Case study of Argus in Togo: An SMS and web-based application to support public health surveillance, results from 2016 to 2019.

INTRODUCTION: Argus is an open source electronic solution to facilitate the reporting and management of public health surveillance data. Its components include an Android-phone application, used by healthcare facilities to report results via SMS; and a central server located at the Ministry of Health, displaying aggregated results on a web platform for intermediate and central levels. This study describes the results of the use of Argus in two regions of Togo. METHODS: Argus was used in 148 healthcare facilities from May 2016 to July 2018, expanding to 185 healthcare facilities from July 2018. Data from week 21 of 2016 to week 12 of 2019 was extracted from the Argus database and analysed. An assessment mission took place in August 2016 to collect users' satisfaction, to estimate the concordance of the received data with the collected data, and to estimate the time required to report data with Argus. RESULTS: Overall completeness of data reporting was 76%, with 80% of reports from a given week being received before Tuesday 9PM. Concordance of data received from Argus and standard paper forms was 99.7%. Median time needed to send a report using Argus was 4 minutes. Overall completeness of data review at district, regional, and central levels were 89%, 68%, and 35% respectively. Implementation cost of Argus was 23 760 USD for 148 facilities. CONCLUSIONS: The use of Argus in Togo enabled healthcare facilities to send weekly reports and alerts through SMS in a user-friendly, reliable and timely manner. Reengagement of surveillance officers at all levels, especially at the central level, enabled a dramatic increase in completeness and timeliness of data report and data review.

Use of surveys to evaluate an integrated oral cholera vaccine campaign in response to a cholera outbreak in Hoima district, Uganda.

OBJECTIVES: To evaluate the quality and coverage of the campaign to distribute oral cholera vaccine (OCV) during a cholera outbreak in Hoima, Uganda to guide future campaigns of cholera vaccine. DESIGN: Survey of communities targeted for vaccination to determine vaccine coverage rates and perceptions of the vaccination campaign, and a separate survey of vaccine staff who carried out the campaign. SETTING: Hoima district, Uganda. PARTICIPANTS: Representative clusters of households residing in the communities targeted for vaccination and staff members who conducted the vaccine campaign. RESULTS: Among 209 households (1274 individuals) included in the coverage survey, 1193 (94%; 95% CI 92% to 95%) reported receiving at least one OCV dose and 998 (78%; 95% CI 76% to 81%) reported receiving two doses. Among vaccinated individuals, minor complaints were reported by 71 persons (5.6%). Individuals with 'some' education (primary school or above) were more knowledgeable regarding the required OCV doses compared with non-educated (p=0.03). Factors negatively associated with campaign implementation included community sensitisation time, staff payment and problems with field transport. Although the campaign was carried out quickly, the outbreak was over before the campaign started. Most staff involved in the campaign (93%) were knowledgeable about cholera control; however, 29% did not clearly understand how to detect and manage adverse events following immunisation. CONCLUSION: The campaign achieved high OCV coverage, but the surveys provided insights for improvement. To achieve high vaccine coverage, more effort is needed for community sensitisation, and additional resources for staff transportation and timely payment for campaign staff is required. Pretest and post-test assessment of staff training can identify and address knowledge and skill gaps.

Oral cholera vaccination in hard-to-reach communities, Lake Chilwa, Malawi.

OBJECTIVE: To evaluate vaccination coverage, identify reasons for non-vaccination and assess satisfaction with two innovative strategies for distributing second doses in an oral cholera vaccine campaign in 2016 in Lake Chilwa, Malawi, in response to a cholera outbreak. METHODS: We performed a two-stage cluster survey. The population interviewed was divided in three strata according to the second-dose vaccine distribution strategy: (i) a standard strategy in 1477 individuals (68 clusters of 5 households) on the lake shores; (ii) a simplified cold-chain strategy in 1153 individuals (59 clusters of 5 households) on islands in the lake; and (iii) an out-of-cold-chain strategy in 295 fishermen (46 clusters of 5 to 15 fishermen) in floating homes, called zimboweras. FINDING: Vaccination coverage with at least one dose was 79.5% (1153/1451) on the lake shores, 99.3% (1098/1106) on the islands and 84.7% (200/236) on zimboweras. Coverage with two doses was 53.0% (769/1451), 91.1% (1010/1106) and 78.8% (186/236), in the three strata, respectively. The most common reason for non-vaccination was absence from home during the campaign. Most interviewees liked the novel distribution strategies. CONCLUSION: Vaccination coverage on the shores of Lake Chilwa was moderately high and the innovative distribution strategies tailored to people living on the lake provided adequate coverage, even among hard-to-reach communities. Community engagement and simplified delivery procedures were critical for success. Off-label, out-of-cold-chain administration of oral cholera vaccine should be considered as an effective strategy for achieving high coverage in hard-to-reach communities. Nevertheless, coverage and effectiveness must be monitored over the short and long term.

Oral cholera vaccine coverage during a preventive door-to-door mass vaccination campaign in Nampula, Mozambique.

BACKGROUND: In addition to improving water, sanitation and hygiene (WASH) measures and optimal case management, the introduction of Oral cholera vaccine (OCV) is a complementary strategy for cholera prevention and control for vulnerable population groups. In October 2016, the Mozambique Ministry of Health implemented a mass vaccination campaign using a two-dose regimen of the Shanchol™ OCV in six high-risk neighborhoods of Nampula city, in Northern Mozambique. Overall 193,403 people were targeted by the campaign, which used a door-to-door strategy. During campaign follow-up, a population survey was conducted to assess: (1) OCV coverage; (2) frequency of adverse events following immunization; (3) vaccine acceptability and (4) reasons for non-vaccination. METHODOLOGY/PRINCIPAL FINDINGS: In the absence of a household listing and clear administrative neighborhood delimitations, we used geospatial technology to select households from satellite images and used the support of community leaders. One person per household was randomly selected for interview. In total, 636 individuals were enrolled in the survey. The overall vaccination coverage with at least one dose (including card and oral reporting) was 69.5% (95%CI: 51.2-88.2) and the two-dose coverage was 51.2% (95%CI: 37.9-64.3). The campaign was well accepted. Among the 185 non-vaccinated individuals, 83 (44.6%) did not take the vaccine because they were absent when the vaccination team visited their houses. Among the 451 vaccinated individuals, 47 (10%) reported minor and non-specific complaints, and 78 (17.3%) mentioned they did not receive any information before the campaign. CONCLUSIONS/SIGNIFICANCE: In spite of overall coverage being slightly lower than expected, the use of a mobile door-to-door strategy remains a viable option even in densely-populated urban settings. Our results suggest that campaigns can be successfully implemented and well accepted in Mozambique in non-emergency contexts in order to prevent cholera outbreaks. These findings are encouraging and complement the previous Mozambican experience related to OCV.

Innovative vaccine delivery strategies in response to a cholera outbreak in the challenging context of Lake Chilwa. A rapid qualitative assessment.

A reactive campaign using two doses of Shanchol Oral Cholera Vaccine (OCV) was implemented in 2016 in the Lake Chilwa Region (Malawi) targeting fish dependent communities. Three strategies for the second vaccine dose delivery (including delivery by a community leader and self-administration) were used to facilitate vaccine access. This assessment collected vaccine perceptions and opinions about the OCV campaign of 313 study participants, including: fishermen, fish traders, farmers, community leaders, and one health and one NGO officer. Socio-demographic surveys were conducted, In Depth Interviews and Focus Group Discussions were conducted before and during the campaign. Some fishermen perceived the traditional delivery strategy as reliable but less practical. Delivery by traditional leaders was acceptable for some participants while others worried about traditional leaders not being trained to deliver vaccines or beneficiaries taking doses on their own. A slight majority of beneficiaries considered the self-administration strategy practical while some beneficiaries worried about storing vials outside of the cold chain or losing vials. During the campaign, a majority of participants preferred receiving oral vaccines instead of injections given ease of intake and lack of pain. OCV was perceived as efficacious and safe. However, a lack of information on how sero-protection may be delayed and the degree of sero-protection led to loss of trust in vaccine potency among some participants who witnessed cholera cases among vaccinated individuals. OCV campaign implementation requires accompanying communication on protective levels, less than 100% vaccine efficacy, delays in onset of sero-protection, and out of cold chain storage.

Epilepsy-associated stigma in Bolivia: a community-based study among the Guarani population: an International League Against Epilepsy/International Bureau for Epilepsy/World Health Organization Global Campaign Against Epilepsy Regional Project.

Epilepsy is associated with a significant burden of social stigma that appears to be influenced by psychosocial and cultural factors. Stigma has a negative effect on the management of people with epilepsy (PWE), representing one of the major factors that contribute to the burden of epilepsy. To assess stigma perception among the Guarani population, one hundred thirty-two people living in Guaraní communities in Bolivia were invited to complete the Stigma Scale of Epilepsy questionnaire. The main determinants of stigma identified were: the fear linked to loss of control, the feelings of sadness and pity toward PWE, the difficulties faced by PWE in the professional and relationship fields, the level of education and type of seizure. Our study pointed out that, in this population, PWE face difficulties in everyday life because of epilepsy-associated stigma and the results attest to the importance of promoting community-based educational programs aimed at reducing the stigmatization process.

Investigating epilepsy in Africa: 10 years of data collection using a standardized questionnaire in 2,269 peoples with epilepsy.

PURPOSE: The need for comparable epidemiologic data on epilepsy from various locations in tropical areas has led in 1994 to the creation of a questionnaire able to standardize information. The Limoges' questionnaire was created to collect information independently of the objectives of each survey performed, and since it has been employed in various continents under tropics latitude. In Africa between 1994 and 2004, 13 epidemiologic surveys in 12 countries were performed by this means. Authors of these works were solicited to communicate their raw data on people with epilepsy (PWE). METHODS: Information collected was aggregated in a database upon which operations of data management were processed. Undernutrition status was determined using an anthropologic method, according World Health Organization (WHO) recommendations. Factors associated with undernutrition and absence of treatment by phenobarbitone were searched for by using multivariate logistic regression. KEY FINDINGS: Information about 2,269 PWE was collected. Mean treatment gap and undernutrition were determined, respectively, to be 30.6% [95% confidence interval (95% CI) 28.7-32.6] and 25.4% (95% CI 22.7-28.2). Factors significantly associated with undernutrition and not being treated with phenobarbitone were determined. SIGNIFICANCE: Despite the different purposes of each study, we were able to pool information in order to characterize and study particular traits of PWE in Africa. Some items of particular importance should be collected systematically and will be highlighted in a newer version of this questionnaire. Because many surveys were undertaken using this tool in tropical areas, a backward compatibility should be ensured.

Sociocultural dimension of epilepsy: an anthropological study among Guaraní communities in Bolivia--an International League Against Epilepsy/International Bureau for Epilepsy/World Health Organization Global Campaign against Epilepsy regional project.

This study was performed to analyze sociocultural beliefs about epilepsy among Guaraní communities in Bolivia. People with epilepsy, their family members, the general population, and local health care personnel were interviewed about the meaning of and beliefs, feelings, and practices concerning epilepsy. Epilepsy is called mano-mano, a term that means being in a constant passage between life and death. The disease is attributed mainly to a failure to observe a fasting period and to other eating habits. Natural remedies are the most recommended treatments even though half of respondents reported that antiepileptic drugs may be effective. The concept of epilepsy as an embodied disease with natural causes appears to differ from that documented in other traditional societies. People with epilepsy do not represent a threat to the community, which seems to have an attitude aimed at their protection. Moreover, people from these communities appear to favor a combination of biomedical and traditional care systems.

Sociocultural and psychological features of perceived stigma reported by people with epilepsy in Benin.

PURPOSE: Stigma is a major burden of epilepsy. In sub-Saharan Africa the few studies that addressed epilepsy stigma emphasize enacted, rather than perceived, stigma. This inattention may compromise clinical management and delay help seeking, thereby contributing to the treatment gap. We assessed perceived stigma and identified sociocultural and psychological factors explaining greater stigma among people with epilepsy (PWE) in Benin. METHODS: PWE included in this study were ascertained using a door-to-door survey in the general population in a Beninese rural area. We applied both qualitative and quantitative research methods to assess stigma and patient's experience and beliefs. An Explanatory Model Interview Catalogue (EMIC) and verbally administered questionnaires provided data for demographic, clinical, and sociocultural features. Sociocultural features were evaluated in terms of illness-related experience and sociocultural representations of epilepsy. Depression and anxiety were also screened. RESULTS: Eighty PWE were included. About 68.7% reported feeling stigmatized. Multivariate regression revealed that factors independently associated with perceived stigma were experience of social isolation (p < 0.001), experience of marital problems (p < 0.01), and presence of anxiety disorder (p < 0.01). DISCUSSION: Perceived stigma is an important issue in epilepsy in Benin. Social factors seem to be more influential than sociocultural representation of epilepsy. Insofar as research is needed in other African countries to determine the nature and relevant features of stigma to improve treatment and control.

Knowledge of epilepsy in the general population based on two French cities: implications for stigma.

The objective of this study was to assess the knowledge and attitudes of people living in two French counties. The data were collected from 1777 adults in the general population who were interviewed. Knowledge of and attitudes toward epilepsy in these French samples proved largely favorable: 90.6% identified epilepsy as different from a mental disorder or lunacy, and 79.2% correctly identified epilepsy as a brain disorder. The majority agreed with the statements that people with epilepsy should have the opportunity to get married and that children with epilepsy should be allowed to go to school with others. However, gaps in knowledge and erroneous beliefs prevailed, notably among men, old people, and individuals with low levels of education. This study yielded encouraging results. However, further studies are needed to confirm these findings and gain a better understanding of the contribution of French public knowledge to the causative factors generating stigma in France.
