Knowledge, attitude, and adherence to malaria control guidelines and the prevalence of Plasmodium species infection in localities across transmission and ecological zones in Cameroon.

Background: Despite a scale up of control interventions over the years, malaria remains a major public health and economic concern in Cameroon, contributing considerably to hospitalization and deaths. The effectiveness of control strategies depends on the extent of adherence by the population to national guidelines. This study assessed the influence of human knowledge, attitudes, and practices related to malaria and its control on the prevalence of malaria parasite infection, with implications for the elimination of the disease. Methodology: This is a cross-sectional community and hospital-based study, covering the five ecological and three malaria transmission zones in Cameroon. A pre-tested semi-structured questionnaire was used to document socio-demographic and clinical parameters as well as knowledge, attitudes, and practices toward malaria control and management. Consenting participants were screened for malaria parasite with rapid diagnostic test (mRDT) of the peripheral blood. Association between qualitative variables was determined using the chi-square test and logistic regression analysis. Results: A total of 3,360 participants were enrolled, 45.0% (1,513) of whom were mRDT positive, with 14.0% (451/3,216) and 29.6% (951/3,216) having asymptomatic parasitaemia and malaria, respectively. Although most participants knew the cause, symptoms, and control strategies, with 53.6% (1,000/1,867) expertly knowledgeable about malaria overall, only 0.1% (2/1,763) individuals were fully adherent to malaria control measures. Conclusion: The risk of malaria in Cameroon remains high, with the population considerably knowledgeable about the disease but poorly adherent to national malaria control guidelines. Concerted and more effective strategies aimed at improving knowledge about malaria and adherences to control interventions are necessary to ultimately eliminate the disease.

An analysis of social dimensions of podoconiosis and leprosy on affected households in endemic health districts of the North West Region of Cameroon.

Background: Podoconiosis and leprosy are Neglected Tropical Diseases associated with low quality of life, social stigma and isolation of affected people and families. Despite the substantial social burden it imposes, podoconiosis has largely been ignored in the global health literature until recently unlike leprosy. This study assessed and compared the quality of life and social impact of podoconiosis with that of leprosy among affected households and neighborhoods in North West Cameroon. Methods: A comparative cross-sectional design was used. Eighty-six households: 43 podoconiosis and 43 leprosy, plus household neighbours were enrolled from July and August 2015 from three health districts. Podoconiosis patients living in households within Batibo and Ndop health districts were sequentially sampled using a list of confirmed podoconioisis cases from previous studies. Leprosy patients living within communities in Mejang Health Area were sequentially sampled using the Mbingo treatment center register. WHO BREF tool was used to assess quality of life. Franklin Stigma Scale was adapted to assess felt and enacted stigma. Mann-Whitney U test was used to compare differences in stigma and QoL. Results: Physical domain showed a significant difference in the distribution in quality of life between groups (p < 0.05, median:70; U:635, r = 0.2). Overall enacted stigma revealed significant differences with p < 0.05 and r = 0.4. Overall stigma from family members (median:17, U:627 and r = 0.3) and neighbours (median:67, U:336 and r = 0.5) showed significant differences with p < 0.05 in the distribution of scores for both diseases. Sex and age showed significant associations with QoL and stigma. Conclusion: This study reveals the quality of life and stigma associated with podoconiosis on affected households to be comparable to that experienced by households with a leprosy patient. There is need for intensified preventive, management and control schemes to fight podoconiosis in Cameroon, just like leprosy.

A Comparative Analysis of Economic Cost of Podoconiosis and Leprosy on Affected Households in the Northwest Region of Cameroon.

Leprosy and podoconiosis (podo) are neglected tropical diseases that cause severe disfigurement and disability, and may lead to catastrophic health expenditure and hinder economic development of affected persons and households. This study compared economic costs of both diseases on affected households with unaffected neighboring households in the Northwest Region (N.W.R.) of Cameroon. A matched comparative cross-sectional design was used enrolling 170 households (43 podo case households, 41 podo control households, 43 leprosy case households, and 43 leprosy control households) from three health districts in the N.W.R. Direct treatment costs for podo averaged 142 United State dollar (USD), compared with zero for leprosy (P < 0.001). This was also reflected in the proportion of annual household income consumed (0.4 versus 0.0, respectively, P < 0.001). Both diseases caused considerable reductions in working days (leprosy 115 versus podo 135 days. P for comparison < 0.001). The average household income was considerably lower in podo-affected households than unaffected households (410 versus 913 USD, P = 0.01), whereas income of leprosy-affected households was comparable to unaffected households (329 versus 399 USD, P = 0.23). Both leprosy and podo cause financial burdens on affected households, but those on podo-affected families are much greater. These burdens occur through direct treatment costs and reduced ability to work. Improved access to public health interventions for podo including prevention, morbidity management and disability prevention are likely to result in economic returns to affected families. In Cameroon, one approach to this would be through subsidized health insurance for these economically vulnerable households.

Understanding of research, genetics and genetic research in a rapid ethical assessment in north west Cameroon.

BACKGROUND: There is limited assessment of whether research participants in low-income settings are afforded a full understanding of the meaning of medical research. There may also be particular issues with the understanding of genetic research. We used a rapid ethical assessment methodology to explore perceptions surrounding the meaning of research, genetics and genetic research in north west Cameroon. METHODS: Eleven focus group discussions (including 107 adults) and 72 in-depth interviews were conducted with various stakeholders in two health districts in north west Cameroon between February and April 2012. RESULTS: Most participants appreciated the role of research in generating knowledge and identified a difference between research and healthcare but gave varied explanations as to this difference. Most participants' understanding of genetics was limited to concepts of hereditary, with potential benefits limited to the level of the individual or family. Explanations based on supernatural beliefs were identified as a special issue but participants tended not to identify any other special risks with genetic research. CONCLUSION: We demonstrated a variable level of understanding of research, genetics and genetic research, with implications for those carrying out genetic research in this and other low resource settings. Our study highlights the utility of rapid ethical assessment prior to complex or sensitive research.

Perceptions of consent, permission structures and approaches to the community: a rapid ethical assessment performed in North West Cameroon.

BACKGROUND: Understanding local contextual factors is important when conducting international collaborative studies in low-income country settings. Rapid ethical assessment (a brief qualitative intervention designed to map the ethical terrain of a research setting prior to recruitment of participants), has been used in a range of research-naïve settings. We used rapid ethical assessment to explore ethical issues and challenges associated with approaching communities and gaining informed consent in North West Cameroon. METHODS: This qualitative study was carried out in two health districts in the North West Region of Cameroon between February and April 2012. Eleven focus group discussions (with a total of 107 participants) were carried out among adult community members, while 72 in-depth interviews included health workers, non-government organisation staff and local community leaders. Data were collected in English and pidgin, translated where necessary into English, transcribed and coded following themes. RESULTS: Many community members had some understanding of informed consent, probably through exposure to agricultural research in the past. Participants described a centralised permission-giving structure in their communities, though there was evidence of some subversion of these structures by the educated young and by women. Several acceptable routes for approaching the communities were outlined, all including the health centre and the Fon (traditional leader). The importance of time spent in sensitizing the community and explaining information was stressed. CONCLUSIONS: Respondents held relatively sophisticated understanding of consent and were able to outline the structures of permission-giving in the community. Although the structures are unique to these communities, the role of certain trusted groups is common to several other communities in Kenya and Ethiopia explored using similar techniques. The information gained through Rapid Ethical Assessment will form an important guide for future studies in North West Cameroon.
