This study evaluated the social and economic impact of non-typhoidal salmonellosis (NTS) infection in Nigeria. Results showed that in 2020, NTS infection led to 325,731 cases and 1043 human deaths, with a disability-adjusted life year (DALYs) of 37,321. The cost associated with human infection was estimated at US$ 473,982,068, while the loss in poultry was estimated at US$ 456,905,311. This research provides empirical evidence to support decision-making and investments in controlling and eradicating human and poultry salmonellosis (NTS) in Nigeria.
Background: The non-typhoidal salmonellosis (NTS) is a pathogenic bacterial zoonosis with substantial but often under-appreciated public health impacts. The NTS is prevalent in poultry and humans in Nigeria, yet its eco-nomic and social burden have not been determined through any empirical study. To bridge the gap, we evaluated the impact of NTS in social and economic terms. Methods: Relevant population, economic and epidemiological data were retrieved from peer-reviewed publica-tions, open sources and relevant authorities. Additional data were obtained through experts' opinions and field surveys. Using a customized and validated Microsoft Excel (R) tool, economic analysis was conducted. Results: Using the year 2020 reference point, the burden of NTS was 325,731 cases and a total of 1043 human deaths, at a disability-adjusted life year (DALYs) of 37,321. The cost associated with infection in humans was US$ 473,982,068. A total loss of US$ 456,905,311 was estimated in poultry including the direct value of animal loss, US$ 224,236,769, loss from salvage slaughter and culling, US$ 220,386,556, and value of foregone production, US$ 12,281,987. Interpretation: The outcomes of this important work provide empirical evidence to support informed decisions and investments in the control and eradication of human and poultry salmonellosis (NTS) in Nigeria.
