Incomplete sanitation in the Metropolitan Region of São Paulo results in detection of SARS-CoV-2 in headwater streams. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 908:168006. [PMID: 37871821 DOI: 10.1016/j.scitotenv.2023.168006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 10/19/2023] [Accepted: 10/20/2023] [Indexed: 10/25/2023]
Abstract
Among the largest metropolitan regions in the world, the Metropolitan Region of São Paulo (MRSP) represents an important case study for the COVID-19 respiratory disease pandemic because it is home to >20 million people, making it one of the largest metropolitan regions in the global south. Besides the high population density, the MRSP has several problems related to social and economic aspects, which may reflect in the dynamics of SARS-CoV-2 virus, such as low income, lack of sanitation and social vulnerability in the peripheral regions of MRSP. In these regions, the input of untreated sewage on the streams and rivers can be frequently observed, which may represent an indicator of poor sewer system. Therefore, this study aimed to identify if streams draining urbanized regions without appropriate sanitation are prone to receive higher loads of detectable SARS-CoV-2 in its waters. For this, we collected water samples from 45 headwater streams distributed across an urbanization gradient (0-100 % of urbanization) in the MRSP, with three replicates in each stream and analyzed the concentrations of SARS-CoV-2 RNA targeting the nucleocapsid N1 and N2 genomic regions. In addition, we analyzed the relationship between the concentrations of SARS-CoV-2 RNA and sanitation and social variables. Our results showed that the concentrations of SARS-CoV-2 RNA were higher in the streams draining medium to high urbanized catchments, especially because of the lack of sanitation and the higher probabilities to detect SARS-CoV-2 RNA in the stream water was associated with households without a septic tank or sewage system within the catchment, followed by per capita household income. These results reflect the lack of urbanization planning and the lack of sanitation, especially in the poor regions from the MRSP, adding another risk for the already vulnerable population in a metropolitan region from the global south during a pandemic disease.

Snakebite envenomations and access to treatment in communities of two indigenous areas of the Western Brazilian Amazon: A cross-sectional study. PLoS Negl Trop Dis 2023; 17:e0011485. [PMID: 37440596 PMCID: PMC10368234 DOI: 10.1371/journal.pntd.0011485] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Accepted: 06/27/2023] [Indexed: 07/15/2023] Open
Abstract
BACKGROUND The indigenous populations of Brazil present poor health indicators and a disproportionate prevalence and case-fatality rate of neglected tropical diseases, including snakebite envenomations (SBEs). This study aims to estimate access to medical care for SBEs and analyze the barriers that prevent victims from accessing healthcare in indigenous communities in two health districts located in the Western Brazilian Amazon. METHODOLOGY/PRINCIPAL FINDINGS This cross-sectional study used semi-structured interviews to collect data from individuals who experienced SBEs in the Upper Rio Solimões and Upper Rio Negro indigenous health districts. Of the 187 participants, 164 (87.7%) reported that they had access to healthcare and received assistance in a hospital in the urban area of the municipalities. Frequency was 95.4% in the Upper Rio Solimões SIHD, and 69.6% in the Upper Rio Negro SIHD (P<0.0001). The study found that the availability of indigenous medicine as the only choice in the village was the main reason for not accessing healthcare (75%), followed by a lack of financial resources and means of transportation (28.1%). Four deaths were reported from SBEs, resulting in a case-fatality rate of 2.1%. CONCLUSIONS/SIGNIFICANCE In the study areas, there are records of SBE patients who did not receive medical attention. Availability of pre-hospital emergency transport using motorboats, a greater number of hospitals and better navigability of the Solimões River and its tributaries would make access easier for indigenous people living in the region of the Upper Solimões River. The implementation of cross-cultural hospital care needs to be considered in order to reduce the resistance of indigenous populations in relation to seeking treatment for SBEs.

Abstract
The Brazilian Amazon rainforest region has a significant prevalence of malarial and intestinal parasitic infections in indigenous populations, accounting for a disproportionate burden. Thus, a cross-sectional study was conducted to assess the prevalence and association between malarial and intestinal protozoan and helminth infections in four remote indigenous villages in the Brazilian Amazon Forest. A total of 430 individuals participated in the study, and Plasmodium infections were diagnosed by examination of thick blood smears and PCR. Stool samples 295 individuals (69%) were examined by direct smear and the Kato-Katz technique. The overall prevalence of malaria, intestinal protozoan infection, and intestinal helminth infection was 14.2%, 100%, and 39.3%, respectively. Polyparasitism was predominant (83.7%), and most infected individuals had at least two or more different species of intestinal protozoan and/or helminth parasites. The prevalence of co-infection was 49.5%, and in individuals with intestinal protozoa and helminth infections (34%), Entamoeba. coli, Entamoeba histolytica, and Ascaris lumbricoides were the most common parasites. In individuals with malaria and protozoa infections (10.2%), P. vivax, E. coli, and E. histolytica predominated, and in individuals with malaria, protozoa, and helminth infections (5.4%). P. vivax, E. coli, E. histolytica, and A. lumbricoides predominated. Intestinal polyparasitism was common in the study population, and the presence of helminths was associated with an increased number of intestinal parasitic species. However, Plasmodium infections were neither a risk nor a protective factor for helminth infections; the same was true for helminth infections in relation to Plasmodium. The high prevalence of intestinal polyparasitism with Plasmodium co-infections highlights the need for combining strategies that may help control both malaria and intestinal parasite and generate a health approach aligned with indigenous perspectives.

Snakebites in "Invisible Populations": A cross-sectional survey in riverine populations in the remote western Brazilian Amazon. PLoS Negl Trop Dis 2021; 15:e0009758. [PMID: 34499643 PMCID: PMC8454940 DOI: 10.1371/journal.pntd.0009758] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2021] [Revised: 09/21/2021] [Accepted: 08/24/2021] [Indexed: 12/30/2022] Open
Abstract
In the Brazilian Amazon, long distances, low healthcare coverage, common use of ineffective or deleterious self-care practices, and resistance to seeking medical assistance have an impact on access to antivenom treatment. This study aimed to estimate snakebite underreporting, and analyze barriers that prevent victims from obtaining healthcare in communities located in 15 municipalities on the banks of the Solimões, Juruá and Purus Rivers, in the remote Western Brazilian Amazon. Information on the participants' demographics, previous snakebites, access to healthcare, time taken to reach medical assistance, use of self-care practices, and the reason for not accessing healthcare were collected through semi-structured interviews. In the case of deaths, information was collected by interviewing parents, relatives or acquaintances. A total of 172 participants who reported having suffered snakebites during their lifetime were interviewed. A total of 73 different treatment procedures was reported by 65.1% of the participants. Participants living in different river basins share few self-care procedures that use traditional medicine, and 91 (52.9%) participants reported that they had access to healthcare. Living in communities along the Juruá River [OR = 12.6 (95% CI = 3.2-49.7; p<0.001)] and the use of traditional medicine [OR = 11.6 (95% CI = 3.4-39.8; p<0.001)] were variables that were independently associated to the lack of access to healthcare. The main reasons for not accessing healthcare were the pprioritization of traditional treatments (70.4%), and the failure to recognize the situation as being potentially severe (50.6%). Four deaths from complications arising from the snakebite were reported, and three of these were from communities on the banks of the Juruá River. Only one of these received medical assistance. We found an unexpectedly high underreporting of snakebite cases and associated deaths. Snakebite victims utilized three main different healing systems: 1) self-care using miscellaneous techniques; 2) official medical healthcare generally combined with traditional practices; and 3) self-care using traditional practices combined with Western medicines. To mitigate snakebite burden in the Brazilian Amazon, an innovative intervention that would optimize timely delivery of care, including antivenom distribution among existing community healthcare centers, is needed.

Abstract
Water is an essential resource required for various human activities such as drinking, cooking, and other recreational activities. While developed nations have made significant improvement in providing adequate quality water and sanitation devoid of virus contaminations to a significant percentage of the residences, many of the developing countries are still lacking in these regards, leading to many death cases among the vulnerable due to ingestion of virus-contaminated water and other waterborne pathogens. However, the recent global pandemic of COVID-19 seems to have changed the paradigm by reawakening the importance of water quality and sanitation, and focusing more attention on the pervasive effect of the use of virus-contaminated water as it can be a potential driver for the spread of the virus and other waterborne diseases, especially in developing nations that are characterized by low socioeconomic development. Therefore, this review assessed the socioeconomic inequalities related to the usage of virus-contaminated water and other waterborne pathogens in developing countries. The socioeconomic factors attributed to the various waterborne diseases due to the use of virus-contaminated water in many developing countries are poverty, the standard of living, access to health care facilities, age, gender, and level of education. Some mitigation strategies to address the viral contamination of water sources are therefore proposed, while future scope and recommendations on tackling the essential issues related to socioeconomic inequality in developing nations are highlighted.

Abstract
Leptospirosis is a worldwide zoonotic bacterial infection with a rising incidence. French Guiana is mostly covered by Amazonian rain forest. Despite a potentially favorable environment, leptospirosis has been barely studied in French Guiana. The objective of this study was to describe the current trends of leptospirosis epidemiology in French Guiana. A cross-sectional study was performed in the two main hospitals of French Guiana. Cases of leptospirosis from 2007 to 2014 were retrospectively identified with a systematic screening of serological and polymerase chain reaction results to classify them as confirmed, probable, or excluded cases. Medical files were reviewed to collect epidemiological data. Among the 72 included patients, 55 (76.4%) cases were confirmed and 17 (23.6%) were probable. The median age was 39 years (range: 16-82 years) and the M/F sex ratio 6.2. Sixty-two (86.1%) patients required hospitalization, including 12 (16.7%) in the intensive care unit. Three (4.2%) patients died. The monthly distribution of cases was correlated with rainfall (P = 0.004) and moisture (P = 0.038). Professional exposure was frequently identified (especially gold mining and construction). Among 16 different serogroups identified by microagglutination test, Icterohaemorrhagiae was the most frequent (38.0%). This study revealed an epidemiology close to that observed in Brazilian regions, and professional and climatic risk factors. The high diversity of serogroups may reveal a complex environmental reservoir requiring further investigations. Only 20% of leptospirosis patients were suspected as such on hospital admission, thus emphasizing the need to inform local physicians.

Socioenvironmental conditions and intestinal parasitic infections in Brazilian urban slums: a cross-sectional study. Rev Inst Med Trop Sao Paulo 2017; 59:e56. [PMID: 28793024 PMCID: PMC5553943 DOI: 10.1590/s1678-9946201759056] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2017] [Accepted: 03/31/2017] [Indexed: 02/06/2023] Open
Abstract
Methods A cross-sectional study covering an agglomeration of urban slums was conducted between 2015 and 2016 using participants observation, a socioeconomic survey, and the spontaneous sedimentation method with three slides per sample to analyze fresh stool specimens ( n =595) searching for intestinal parasites. Results Endolimax nana ( n =95, 16.0%) and Entamoeba coli ( n =65, 10.9%) were the most frequently identified agents, followed by Giardia intestinalis ( n =24, 4.0%) and Ascaris lumbricoides ( n =11, 1.8%). Coinfections caused by E. nana and E. histolytica/dispar and by Entamoeba coli/A. lumbricoides were significant. The use of piped water as drinking water, the presence of A. lumbricoides , and contamination with coliform bacteria and Escherichia coli were more common in major area (MA) 1. Children (0-19 years) had a greater chance of living in poverty (OR 3.36; 95% CI: 2.50- 4.52; p <0.001) which was pervasive. The predominance of protozoa parasites suggests that a one-size-fits-all approach focusing on preventive chemotherapy for soil-transmitted helminths is not appropriate for all communities in developing countries. It is important that both residents and health professionals consider the socioenvironmental conditions of urban slums when assessing intestinal parasitic infections for disease control and health promotion initiatives.
