Seroprevalence of and risk factors for Q fever in dairy and slaughterhouse cattle of Jimma town, South Western Ethiopia.

ABSTRACT:

Background

Q fever is a zoonotic disease, caused by Gram negative bacterium C. burnetii, which imparts significant socio-economic burden due to production and reproductive loss (abortion, stillbirth, and infertility) in ruminants and debilitating clinical disease in human populations. While sheep and goats are considered the primary reservoirs of infection to humans, infection can also result from exposure to cattle. Recent studies indicate that in Ethiopia Q fever is a disease of growing public health interest. The top cattle producing region in Ethiopia is the Oromia region and Jimma is the zone that ranks first in the population of cattle within Oromia. While in Jimma zone livestock production plays an important role in people's livelihoods and nutrition, to date, there is no available report on seroprevalence of Q fever in cattle. This is particularly important due to the low dairy farm biosecurity in Jimma town. This study aimed to evaluate the potential risk for public health from cattle production; a specific objective of this study included the estimation of the seroprevalence of C. burnetii infection and its potential risk factors in dairy cattle and cattle for slaughter in Jimma Town.

Results

The seroprevalence of C. burnetii in cattle present at dairy farms was significantly lower compared to cattle presented at slaughterhouse [6.17% (95% CI: 3.41-10.13) and 11.79% (95% CI: 7.63-17.17), respectively; (P?=?0.04)]. As the age of dairy cattle increase by 1 year, they were 1.51 more likely to be positive of C. burnetii [OR?=?1.51 (95%CI: 1.30-1.75; (P?=?0.000)]. Cattle managed in semi-intensive production systems were 8.08 more likely to be C. burnetii seropositive compared to intensively managed dairy cattle [OR?=?8.08 (95%CI: 1.03-63.68); P?=?0.047]. Dairy cattle with access to nuisance animals like dogs, cats and mice were 5.65 more likely to be C. burnetii seropositive compared to dairy cattle without access to these animals. On the other hand, dairy cattle that have no tick infestation are 93% less likely to be seropositive for C. burnetii [OR?=?0.07 (95%CI: 0.01-0.74); P?=?0.027]. Concerning farm-level data, farms of larger herd sizes were 1.03 more likely to be C. burnetii seropositive than small herd farms [OR?=?1.03 (95%CI: 0.99-1.06)]. The result from slaughterhouse indicates that as the age of cattle increase by 1 year their chance of being C. burnetii seropositive increases by 2.27 [OR?=?2.27 (95%CI: 1.93-2.68); p?=?0.000].

Conclusion

Considering its zoonotic and economic burden the seroprevalence of Q fever recorded in this study is of eminent public health concern with a farm-level and slaughterhouse seroprevalence of 6.17 and 11.79% respectively. Based on modifiable risk factors identified in this study, Q fever management plans better be focused on health education and awareness campaigns for abattoir workers and dairy farm workers. Dairy farm Q fever management plans should contemplate improved dairy herd biosecurity with regards to cattle tick infestation, keeping different livestock species segregated and avoiding mixing of herd with others with unknown health status.

Project description:BackgroundCorona (COVID-19) is an infectious disease caused by a newly discovered corona virus. The World Health Organization has recommended several preventive measures for COVID-19 and African countries, including Ethiopia had accepted and engaged in the recommended preventive measures. Adherence to COVID-19 prevention measure is still a big problem; however, the level of adherence to preventive measures had not reported in Ethiopia among students and there is an information gap, therefore, this study conducted to fill the information gap on level of adherence to COVID-19 preventive measures among students.ObjectiveThis study aimed to assess the level of adherence to COVID-19 preventive measures and its associated factors among high school students in Jimma Town public High Schools in southwest Ethiopia, 2021.Methods sand materialsAn institution-based cross-sectional study was conducted among 404 systematically selected high school students from Jimma town from July 15 to August 2, 2021. The sample size was determined using a single-population proportion formula, and data were collected through face-to-face interviews using a structured and pretested questionnaire. Data were entered into Epi-data manager 4.4.2.1 then exported to Stata 14 for cleaning and analysis. Bivariate and multivariable ordinal logistic regression analyses were declared to identify significant variables. Finally; significant factors were determined at a significance level of <0.05.ResultsOf 388 students included in the analysis, approximately 14.7% (95%CI: 11.51-18.60) of students had good level of adherence to COVID-19 preventive measures.Only 6.9%of participants had good knowledge where as approximately half of the respondents had favorable attitude toward COVID-19 preventive measures. Factors such as Female gender (AOR = 1.03(95%CI: 1.01-1.74), access to water and soap (AOR = 2.11(95%CI: 1.06-4.19) andattitude (AOR = 4.36(95%CI: 2.69-7.08)) were found to have a statistically significant association with level of adherence to COVID-19 preventive measures.ConclusionAdherence to COVID-19preventive measures among students wasunexpectedly lower than in other studies. Female gender, lack of access to water and soap, and attitudes were factors associated with adherence to COVID-19 preventive measures. Therefore, to ensure maximal adherence to preventive measures for COVID-19, special messages and efforts targeting males, increasing access to water and soap, trainingto improve attitude toward COVID-19 preventive measures should be implemented at schools.

Project description:BackgroundLarge-scale deworming programs have been successful in reducing the burden of disease due to soil-transmitted helminth (STH; Ascaris lumbricloides, Trichuris trichiura and hookworm) infections, but re-infection in absence of other measures is unavoidable. We assessed the role of nail contamination as a source of infection with the goal to evaluate the potential of nail clipping as a simple measure to further reduce STH-attributable morbidity.MethodsA cross-sectional study was conducted in Jimma Town (Ethiopia). Both stool samples and clipped nails were collected from 600 schoolchildren and microscopically screened for the presence of STHs. We also interviewed the children to gain insights into their hygiene practices. Subsequently, we explored any associations between infection, nail contamination and personal hygiene.ResultsAny STH infections were observed in 24.3% of the children (A. lumbricoides: 18.5%; T. trichiura: 9.8%; hookworm: 0.5%). The intensity of the infections was mainly low, only in a few cases a moderate-to-heavy intensity infection was observed (A. lumbricoides: 4.3%; T. trichiura: 0.2%). Other helminth species observed were Schistosoma mansoni (5.0%), Hymenolepis nana (2.7%), Taenia spp. and Enterobius vermicularis (<1.0%). The analysis of the nail material revealed the presence of A. lumbricoides (1.7%), Taenia spp. (1.0%), T. trichiura (0.5%), E. vermicularis (0.5%) and H. nana (0.2%). The odds of infection with any STH increased as the frequency of trimming decreased. The odds of nail contamination with any STH and A. lumbricoides were higher for younger children.ConclusionsThe presence of helminth eggs under the nails of children highlights a poor personal hygiene. The association between any STH infection and frequency of nail trimming needs to be explored in an intervention study. The recent prevalence of any STH infections indicated that scaling down of the frequency of deworming is justified but that STH is still a public health problem.
