Abstract
Multiple transboundary animal diseases (TADs) circulate in Plateau State, Nigeria, where livestock keeping is common and contributes to both the physical and socio-economic well-being of a large proportion of the population. In this study, we explored the potential for environmental sampling to detect viruses causing TADs circulating in the region. Electrostatic dust cloths were used to swab areas of the environment likely to have contact with secretions and excretions from infected animals. Samples were collected monthly from five households, one transhumance site and one livestock market in two local government areas in Plateau State between March and October 2021. These were tested for the presence of peste des petits ruminants virus (PPRV) and capripox viruses using real-time PCR. Of the 458 samples collected, 2.4% (n = 11) were positive for PPRV RNA and 1.3 % (n = 6) were positive for capripox virus DNA. A capripox differentiation assay showed that these samples were positive for sheep pox virus (n = 2), goat pox virus (n = 2) and lumpy skin disease virus (n = 2). Our results demonstrate that environmental sampling could be used as part of TAD surveillance in the area. Environmental swabs require little technical knowledge to collect and can be used to detect multiple viruses from a single sample.
