“…[20][21][22] In 2008, Basso et al 23 reported that the prevalence of E. coli and E. nana has increased in recent decades compared to that of other intestinal parasites; the authors explained that this increase may be related to the transmission mode of infective cysts through stool, which facilitates interpersonal contamination, even in environments with good sanitary conditions. Another factor that must be considered is that the presence of protozoan cysts in human stool is usually not an indication for treatment 22 , thus making interpersonal contamination more difficult to prevent. By contrast, the low prevalence of helminthes found in this study can be attributed to improvements in public health, sanitation, housing, and education.…”

RESUMOOBJETIVO: A prevalência de enteroparasitoses é pouco relatada em estudos com a população idosa. Sendo assim, esse estudo teve como objetivo identificar a prevalência de enteroparasitoses associadas a fatores sociodemográficos e de saúde em idosos da Estratégia Saúde da Família (ESF). MÉTODOS: Estudo transversal, realizado com uma amostra aleatória de idosos da ESF do município de Porto Alegre. A coleta de dados foi realizada pelos agentes comunitários de saúde, que aplicaram um questionário geral de inquérito epidemiológico. A coleta de sangue e fezes foi realizada pela equipe do projeto, na unidade de saúde onde o idoso estava cadastrado. RESULTADOS: Foram avaliados 581 idosos e a prevalência de enteroparasitoses foi de 10,8%. Os parasitos encontrados foram: Endolimax nana (42,7%), Entamoeba coli (33,8%), Giardia lamblia (8,8%), Ascaris lumbricoides (5,9%), Strongyloides stercoralis (4,4%), Trichuris trichiura (2,9%) e Iodamoeba bütschlii (1,5%). CONCLUSÃO: A prevalência de enteroparasitoses foi baixa quando comparada com outros estudos e com predomínio de parasitos não patogênicos. Esses achados sugerem a possibilidade de transmissão interpessoal, contaminação ambiental ou mesmo a ocorrência de ingestão de alimentos ou água contaminados. Estes resultados ressaltam a importância da implementação de medidas relacionadas ao saneamento básico e programas contínuos de educação sanitária na comunidade estudada. PALAVRAS-CHAVE: enteropatias parasitárias; idoso; saúde pública. ABSTRACT OBJECTIVE:There are few studies on intestinal parasitic infections in elderly populations. Therefore, this study aimed to determine the prevalence of intestinal parasites and identify the association between this prevalence and the sociodemographic, environmental, and health factors of the elderly attended by the Family Health Strategy (FHS). METHOD: This cross-sectional study involved the analysis of data collected from a random sample of elderly individuals. Community health workers drafted a general questionnaire to collect epidemiological data. The project team also collected blood and stool samples at the healthcare unit where each individual was enrolled. RESULTS: Among 581 elderly people, the prevalence of intestinal parasites was 10.8%. The parasites found were as follows: Endolimax nana (42.7%), Entamoeba coli (33.8%), Giardia lamblia (8.8%), Ascaris lumbricoides (5.9%), Strongyloides stercoralis (4.4%), Trichuris trichiura (2.9%), and Iodamoeba bütschlii (1.5%). CONCLUSION: The prevalence of intestinal parasites in elderly persons was lower than that reported in other studies, and the parasites identified were predominantly non-pathogenic. The findings suggest the possibility that interpersonal transmission, environmental contamination, or the ingestion of contaminated food or water is occurring in this population. These findings also highlight the importance of the ongoing implementation of sanitation and hygiene education programs in this community.

“…This fact hinders from handwashing until the hygienic preparation of food, making them more susceptible to infection and potential transmitters of diseases caused by bacteria, viruses, and parasites (Rane 2011). Other authors (Capuano et al 2002;Takizawa et al 2008) evaluated the occurrence of intestinal parasites in food handlers of several occupational categories, and also detected a high prevalence (47.7 and 37.8%, respectively) among mobile vendors despite they have analyzed a lower number of individuals in relation to the total registered in their localities. Among verified parasites, there was the predominance of protozoa relative to helminths.…”

“…These have been reported at high percentages in different occupational categories classified according to the nature of work -hospitals, restaurants, bakeries, schools, and street fairs (Rezende 1997;Nolla & Canto 2005;Carneiro 2007;Takizawa et al 2008;Zaglool et al 2011;Teferi et al 2012). The importance of handlers in the spread of diseases becomes more pronounced, especially under poor hygiene (Carneiro 2007), since these individuals can be a lasting and silent source of infection (Silva et al 2005).…”

“…Despite the importance of street food vendors to public health, studies are lacking, especially in Brazil, addressing the presence of intestinal parasites in these individuals (Capuano et al 2002;Takizawa et al 2008). In Maringá, study area, the data obtained for intestinal parasites showed, in the general population, the frequency of 14%, although the municipality has adequate sanitation, as treated water and sewage for about 70% of the population (Faria et al 2007).…”

In this study, the prevalence and risk factors for enteroparasites were determined in food handlers from Maringá, Paraná State, southern Brazil. Fecal and subungual materials of 150 street food vendors were analyzed by the methods of Lutz, Faust, and Mello, respectively. A questionnaire on hygiene and sanitary conditions of the workplace and of domicile was applied. The prevalence of enteroparasites was 28%, and the protozoa infection was more expressive (21.3%) than by helminths (6.7%), but without significant difference (p > 0.05). Entamoeba coli was the most frequent species occurring in 15.3%, while the prevalence of protozoa pathogenic was low (Giardia lamblia: 2.7% and Entamoeba histolytica: 0.7%). The subungual material presented negative results. The presence of pets in domiciles has increased twice the risk of infection. The working conditions of the majority of street food vendors were inappropriate. The results highlight the need for more rigorous programs of continuing education, parasitological examination every six months, and health surveillance. In this way, the quality of the service provided to the population can be improved and the transmission of food-borne diseases can be prevented.

“…This study was based on a sample from an underprivileged population in which a high prevalence of giardiasis was largely observed when compared to studies done in other cities in Brazil 4,5,[7][8][9][10][11][12][13][16][17][18][19] . It is part of an "Extension Project to the Community" where two undergraduate students voluntarily worked on weekends, trying to make the community aware of the importance of health care.…”

SUMMARYEnteric parasitosis remains an important public health problem in many areas around the world including in Brazil, and it is frequently associated with poverty and lack of sanitation facilities. Research carried out over the course of a year revealed that 96.6% (28/29) of children randomly selected from a 'landless farm workers' settlement in Araras, São Paulo, aged 4 -15 years, presented Giardia intestinalis cysts. After referral to the neighborhood Health Office, all the children received tinidazole, given as a single dose of 50 mg/kg and 12 months later, new fecal samples were collected and analyzed. Despite the low adherence to the study, a high percentage (64.3% -9/14) of the children remained positive for the parasite. This study showed a high positivity of giardiasis in child residents of the settlement, even after treatment; adults were not sensitized to the study and did not collected and/or deliver children fecal samples. The precarious living conditions are consistent with a high susceptibility to parasitic diseases, suggesting that the treatment of the infected individuals without identifying and eradicating the means of contamination is simply a palliative measure.
