“…Similar results were found in the literature for studies conducted in the northeastern region of Brazil that showed higher prevalence rates for S . mansoni in males; the studies also suggested that the reason for these higher prevalence rates was possibly because males attended health services less frequently [ 37 , 38 , 39 ].…”

Socioenvironmental factors associated with Schistosoma mansoni infection and intermediate hosts in an urban area of northeastern Brazil

Schistosomiasis, which is caused by trematodes of the genus Schistosoma and by the species Schistosoma mansoni in Brazil, is transmitted primarily by Biomphalaria glabrata mollusks. Infections occur in humans and mollusks in freshwater environments contaminated with feces from infected humans. This study aimed to evaluate potential foci of schistosomiasis based on the identification of infection sites for the snails, factors that increased the human infection probability of S. mansoni infection, and the relationship of the disease with abiotic, biotic, and sociocultural factors. The study was conducted in an urban area on the northeast coast of Brazil; this location was chosen based on the following factors: the presence of B. glabrata, nearby freshwater, and the absence of sewer treatment. A parasitological analysis was performed to evaluate infections of the mollusks and residents inside the perimeter defined by the collection points. Questionnaires were applied to obtain demographic data and to identify behaviors that led to human infection. To verify the contamination of freshwater by human feces, a microbiological analysis of the water was performed at the mollusk collection points to determine the rate of contamination with fecal coliforms. A total of 10,270 B. glabrata mollusks were collected between August 2013 and August 2014, of which 8.8% were positive for S. mansoni; the prevalence ranged from 0 to 34.5% over the study period. A total of 232 coprological samples from the residents were analyzed. The S. mansoni infection prevalence rate was 16.4%, and the S. mansoni parasitic load in the infected residents was 54.9 eggs per gram of feces on average. Males were more affected by the parasite, especially in the 8-17-year-old age range. Thermotolerant coliforms were observed at the mollusk collection sites, which indicated that freshwater and sewage were in continuous contact. This contamination indicated poor sanitary conditions, as was previously observed, which could be combined with detrimental behavior due to the residents' habits. These conditions cause a predisposition for both intermediate and definitive infections of the hosts by creating a socioenvironmental scenario that is conducive to the formation and maintenance of potential schistosomiasis foci. This and similar areas deserve special attention from the government with an aim of improving sanitation services and local resident knowledge to prevent future contamination.

“…The high cure rate ensures the life of the patient and prevents serious complications of the disease. According to Vidal et. al (2011) it is important that in the treatment of the individuals infected with schistosomiasis, be avoided the worsening of the clinical condition and, consequently, the death.…”

Schistosomiasis mansoni (MS) is a parasitic disease that spreads through water, the trematode Schistosoma mansoni being its etiological agent. This is a serious public health problem worldwide. This paper proposes to analyze the epidemiological profile of cases of schistosomiasis in the municipality of Mulungu do Morro, Bahia, from 2007 to 2017. This is a descriptive epidemiological study of quantitative nature with data collected from the Notification Disease Information System ( SINAN) of the Unified Health System (SUS) regarding information on the number of reported cases and sociodemographic characteristics, where we analyzed the variables: gender, age, race, education, relationship with work and area of residence in the years surveyed, as well as pathology related data such as evolution and clinical form. Research shows that within the region, Mulungu do Morro occupies the 2nd place in number of notifications, with 59 cases of the disease in the period studied. The data show the predominance of males (64.4%), the economically active age group, from 15 to 50 years old (72.8%), cases from rural areas (79.7%) and from educated people. elementary school incomplete and complete (71.1%). Regarding the forms and evolution of the disease, both intestinal form and cure appear with 84.7%. The paper concludes that socioenvironmental factors are determinant for the maintenance of schistosomiasis in Mulungu do Morro municipality, providing subsidies for the formulation of strategies to combat the disease. Therefore, integrated actions between surveillance and medium-and long-term primary care should be implemented with the participation of the public and community sectors, ranging from the preparation of health professionals and the provision of tests for early diagnosis, the guarantee of treatment. to those infected in a timely manner, health education, even improvements in basic sanitation and supply of treated water, aiming to reduce the number of cases of the disease in the municipality.

“…29 About schistosomiasis, the stigmatization of this man is very worrisome because some studies indicate that the predominance of cases of the disease is related to the male gender. 35,37,39 Culturally, men are not in the habit of seeking medical care because they are known as "strongest individuals." However, when vulnerable individuals (fishermen, for example) do not seek the health service for proper diagnosis and treatment, this may favor the occurrence of severe forms of schistosomiasis and may also help maintain outbreaks of the disease by means of asymptomatic individuals with low parasitic load.…”

“…The treatment does not prevent reinfection, and therefore, it is necessary to identify the risk factors of schistosomiasis to make the control strategies more effective. 39,52,53 It is also important that education activities focus on both infection prevention and the risk of reinfection. It is necessary to explain that medicine does not prevent the individual from being contaminated again by the worm.…”

Schistosomiasis is a serious public health issue in the world infecting more than 200 million people. In Maranhão state, Brazil, the disease has a high prevalence in the Baixada Maranhense microregion, where the socioeconomic conditions, high prevalence of freshwater snails, elevated incidence of human infection, and large rodent populations make the area highly conducive to the life cycle and persistence of schistosomiasis. The objective of this study was to record the perception of residents and health/public education professionals regarding this parasitosis and also understand their knowledge of the relationship between schistosomiasis and the environment. We conducted 53 interviews addressing the socioeconomic, behavioral, and environmental issues surrounding schistosomiasis. It was recorded that the population believed the environment is the main cause of the disease and the fisherman may be stigmatized by their chance of having the disease. Health/public educational professionals in the region indicated that there were no regular educational campaigns, which contributed to the high rates of reinfection and the difficulties in preventing and controlling the spread of the disease. These data clearly demonstrate the need for interdisciplinary work that engages the community in gathering and disseminating knowledge and developing solutions to minimize the occurrence of this major health issue in the region.
