Schistosomiasis knowledge, attitude, practices, and associated factors among primary school children in the Siphofaneni area in the Lowveld of Swaziland.

BACKGROUND: Schistosomiasis, a worldwide concern, has received attention in Swaziland through control programs such as deworming programs, education programs, and school health programs; however, these programs neglect the importance of monitoring and evaluation strategies such as assessing children's knowledge, attitudes and practices (KAPs) and the prevalence of the disease. Children are a high-risk group because of their water contact practices, and need to be informed about schistosomiasis to influence their attitudes and practices. Social and cultural factors are involved in schistosomiasis control because they instill myths and misconceptions about the disease. As a result, children in the community may be comfortable with bad practices. This study aimed to assess the KAPs of schoolchildren on schistosomiasis, and to identify practices that support or hinder the progress of schistosomiasis control. METHODS: In 2014, a descriptive quantitative cross-sectional survey was conducted through questionnaires among Siphofaneni primary schools, an area hit by schistosomiasis in the Lowveld of Swaziland. A logistic regression model was applied to analyze the data. RESULTS: Moderate knowledge, good attitudes, and fairly good practices were observed in the children. However, practices of certain children were risky and they still had some misconceptions. Knowledge was correlated with practice and with predictors of good and bad practices such as male sex, always urinating in water, and always using river water for domestic practices. CONCLUSION: This study suggests that empowering children with knowledge and attempting to modify their water contact, and improved human waste disposal practices are necessary for schistosomiasis control.

Knowledge of human social and behavioral factors essential for the success of community malaria control intervention programs: The case of Lomahasha in Swaziland.

BACKGROUND: Although malaria control programs have made rapid progress recently, they neglect important social and behavioral factors associated with the disease. Social, political, and cultural factors are involved in malaria control, and individuals in a community may be comfortable in behaving in ways that, to an outsider, may seem contrary to commonly held perceptions. Malaria control efforts can no longer afford to overlook the multidimensional human contexts that create and support varying notions of malaria and its prevention, treatment, and control. This study aimed to assess the knowledge and perceptions of malaria issues in the community, and to identify practices that support or hinder the progress of malaria control programs. METHODS: A triangulation study involving individual interviews, focus group discussions, and observatory analysis between 2003 and 2010 at Lomahasha, a malarious community on the eastern border of Swaziland and Mozambique, was conducted. RESULTS: Results indicated that a high knowledge level and good perception of the disease were observed in the age group of < 40 years, contrary to those in higher age groups, among the Lomahasha community members. However, behavior of certain community groups includes practices that are not supportive of the national control program's aspirations, such as delay in seeking medical attention, staying outdoors until late, maintaining stagnant water in roadside excavations, and seeking medical assistance from wrong sources. Malpractices are more commonly observed among men, boys, and those who drink alcohol. CONCLUSION: This study suggests a thorough community diagnosis before all intervention programs for malaria control are instituted.

Needs assessment survey for Master's of Science training in environmental health science in Swaziland.

A needs assessment survey research was carried out for Master's of Science training in environmental health in Swaziland. The objective of the survey was to acquire information on training needs, gaps, options of specializations, program structure, courses, topics, and research areas that are relevant to the needs of the stakeholders and sector organizations related to environmental health. A document study, focus group discussion with key informants, stakeholder forum workshop, and needs assessment questionnaire to the wider stakeholders were used for the study described here. The findings of the authors' study point to a shortage of qualified personnel in environmental health; lack of capacity in strategy planning and project management; and lack of capacity in research, data collection, and environmental monitoring skills, among other things. A program structure that takes into account the multidisciplinary nature of environmental health with provisions for specialization was favored. Suggestions on course content, mode of delivery, and research topics to be addressed were also given.

Markers of anti-malarial drug resistance in Plasmodium falciparum isolates from Swaziland: identification of pfmdr1-86F in natural parasite isolates.

BACKGROUND: The development of Plasmodium falciparum resistance to chloroquine (CQ) has limited its use in many malaria endemic areas of the world. However, despite recent drug policy changes to adopt the more effective artemisinin-based combination (ACT) in Africa and in the Southern African region, in 2007 Swaziland still relied on CQ as first-line anti-malarial drug. METHODS: Parasite DNA was amplified from P. falciparum isolates from Swaziland collected in 1999 (thick smear blood slides) and 2007 (filter paper blood spots). Markers of CQ and sulphadoxine-pyrimethamine (SP) resistance were identified by probe-based qPCR and DNA sequencing. RESULTS: Retrospective microscopy, confirmed by PCR amplification, found that only six of 252 patients treated for uncomplicated malaria in 2007 carried detectable P. falciparum. The pfcrt haplotype 72C/73V/74I/75E/76T occurred at a prevalence of 70% (n = 64) in 1999 and 83% (n = 6) in 2007. Prevalence of the pfmdr1-86N allele was 24% in 1999 and 67% in 2007. A novel substitution of phenylalanine for asparagine at codon 86 of pfmdr1 (N86F) occurred in two of 51 isolates successfully amplified from 1999. The pfmdr1-1246Y allele was common in 1999, with a prevalence of 49%, but was absent among isolates collected in 2007. The 86N/184F/1246D pfmdr1 haplotype, associated with enhanced parasite survival in patients treated with artemether-lumefantrine, comprised 8% of 1999 isolates, and 67% among 2007 isolates. The pfdhfr triple-mutant 16C/51I/59R/108N/164I haplotype associated with pyrimethamine resistance was common in both 1999 (82%, n = 34) and 2007 (50%, n = 6), as was the wild-type 431I/436S/437A/540K/581A/613A haplotype of pfdhps (100% and 93% respectively in 1999 and 2007). The quintuple-mutant haplotype pfdhfr/pfdhps-CIRNI/ISGEAA, associated with high-level resistance to SP, was rare (9%) among 1999 isolates and absent among 2007 isolates. CONCLUSIONS: The prevalence of pfcrt and pfmdr1 alleles reported in this study is consistent with a parasite population under sustained CQ drug pressure. The low prevalence of dhps-437G and dhps-540E mutations (ISGEAA) and the rarity of quintuple-mutant haplotype pfdhfr/pfdhps-CIRNI/ISGEAA suggest that SP retains some efficacy in Swaziland. Anti-malarial policy changes in neighbouring countries may have had an impact on the prevalence of molecular markers of anti-malarial resistance in Swaziland, and it is hoped that this new information will add to understanding of the regional anti-malarial resistance map.
