Aims: Determine factors associated with malaria infection, the prevalence of asymptomatic carriage of malaria parasites and fevers of non malarial origin. Study Design: This was a cross-sectional study.

Malaria remains a major health problem in Cameroon; It accounts for 38% of consultations, 24% of deaths and 36.8% of absenteeism in the country. The negative economic impact of malaria has encouraged a new control approach targeting companies. In this regard, a cross sectional study was conducted from February 2015 to June 2017 in 14 companies in the town of Douala. This study aimed at determining the prevalence, control practices of employees and identifying associated factors with malaria. A total of 2705 workers were interviewed and systematically screened for malaria using LED fluorescence microscopy (CyScope®). All positive cases were given a malaria treatment. The prevalence of malaria and asymptomatic malaria was 30.1% and 28.9% respectively; asymptomatic malaria accounted for 95.7% of all positive diagnostic test. Malaria infection was significantly higher in employees aged 36–60 years (30.5%) and having completed primary studies (36%). ITNs ownership and utilization were 86.36% and 77.23% respectively. The risk for malaria infection has significantly decreased with age and educational level while the employees’ level of education and size of households were significantly associated with the regular utilization of ITNs. This is the first study assessing malaria prevalence and risk factors in workplace in Cameroon and using a novel diagnostic tool. This study outlines a high prevalence of malaria infection, especially asymptomatic carriage, high rates of ITNs ownership and utilization, as well as the influence of level of education, age and household size as associated factors. Active case detection of asymptomatic carriers through systematic screening of employees at workplace and their treatment is feasible with the Cyscope microscope and could be a good complement to ongoing control strategies.

Introduction: HIV causes progressive impairment of the cellular immune system leading to increased susceptibility to infectious agents. Parasitic infestations are common in HIV-infected patients and usually lead to diarrhoea. Few studies have addressed the issue of intestinal parasites among HIV-infected persons in Cameroon. This investigation was conducted in Douala, Cameroon, to assess the prevalence of gastrointestinal parasites in HIV-infected patients, taking into account their immune status and treatment course. Methodology: Stool and blood samples were collected from 201 HIV-positive patients for the investigation of intestinal pathogens and CD4

Introduction: Schistosomiasis is a neglected tropical disease with endemic foci in Cameroon. Epidemiological data on schistosomiasis in pregnancy are scarce in the country. This study describes the prevalence, diversity and factors associated with schistosomiasis in pregnant women in Njombe-Penja where schistosomiasis was first reported in 1968. Methodology: Two hundred and eighty-two (282) pregnant women were enrolled at first antenatal consultation between April and December 2016. A questionnaire was used to document socio-economic and obstetric information. Stool and terminal urine samples were collected and analysed using Kato-Katz/Formol-Ether concentration techniques and centrifugation methods respectively. Haemoglobin concentration was measured from finger prick blood, using an URIT®-12 electronic haemoglobinometer. Bivariate and logistic regression were used for statistical analyses with Epi-Info version 7.2.1.0. Statistical significance level was set at 0.05. Results: The overall prevalence of schistosomiasis was 31.91%. Schistosoma guineensis, S. haematobium and S. mansoni infections were found in 0.35% (n = 1), 4.96% (n = 14) and 28.01% (n = 79) of participants, respectively. Co-infection with two species of Schistosoma was found in 4.44% of these women. The prevalence of this disease was significantly higher in younger women (≤ 20 years old) and among residents of Njombe. All S. haematobium infected women were anemic and infection was associated with significantly lower haemoglobin levels (p = 0.02). Conclusion: The prevalence of schistosomiasis is high among pregnant women in Njombe-Penja, with some adverse effects on blood levels. Three Schistosoma species were found. Female of childbearing age should be considered for mass drug administration.
