Nogueira de Brito R, Tanner S, Runk JV, Hoyos J. Looking through the lens of social science approaches: A scoping review of leishmaniases and Chagas disease research. Acta Trop 2024; 249:107059. [PMID: 37918504 DOI: 10.1016/j.actatropica.2023.107059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 10/27/2023] [Accepted: 10/30/2023] [Indexed: 11/04/2023]
Abstract
Scholars have called for increased attention to sociocultural, economic, historical, and political processes shaping Neglected Tropical Diseases (NTDs) ecology. We conducted a scoping review to identify major research themes and the knowledge gaps in social science literature in leishmaniases or Chagas disease (CD). Following the scoping review protocol, we first determined the focus of the review to be centered on identifying research that approaches leishmaniases and CD from social science perspective and was indexed by large, biomedically focused databases. We then searched PubMed and Web of Science using "Leishmaniasis" and "Chagas disease" with "social science" or "anthropology" as search terms. We analyzed 199 articles (123 on leishmaniases and 76 on CD), categorizing them into three main research themes. Sociocultural dimensions of the diseases (leishmaniases=60.2 %; CD=68.4 %) primarily focused on individuals' knowledge, practices, and behaviors, barriers to accessing healthcare (especially in endemic regions), psychosocial effects, stigma, and traditional treatments. Research focused on socioeconomic dimensions of the diseases (leishmaniases=29.3 %; CD=19.7 %) included topics like household characteristics, social capital, and infrastructure access. A final theme, the historical and political contexts of the diseases (Leishmaniases=10.5 %; CD=11.9 %) was less common than other themes. Here, studies consider civil war and the (re)emergence of leishmaniasis, as well as the significance of CD discovery for scientific and public health in Brazil, which is the most common country for research on both leishmaniases and CD that draws on social science approaches. Future directions for research include focusing on how social institutions and economic factors shape diseases education, control measures, healthcare access, and quality of life of people affected by NTDs. Greater attention to social sciences can help mitigate and undo the ways that structural biases have infiltrated biomedicine.

Rocha R, Conceição C, Gonçalves L, Maia C. Knowledge, perceptions and practices of health students and professionals regarding leishmaniasis in Portugal: a cross-sectional study. Parasit Vectors 2023; 16:381. [PMID: 37880779 PMCID: PMC10598964 DOI: 10.1186/s13071-023-05982-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Accepted: 09/24/2023] [Indexed: 10/27/2023] Open
Abstract
BACKGROUND Control of leishmaniasis in the Mediterranean Basin relies on the active contributions from researchers in the fields of animal, human and environmental health. The application of knowledge, perceptions and practices (KPP) questionnaires to health students and professionals in Europe could be fundamental to identify and explore gaps in KPP, highlighting the diversity of conceptions related to this disease between students and professionals active in (One) Health. The objective of this study was to characterize and compare the current knowledge, perceptions and practices regarding leishmaniasis among subgroups of students and health professionals in Portugal through the application of an online questionnaire. METHODS A cross-sectional study targeted the population of health students and professionals in Portugal, including students in medicine, veterinary medicine and environmental health, physicians, veterinarians and environmental health technicians. Potential participants were approached by email via universities and professional societies and organizations and provided with the link to access the online questionnaire. Answers to the self-administered sociodemographic and KPP questionnaire were collected between July and December 2022. Individual KPP scores were calculated by summing grades defined for each question. Logistic regression models were used to search for potential associations, and the results were expressed at estimated crude and adjusted odds ratios with 95% confidence intervals. RESULTS In total, 486 participants were included in this study: 254 students and 232 professionals. Overall, 75% of the participants reported having heard of both human and animal leishmaniasis, and > 80% reported hearing about the disease during their course work (although this was significantly lower among those in the field of environmental health). Around 90% of participants identified the pathogenic agent as a parasite, and an arthropod bite was identified as the main route of transmission by > 95%. Animal leishmaniasis was considered to be diagnosed in Portugal by 87% of participants and human leishmaniasis by only 69%. The main barriers pointed out by professionals to the control of leishmaniasis were: lack of knowledge in the general population, failures in the early diagnosis and treatment of diseased animals, absence/inefficacy of vector control programs and lack of knowledge in human health professionals. Median knowledge and perception scores were higher among professionals in the animal health field and higher in professionals than in students. Median practice scores were not significantly different between groups and subgroups. The multivariate analysis revealed that a longer period of study (for students) and having seen cases of leishmaniasis (for physicians) were associated with above-mentioned median knowledge score. CONCLUSIONS Most health students and professionals are knowledgeable about the cause and transmission route of leishmaniasis. However, recognition of the disease as autochthonous in humans is less common, highlighting the importance of promoting an approach to this infection through a One-Health lens. A national structured plan to control leishmaniasis could overcome some of the barriers pointed out by professionals, namely by implementing systematic phlebotomine surveillance and integrated reporting of animal and human cases of disease.

Entomological Exploration of Sand Flies in Human Communities Affected by Cutaneous and Visceral Leishmaniasis in El Hajeb Province, Morocco. ScientificWorldJournal 2023; 2023:4628625. [PMID: 37151994 PMCID: PMC10159734 DOI: 10.1155/2023/4628625] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Revised: 04/10/2023] [Accepted: 04/11/2023] [Indexed: 05/09/2023] Open
Abstract
Sand flies are the exclusive vectors of leishmaniasis. This group of parasitic diseases is a serious public health problem in Morocco. The aim of this study was to investigate the sand fly fauna, mainly the species composition, biodiversity, and seasonal activity of sand flies in El Hajeb in central Morocco. A total of six stations (Aït Naaman, Aït Rbaa, Aït Brahim, Ain Taoujdate, Sidi Mbarek, and Aït Oufella) were studied, five of which had recently recorded cases of leishmaniasis. Sand fly bimonthly captures were carried out using a sticky paper trap in different biotopes from March to December 2019. A total of 14590 adult sand flies were collected. The activity of the sand fly started in April and declined in November. The periods of high abundance were July, September, and November. Morphological identification of sand flies shows the presence of twelve species: Phlebotomus papatasi, P. longicuspis, P. perniciosus, P. sergenti, P. bergeroti, P. alexandri, P. dreyfussi, P. ariasi, Sergentomyia fallax, S. minuta, S. schwetzi, and S. antennata. The analysis showed that species belonging to the genus Phlebotomus were the most dominant (93.3%) and the risk periods were spread during the summer and autumn seasons. The present study provides for the first time information on the species of sand flies in El Hajeb. It, therefore, provides decision makers with an important tool to conduct vector control actions during peak periods in order to limit the transmission of leishmaniasis. A preprint was made available by the research square in the following link: "https://assets.researchsquare.com/files/rs-1409330/v1/dfef7013-0327-4a54-897f-214924a2d950.pdf?c=1646838874."

Abstract
Human visceral leishmaniasis has long been associated with canine leishmaniasis (CL). However, to date, there is no clear information on the status of the disease in dogs in Morocco that could be used by policymakers for the prevention of human cases. This study aims to assess the status of CL in Morocco and its risk factors through an exhaustive literature search. The meta-analysis was performed using RevMan 5.4. The main results showed that the overall prevalence of CL in Morocco is 17% (95% CI: 0.12-0.22), caused by two strains of Leishmania parasite: Leishmania tropica and L. infantum. According to the region, the maximum prevalence was reported in the coastal provinces and in the central part of the country; while, the CL risk was higher in rural area (18% [95% CI: 0.14-0.23]) and at altitude above 1000 m (23% [95% CI: - 0.08-0.53]). Regarding the intrinsic factors, the prevalence of the disease increased with the age of the dog, (30% [95% CI - 0.09-0.68) and the risk was very high in clinically asymptomatic dogs (RR = 2.08 [95% CI: 1.15-3.76]). This study is the first in Morocco indicating the CL prevalence, its geographical distribution and detailing its risk factors. These results are needed to improve management strategies for the canine reservoir of leishmaniasis in Morocco and interrupt the local transmission cycle to humans.

[PMID: 34389332 DOI: 10.1016/j.actatropica.2021.106090] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2021] [Revised: 07/18/2021] [Accepted: 08/01/2021] [Indexed: 12/13/2022]
Abstract
The investigation of perceptions and behaviors associated with cutaneous leishmaniasis (CL) in different societies has indicated that mere attention to biological and medical aspects is not enough to prevent and control diseases and it is necessary to know the disease-associated behaviors and beliefs. The present study aimed to answer a question: what are the behaviors and perceptions associated with cutaneous leishmaniasis in endemic regions of the world?. This study is a review of the articles published on CL from January 2010 to January 2021, on the International databases Science Direct, Scopus and PubMed. We utilized the terms cutaneous leishmaniasis, in combination with some keywords, including belief, perceptions, knowledge, attitude, practices, prevention, and behavior. Non-original studies, including editorials, reviews, prefaces, brief communications, and letters to the editor, CL epidemiological articles, pre-published articles that has not been peer reviewed, and articles that not provide complete findings on CL-related perceptions and behaviors were excluded from the present paper. After screening, 25 articles from 17 regions of the world were included in the study. The results depicted a novel classification of behaviors and perceptions related to CL prevention and control. Two positive and negative categories of perceptions and behaviors were discovered. Positive perceptions and behaviors were classified into five categories, including: 1- good awareness, 2- perceived susceptibility, 3- perceived severity, 4- perceived response efficiency, and 5- appropriate behaviors. Furthermore, negative perceptions and behaviors were classified into four categories: 1- poor awareness 2- misconceptions (A. About the disease vector B.about the cause of the disease, C. about the consequences of the disease and the treatment process), 3- perceived barriers (A. in prevention, B. in medical treatment), and 4- misbehaviors (A. negligence, B. local and traditional behavioral patterns). In most endemic parts of the world, misconceptions are probably the leading cause of several misbehaviors in dealing with CL. It seems that providing educational programs to strengthen positive beliefs and correct negative beliefs are rooted in the studies in different countries and could be useful for improving the relevant behaviors and ultimately, taking a step towards the prevention and control of CL.

The Cutaneous Leishmaniasis and the Sand Fly: Knowledge and Beliefs of the Population in Central Morocco (El Hajeb). Dermatol Res Pract 2020; 2020:1896210. [PMID: 33281898 PMCID: PMC7688346 DOI: 10.1155/2020/1896210] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2020] [Revised: 11/03/2020] [Accepted: 11/10/2020] [Indexed: 11/18/2022] Open
Abstract
Background Cutaneous leishmaniasis is a neglected parasitic dermal disease transmitted to humans through the bite of an infected female sand fly. Morocco hopes to eliminate all forms of leishmaniasis by 2030. These dermatoses pose a real public health problem in the country. Although the information is available on the disease, individual knowledge of cutaneous leishmaniasis and sand fly is not yet developed. Exploring people's beliefs and popular behaviours about cutaneous leishmaniasis and its vector allows health officials to know the sociocultural aspects of the disease and to improve prevention and control actions. Objectives To identify the knowledge of cutaneous leishmaniasis and its vector in the population in central Morocco. Methods Based on the epidemiological data of leishmaniases in the province of El Hajeb, we conducted a field survey and personal interviews in April and May 2019, among 281 persons belonging to the localities where leishmaniases were registered. Results Our results show that the participants use the concept of "Chniwla" (61.6%) for sand fly and the concept of "Hboub Chniwla" (50.8%) for cutaneous leishmaniasis; 24.6% of the respondents do not know how the disease is transmitted to humans and 43.7% use traditional treatments and home remedies to cure themselves. 44% of participants believe that sand fly does not transmit the disease to humans and only 6.4% were aware of their responsibility in vector control. Conclusions The study concluded that there is a need to simplify the scientific terminology in the health education of citizens regarding these dermatoses and their vector by integrating the popular concepts obtained in this study to raise public awareness and facilitate their involvement as active actors in the prevention of cutaneous leishmaniasis.

Sand Flies Control: A Review of the Knowledge of Health Professionals and the Local Community, Province of El Hajeb, Morocco. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17228448.

Abstract
Sand flies are insect vectors of several diseases including leishmaniases. These vector-borne diseases represent a public health problem in several countries around the world, including Morocco. The objective of this study was to assess simultaneously the knowledge of health professionals and inhabitants on sand flies; a cross-sectional survey was conducted between April and June 2019 among 424 people, 34% of whom were health professionals and 66% of whom were inhabitants of the province of El Hajeb in central Morocco; 46.3% of doctors, 50.7% of nurses, 66.7% of midwives and 69.4% of inhabitants showed a low knowledge of sand flies. Most participants believed that sand flies breed in stagnant and polluted waters. Negative attitudes were found among 72.2% of the inhabitants. Factors associated with a high level of knowledge included continuing education among health professionals and information on vector-borne diseases among residents. The conceptual and cognitive gaps in the knowledge of sand flies reflect the lack of information and training on sand flies. The results of the sand fly knowledge review can be integrated into the national leishmaniases control program and the integrated vector management strategy to raise public awareness on the health risks of sand flies.
