BackgroundMalaria is a febrile illness caused by protozoan parasites of the genus Plasmodium. It is prevalent in tropical and subtropical countries and becomes a challenge to a highly endemic area of Africa including Ethiopia. The West Armachiho district is a malaria-endemic lowland area where communities are experiencing hyperendemic malaria transmission.ObjectiveThe aim of this study was to determine the prevalence of malaria and the associated risk factors among asymptomatic migrant laborers in the West Armachiho district, Northwest Ethiopia.Materials and methodsCommunity-based cross-sectional study was conducted from September to December 2016 on 385 migrant laborers selected by proportionate two-stage sampling method in Agricultural camps of the West Armachiho district. A standardized questionnaire was used to collect sociodemographic data and risk factors. Capillary blood was collected for Giemsa-stained blood film examination to detect and identify Plasmodium parasites. Data were coded, entered, checked for completeness, and analyzed using SPSS version-20 statistical software. Multivariate logistic regression was used to asses significantly associated risk factors. A P-value <0.05 was considered as statistically significant.ResultsThe prevalence of malaria was found to be 18.4% (n=71). Education level, home area or origin of migrant laborers, number of visits, outdoor sleeping, and bed net utilization were associated with the risk of malaria (P<0.05).ConclusionMalaria was high in this study area and associated with outdoor sleeping, number of visits, home area, and bed net utilization.

Background Food handlers with untrimmed finger nails could contribute or serve as a vehicle for the transmission of food poisoning pathogens. Objectives This study was conducted to determine the prevalence of bacteria and intestinal parasites among food handlers and antibiotic susceptibility profile of the isolated bacteria in Debre Markos University, Ethiopia. Materials and Methods This laboratory-based cross-sectional study involved 220 food handlers working in food service establishments in Debre Markos University between 1st January 2015 to 31th June 2016. Subjects' finger nail specimens of both hands were examined microscopically for intestinal parasites. For bacterial isolation, samples were cultured and bacterial species were identified following standard laboratory procedures. Antimicrobial susceptibility test was performed for all bacterial isolates by using Kirby-Bauer disk diffusion method. Results Of the total 220 subjects examined, 29.5% showed positive culture for different bacterial species from their fingernail contents. Coagulase-negative Staphylococcus was the predominant bacteria species (12.3%) followed by Staphylococcus aureus (5%), E. coli (2.7%), Klebsiella species (2.7%), Enterococcus species (1.8%), Pseudomonas aeruginosa (1.8%), Proteus species (1.4%), Citrobacter species (1.4%), and Serratia species (0.9%). None of the food handlers showed positive culture for Shigella and salmonella and parasites in respect of their finger nail specimens. Isolation of bacteria in finger nail has significant association with finger nail status (P=0.044) and inverse relation with service years (P=0.048). All Staphylococcus aureus and coagulase-negative Staphylococcus species isolates were uniformly susceptible to vancomycin. Only one (9.1%) of Staphylococcus aureus isolates was resistant for methicillin. Conclusion To prevent the food poisoning pathogens, implementation and adherence to infection are the key practices, specially food handlers with long finger nail harbor food debris, microbial contaminations, and allergens.

Background. Standard precautions are infection control techniques against pathogenic microorganisms that are present in human blood and can cause disease in humans. Objective. This study aims to assess knowledge and practice of standard precautions against blood borne pathogens among doctors and nurses in adult emergency room, Addis Ababa, Ethiopia. Methods. Institutional based cross sectional study was conducted from February to March 2018. A total of 128 study participants selected from four public hospitals were enrolled in this study. Data were collected using standardized pretested questionnaire and thencoded, entered, checked for completeness, and analyzed using SPSS version-23 statisticalsoftware. Chi-square test was used to measure the association between variables. P values <0.05 were taken as statistically significant. Result. The mean knowledge score of standard precaution measures was 10.3 out of 14 knowledge items. Out of 32 doctors, 93.8% (n=30) have good knowledge and out of 91 nurses, 86.8% (n=79) have good knowledge. The mean practice level of the study subjects was 8.5 out of 12 practice items. Majority (73.6%) of nurses have good practice level than doctors (21.8%). Knowledge level was significantly associated with the presence of infection control officer, infection control guideline, and washing hands before touching patients. Profession, training, and the presence of infection control guideline in emergency room were significantly associated with practice level of respondents (P<0.05). Conclusion. Both nurses and doctors have good knowledge of standard precaution measures. However, nurses have better practice level than doctors. Orientation during employment and continuous training programs should be provided for the newly employed health workers. In addition sustainable supply systems should be available in each hospital management.

Background Malaria and leishmaniasis are the two largest parasitic killers in the world. Due togeographical overlap of these diseases, malaria-visceral leishmaniasis co-infections occur in large populations and exist in different areas even if they have been poorly investigated. The aim of this study was to determine malaria-visceral leishmaniasis co-infection and their associated factors among migrant laborers. Methods Community based cross-sectional study was conducted from October–December 2016 on migrant laborers who are residents of rural agricultural camp in West Armachiho district and involved in sesame and sorghum harvesting. Standardized questionnaire was used to collect socio-demographic data and risk factors. Capillary blood was collected for giemsa stained blood film examination to detect and identify Plasmodium parasites. Recombinant kinensin (rk39) antigen test was performed to detect anti-leishmania donovani antibody. Data was coded, entered, checked for completeness and analyzed using SPSS version-20 statistical software. Chi-square test was applied to show a significant association between variables. P -value < 0.05 was considered as statistically significant. Results A total of 178 migrant laborers were included in this study. Of these, 74.2% belong to the age group 15–29; 61.2% come from lowland areas and 51.6% visit the area more than four times. Seroprevalence of visceral leishmaniasis was 9.6% (17/178); and 22.4% (40/178) of tested migrant laborers were found malaria infected. The overall prevalence of malaria-visceral leishmaniasis co-infection was 2.8%. Of the total migrant laborer, 47.8% used bed nets, of them 1.2% were malaria-visceral leishmaniasis co-infected; 72.5% used outdoor sites as usual sleeping site, among them 3.1% were malaria-visceral leishmaniasis co-infected; 60.1% were migrants, of which 2.8% were malaria-visceral leishmaniasis co-infected . All variables were not significantly associated with malaria-visceral leishmaniasis co-infection ( P > 0.05). Conclusions Prevalence of malaria-visceral leishmaniasis co-infection was low and it is not significantly associated with residence, number of visits, bed net utilization and outdoor sleeping habit even if both diseases are prevalent in the study area.

Background Visceral leishmaniasis (VL, also called kala-azar) is a public health problem in Ethiopia, especially in sesame and sorghum growing areas. Compared to other populations, labor migrants are the most exposed. Knowing the seroprevalence of Leishmania donovani and associated risk factors is essential to design appropriate control measures. The main aim of this study was to assess the seroprevalence of asymptomatic L. donovani among laborers and associated risk factors in agricultural camps of West Armachiho district, Northwest Ethiopia. Therefore, this study was conducted to know the seroprevalence and associated risk factors of L. donovani infection. Method A cross-sectional study was conducted among 185 laborers from October to December 2017. A simple random sampling technique was used to select study participants from selected agricultural camps. After obtaining written informed consent, data were collected using a structured pretested Amharic version questionnaire using the interview technique. A single finger prick blood sample was collected from the study participants and the blood samples were subjected to the serological diagnostic method using the rk39 kit. The multivariable logistic regression model was used to identify risk factors associated with L. donovani infection. Result Among 185 participants examined using rk39, 14 (7.6%) were seroreactive for L. donovani. Leishmania donovani infection had a statistically significant association with sleeping under Balanites trees (AOR: 4.36, 95%CI: 1.186-16.06), presence of domestic animals near sleeping place (AOR: 4.68, 95% CI: 1.25-17.56), and lack of knowledge about VL transmission (AOR: 3.79, 95% CI: 1.07-13.47). Conclusion Seroprevalence of asymptomatic L. donovani among laborers in agricultural camps of West Armachiho was low. Prevention measures and health education about risk factors that expose to L. donovani infection for the laborers are essential to prevent the spread of the disease.
