“…In contrast, participants without electricity in the home were moderately more likely to have KS (OR=1.9; 95% CI 0.9, 4.5; p=.1028) as did participants who did not sleep under a mosquito net (OR=1.9; 95% CI 1.2, 2.9; p=.006). Although electricity in the home and use of a mosquito net can indicate higher income and education [31,32] higher SES was not associated with KS risk in our study, so use of a mosquito bed net represents some other protective effect. Plasmodium parasitemia has previously been shown to be a risk factor for KSHV infection [28], and a possible association between malaria and development of KS merits further investigation.…”

Background Individuals co-infected with Kaposi’s sarcoma herpesvirus (KSHV) and Human Immunodeficiency Virus (HIV) are at greatly increased risk of developing Kaposi’s sarcoma (KS). The objective of the current analysis is to identify risk cofactors, for KS among HIV-positive individuals. Methods We conducted a case-control study of KS in Cameroon on 161 HIV-positive and 14 HIV-negative cases and 680 HIV-positive and 322 HIV-negative controls. Participants answered a physician-administered questionnaire and provided blood and saliva specimens. Antibodies against KSHV lytic, K8.1, and latent, ORF73, antigens were measured by ELISA to determine KSHV serostatus. Conditional logistic regression was performed to determine multivariate odds ratios (OR) and 95% confidence intervals (CI) for risk factors associated with KS among HIV-positive cases and controls. Results Overall, 98% (158) of HIV-positive cases, 100% (14) of HIV-negative cases, 81% (550) of HIV-positive controls, and 80% (257) of HIV-negative controls were KSHV seropositive. Risk factors for KS among HIV-positive individuals included KSHV seropositivity (OR=9.6; 95% CI 2.9, 31.5), non-use of a mosquito bed net (OR 1.9; 95% CI 1.2, 2.9), minority ethnicity (OR=3.1; 95% CI 1.1, 9.3), treatment from a traditional healer (OR=2.3; 95% CI 1.5, 3.7), history of transfusion (OR=2.4; 95% CI 1.5, 3.9), and family history of cancer (OR=1.9; 95% CI 1.1, 3.1). Conclusion KSHV seroprevalence of ≥80% indicates a high prevalence in the general population in Cameroon. Among HIV-positive individuals, the strong association of KS with non-use of mosquito nets and treatment from traditional healers are compelling findings, consistent with recently reported data from East Africa.

“…Although malaria is endemic throughout Cameroon, the coastal South and Southwest regions have the highest prevalence of malaria in the country [31,35]. Conversely, individuals in higher altitude regions in the North may be more susceptible to KS due to increased exposure to volcanic and iron-rich soils [18,36].…”

“…Most of these children lived in plank houses, which most often have breaks, and crevices on the walls and these allow for easy passage of mosquitoes and consequently higher malaria prevalence. NkuoAkenji et al (23) showed that the prevalence of malaria was significantly higher in children living in plank houses than in those living in cement brick houses. In general, poorer populations which are more often found in rural areas are at greater risk of vector contact and infection, owing to physical proximity to water sources and lowered capacity (lack of education and resources) to use health care services and preventive measures to protect against malaria.…”

“…Malaria transmission is perennial in all regions of Cameroon including the BHD where almost all citizens fall ill with it each year [2]. The National Malaria Control Program (NMCP) report of activities shows that in the South West Region of Cameroon, 56% of consultations, 54% of hospital admissions and 53% of deaths among children below five years are due to malaria [3].…”

Socio-demographic factors influencing the ownership and utilization of insecticide-treated bed nets among malaria vulnerable groups in the Buea Health District, Cameroon

et al. 2014

BackgroundMalaria remains a public health problem and the use of insecticide-treated bed nets (ITNs) against it in vulnerable groups (pregnant women and children <5 years) is recommended in Cameroon. This study was aimed at assessing the socio-demographic factors influencing the ownership and utilization of ITNs among vulnerable groups in the Buea Health District (BHD).MethodsIn a cross-sectional survey a questionnaire was administered in households with at least a child <5 years and/pregnant woman in five health areas of the BHD. Information on demographic variables, household composition, mosquito bed net (MBN) ownership, utilization and factors influencing ownership and utilization was recorded.ResultsA total of 443 respondents were recruited and 208 (47.0%) possessed at least one MBN (total = 275 MBNs) with a median of 1.33 nets. Of the 275 nets found in households, 89 (32%) were potent ITNs and others had never been retreated/treated. Purchase of MBNs from the market was associated with marital status (P = 0.010) and urban settlement (P = 0.045). The number of respondents who did not know where to retreat/treat ITNs was significantly higher (P = 0.005) in urban than rural dwellers. The proportion of rural respondents who had once taken their MBNs for re-treatment was significantly higher (P = 0.002) than that of urban dwellers. MBN utilisation was 69.7% (95% confidence interval; CI = .63.2–75.6%). A total of 83.4%, 13.8% and 3.4% used MBNs throughout the year, during the rainy and dry seasons respectively. MBN use in children under five was associated with being from an urban area (P = 0.01). MBN use in pregnant women was associated with living in block-louver houses than in block-pane houses (P = 0.047).ConclusionsUtilization of MBN needs to be encouraged to match ownership while free distribution of ITNs to vulnerable groups needs to be continuous and consistent.Electronic supplementary materialThe online version of this article (doi:10.1186/1756-0500-7-624) contains supplementary material, which is available to authorized users.
