USAGE OF A RAPID DIAGNOSTIC TEST FOR MALARIA IN CHILDREN
Background: Malaria is still the primary cause of pediatric deaths. The efficient management of pediatric malaria
requires its rapid and accurate diagnosis. To fulfill this requirement, rapid diagnostic tests have been developed, but
their evaluation before commercialization is never exhaustive. The aim of this study was to evaluate the performance of
a rapid diagnostic test (SD Bioline Malaria Antigen P.f/Pan) to diagnose malaria in children.
Materials and Methods: Testing was conducted on children aged between 6 months and 15 years who were examined
at the CME-FCB as a result of fever. Enrollment took place from April to October 2014. All children presenting with
fever were sampled (3ml of blood). These blood samples were tested for malaria using microscopy on a thick blood
smear and by a rapid diagnostic test (RDT) SD Bioline Malariae Antigen P.f/Pan.
Results: A total of 249 children were enrolled in this study. Malaria presence as determined by microscopy and by
RDT was 30.9% and 58.2% respectively. The sensitivity, specificity, positive and negative predictive values compared
to microscopy were: 75; 48.8; 39, and 81.6%. With these performances, the malaria SD Bioline rapid test presents
lower values compared to WHO recommendations for rapid tests (sensitivity > 95%) in children.
Conclusion: SD Bioline Malaria Antigen P.f/Pan test should only be used in peripheral health structures that lack
resources, and should be aided by clinical diagnosis
Maternal Socio-Demographic Factors and Mother-to-Child Transmission of HIV in the North Region of Cameroon
Background and Objective: Socio-demographic factors are important risk factors for HIV infection. Maternal socio-demographic factors associated with HIV transmission from mother to child are not well elucidated to our knowledge. This study aimed to assess the maternal socio-demographic factors associated with HIV vertical transmission.
Methods: A matched case-control study was conducted among children under 15 years of age born to HIV-infected mothers; using a structured questionnaire. The study was conducted in four health facilities in the North Region of Cameroon from July 2015 to October 2016. HIV- infected children were the cases, and HIV-uninfected children were the controls. One case was matched to nearly 4 controls according to age and sex. A total of 113 HIV-infected mothers of children under 15 years of age were purposively enrolled in the study. A questionnaire was administered to mothers and socio-demographic characteristics were collected. Blood samples were collected from the mother and her child for the determination or confirmation of HIV status. Univariate and multiple logistic regressions were used to assess associations between socio-demographic variables and HIV transmission from mother to child.
Results: A total of 113 HIV-infected mothers and 113 children under 15 years of age were enrolled in this study. The majority of the mothers were between the age ranges of 25 years to 34 years. Of the 113 HIV-infected mothers, 69 (61%) were Muslims, 33 (32.1%) were not educated, 88 (77.8%) were unemployed, 80 (70.9%) were married, out of which 49 (61.6%) were engaged in a monogamous union. Of the 113 children (49.6%) were female, 25 (22.1%) were HIV-infected and 88 (77.9%) were HIV-exposed uninfected. At the univariate level, mothers who achieved a primary level of education were less likely to transmit HIV to infants compared to uneducated mothers [OR=0.28; CI (0.08-0.95); p=0.04]; and widows had a higher likelihood of HIV transmission to infants compared to married mothers [OR=4.65; CI (1.26-17.20); p=0.02]. Using multiple logistic regression, the maternal primary education level [aOR=0.32; CI (0.08-0.90); p=0.03] and widowerhood [aOR=7.05; CI (1.49-33.24); p=0.01] remained highly associated with the likelihood of HIV transmission to infants.
Conclusion and Global Health Implications: Uneducated mothers and widows had a higher likelihood of mother-to-child transmission of HIV. Our findings should prompt reinforcement of prevention strategies targeting uneducated women and widows.

Mapping and size estimates of female sex workers in Cameroon: Toward informed policy for design and implementation in the national HIV program.
BackgroundDue to high HIV prevalence among Female Sex Workers (FSWs) in Cameroon (36.5%), this population is especially vulnerable to HIV acquisition and transmission nationwide. Though being prioritized in the national HIV response, it would be relevant to generate statistics on the number of FSWs in order to guide HIV interventions among FSWs. Our objective was to estimate the size of FSWs within hotspots of Cameroon.MethodsA cross-sectional study was conducted from September-November 2015 in selected cities in Cameroon: Bafoussam, Bamenda, Bertoua, Buea, Douala, Kribi, Limbé, and Yaoundé. A programmatic mapping was used, consisting of interviews with secondary key informants (KI) to identify hotspots of FSWs and their respective estimated numbers. Validation of size estimates was done by interviews with FSW at each hotspot. Size estimations in the councils mapped were extended to others not mapped using a Poisson regression model.ResultsA total of 2,194 hotspots were identified: Douala (760), Yaoundé (622), Bamenda (263), Bafoussam (194), Kribi (154), Bertoua (140), Limbé (35), and Buea (26). The estimated total number (range) of FSWs was 21,124 (16,079-26,170), distributed per city as follows: Douala 7,557 (5,550-9,364), Yaoundé 6,596 (4,712-8,480), Bafoussam 2,458 (1,994-2,923), Bamenda 1,975 (1,605-2,345), Kribi 1,121 (832-1,408), Bertoua 1,044 (891-1,198), Buea 225 (185-266), and Limbé 148 (110-148). The variability of estimates among cities was also observed within the councils of each city. The national predicted estimate of FSW population was 112,580 (103,436-121,723), covering all councils of Cameroon. An estimate of 1.91% (112,580/5,881,526; 0.47%-3.36%) adult female population in Cameroon could be sex workers.ConclusionThere are considerable numbers of FSW in major cities in Cameroon. There is a need to prioritize interventions for HIV prevention toward this population in order to limit the burden of HIV sexual transmission nationwide
