Chagas: A "Silenced and Silent" Disease That Affects the Most Vulnerable
<p><span style="line-height: 1.6em;">Transmitted by the vector insect, it is the main endemic in Argentina and is linked to poor areas. Although the program that fights and prevents the disease was declared of national interest, in two years their budget was cut in half. In Buenos Aires 51 cases of infants with Chagas disease were recorded.</span></p> <div> </div>
A report by the General Audit’s Office (AGN, for its acronym in Spanish) explained that Chagas disease "is silent due to their specific characteristics (usually no symptoms) and silenced because it mostly affects low income areas which have less capacity and visibility." Although in Argentina "1.6 million individuals were affected" and "turns into 1200 deaths per year," their resources were cut.
This condition is caused by "the infection with Trypanosoma cruzi, a parasite that is transmitted through triatomines". According to the report, it is "the main endemic in the country and is linked to environments under conditions of poverty." There are two forms of the disease: one is directly through the insect, and represents 85% of cases, and the other is non-vector, which may be by blood transfusion from pregnant mother to child during pregnancy by ingestion of parasites or organ transplant."
In accordance with the characteristics of the endemic, in 2007, "the National Chagas Program (PNCH, for its acronym in Spanish) was declared of national interest, through law 26.281 it was assigned priority to the prevention and control of disease, establishing the mandatory diagnostic testing to all pregnant women, newborns of infected mothers, children between 6 and 12 years old and the donors and recipients of organs.”
However, not only "law 26,281 was not passed" but the PNCH "lost budgetary allocation between 2009 and 2011." Respectively a sum of $ 28,420,900 for the first year and another $14,571,950 was recorded, representing a decrease of half the money in two years.
The relevant diagnostic tests on pregnant women were not performed: "The highest estimate of controls for women, who will be mothers in the public sector, is 200,000, which represented 48% of those born". In addition, as reported by the federal watchdog, in 2010 the study was conducted to newborns whose mothers were ill, 23.1% of the total amount estimated.
According to the audit, the National Program is also "responsible for issuing technical regulations for the actions of non-vector and vector controls, making the assessments, and monitoring the actions taken by the provinces and to provide inputs to the scheduled actions." However, the observations of the AGN show weaknesses in all its responsibilities.
While it is typical of the North, West and Centre regions of Argentina -13 provinces, the disease "has widespread throughout the country by internal immigration and non vector transmission." In fact, cases were reported in provinces that do not have that risk because that insect doesn’t exist. According to the report, the "143 infants with Chagas infection", detected in 2009, "51 cases" are in the City of Buenos Aires.
The watchdog states that the program presents a "weakness in the operation implemented to receive information from the provinces" on the status of the endemic and cites the example of Chaco, which "has a high risk," but nevertheless "did not provide information on controls and pregnant newborns or children up to 14 years old."
Even though "it is a discomfort directly related to social and housing conditions, there is no information on coordinated actions with other areas of government," for example, "as for housing construction or relocation in infected areas".
The report, approved this year, says that there isn’t "an entomological surveillance in relation to the study of insects. The control of the triatomines in-house remains one of the weakest aspects of the program. "In 2009 monitoring was done only in 26% of the villages in the endemic area.”
The AGN noted that "provincial programs prepare their annual goals based on the operational capacity" and that "the distribution of inputs for controlling the insect vector depends on the national availability". In response, the auditing body recommended the Ministry of Health they "provide technical and financial assistance to the provinces so that schedules are developed based on the diagnoses." In short, that these resources meet the necessary actions and not vice versa.
They also stated that the audited period (2009) "was not able to take knowledge of the implementation of measures and massive campaigns to raise social awareness on a national level on disease characteristics, number of patients, and preventive measures" among other issues.
Regarding the structure of the program it is emphasized that "the organization in three areas (Cordoba, where the National Coordination of Vector control works, provincial bases and the Ministry of Health) is carried out without a centralizing unit" this "weakens not only the relationship between the vector control and prevention activities the kissing bug, detection, diagnosis and treatment of the person concerned but ultimately the possibility of a holistic approach to the disease in its various dimensions."
