the national, provincial and municipal levels.
- This requires trained, committed and informed people who work as a team, who know who to turn to in the face of different problems and who can communicate with the population in an appropriate way. Activity we propose that you think a community approach to the problem, either for an endemic area (vector transmission) or not (vertical and/or transfusion transmission).
We invite you to share and discuss your strategy with your course colleagues and the tutor. 2.1. Law 26.281 Prevention and control of Chagas Law 26.281 (September 2007) declares of national interest, and assigns a priority -within the national health policy of the Ministry of Health and in the framework of the strategy of Primary Health Care – the prevention and control of all forms of transmission of Chagas disease, until its final eradication throughout the country.
On the other hand, it should be known
To this end, the law assigns to the National Executive the obligation to develop interventions to provide preventive and treatment responses of an environmental, labor, health, educational, housing and healthy habitat nature. 32 course in social and community health knowledge of the rules by the health team is very important, it regulates actions and mentions procedures to follow that favor the health care of the whole community.
In Argentina, it was common for concern tests to include Chagas analysis. Often, a positive result could lead to discrimination, creating a socio-economic problem added to that already possessed by the patient.
On the one hand, it is important to know that since law 26281/07 this practice can no longer be requested (as stipulated in Art. 5°). On the other hand, it should be known that a positive result for Chagas does not imply incapacity for work. A medical check-up may define a person’s state of Health. What does a positive result imply for Chagas? Confirmation that a person has been infected with T. cruzi does not necessarily imply that he will develop the disease. You may not have any health problems associated with Chagas throughout your life.
