Pig production is an important livestock subsector contributing immensely to food security and household income generation, especially in developing countries. Rotavirus infections, which are the leading cause of dehydrating diarrhoea in piglets, hinder their productivity. To date, there are ten Rotavirus groups (A-J) detected and distributed in both humans and animals, with some strains demonstrating zoonotic potential. Some of the risk factors of Rotavirus infection in pig farms include: age of pigs, herd size, presence of other animals, farm management practices and overall sanitation. Evolution of these viruses, especially through reassortment events, has led to the development of novel genotypes with implications for both animal and human health. Rotaviruses are genetically diverse and persist in the environment, and therefore, frequent surveillance, especially molecular characterisation, is of vital importance in the mitigation of these viruses. This review highlights the structure of Rotaviruses, epidemiologic surveillance efforts, identified risk factors, and the potential for interspecies transmission. It also aims to identify research gaps, particularly regarding antigenic variation of circulating strains in pigs within developing countries. Improved surveillance and control measures are essential for enhancing pig health and maximising the economic benefits of pig production.
