Assessment of Risk Factors Associated with and Practices of Cattle Farmers in Kirehe District Rwanda with Respect to Vector-Borne and Zoonotic Pathogens.

Abstract

Rural Rwandan communities face health challenges for humans and animals, and the topography and climate of the Kirehe District of Rwanda put farmers at high risk for mosquito-borne diseases. Individuals from 92 Rwandan farms were surveyed about farm practices, as well as animal and human health histories between December 2017 and February 2018. Human, animal, and environmental factors were investigated to determine whether there is a pattern of risk for abortion incidence and/or history of malarial disease on the farm. Iterative, complementary logistic regression models were used to determine whether there was an association between variables and abortion history in animals. These factors were then used to investigate association with a reported history of malaria. Of the 92 farms in our study, 82 were family farms and 10 were commercial farms. On average, 88% of the farms had cattle, and 30% of farms had experienced a cattle abortion in the past 2 years. There was no observed statistical significance in the risk factors for history of abortion in cattle and the measured variables. Using One Health as a guiding framework, we sought to determine whether human, animal, and environmental factors were statistically associated with observed disease outcomes. From our study of the practices of the farmers with respect to biosafety and self-protection against disease, we have identified potential sources of risk that could be targeted to enhance education and protection on these farms.
