“…This finding is consistent with previous reports of infection with EDS'76 in poultry elsewhere (Brash et al, 2009;Cha et al, 2013), including the fact that most backyard poultry are not vaccinated against EDS'76 (Clark, 2019), and that affected birds are apparently healthy (Ezema et al, 2008). The backyard poultry system is usually confronted with poor management, lack of veterinary care and poor disease control which contribute to low productivity and high mortality rates (Salihu et al, 2010). Most of the birds in this study were allowed to scavenge which could allow for unrestricted spread of the disease and contribute to the high prevalence of EDSV'76 antibodies in these birds.…”

“…Since its initial description, EDS'76 has been a major cause of loss in egg production as a result of production of eggs with abnormal shell shapes and sometimes shell-less eggs (Van Eck et al, 1976;Salihu et al, 2010). The detection of EDSV'76 antibodies in apparently healthy birds in this study revealed the circulation of the virus in Japanese quails, turkeys, ducks, indigenous chickens and guinea fowls raised in backyard poultry systems in Oyo and Osun states.…”

In Nigeria, egg drop syndrome 1976 (EDS’76), unlike other poultry diseases, has been given little attention as a cause of economic losses due to decreased egg production, particularly in backyard poultry flocks. This study aimed to investigate the presence of EDS’76 virus in backyard poultry flocks in Oyo and Osun states, Southwestern Nigeria. Blood samples were collected in 24 farms from 218 apparently healthy, unvaccinated birds which comprised 30 Japanese quails, 75 turkeys, 30 ducks, 57 indigenous chickens and 26 guinea fowls. Indirect ELISA was used to detect anti-EDS’76 virus antibodies in sera from the birds, and poultry owners were interviewed on their purposes with regard to bird raising. Overall, 139 (63.8%) sera were positive for EDS’76 with 26.7% (8/30), 90.7% (68/75), 33.3% (10/30), 89.5% (51/57) and 7.7% (2/26) from Japanese quails, turkeys, ducks, indigenous chickens and guinea fowls, respectively. Some of the farmers practiced placing eggs from guinea fowls under brooding indigenous hens for natural incubation, or sold eggs from turkeys and ducks to commercial hatcheries. Our findings suggest that these bird species serve as reservoirs of EDS’76 virus with the probable involvement of backyard poultry in its transmission, particularly to commercial poultry and other birds in Southwestern Nigeria. Thus, backyard poultry should be included in anti-EDS’76 vaccination schedules in the country.

“…The first documented confirmed outbreak of ND in Nigeria occurred between December 1952 and February 1953 in and around Ibadan [53]. The disease has since that time remained a major threat to the Nigerian poultry industry [124]. An average of 200 -250 outbreaks of ND is reported annually in Nigeria [119,123].…”

“…It still remains a major constraint to successful poultry production in Nigeria with outbreaks resulting to up to 100% mortalities [125]. Over time, epizootiology of Newcastle disease in Nigeria has been based mostly on conventional methods such as serology [113][114][115][116][117][118][119][120][121][122][123][124][125][126][127][128] and biological characterization in conjunction with virus isolation [117,119,129,130]. Antibodies to NDV have been found in several species of poultry across the nation using serological techniques [haemagglutination-inhibition (HI) or Enzyme-linked immune sorbent test (ELISA)] [130][131][132].…”

Introduction: Newcastle disease is a highly contagious illness and one of the "notifiable illnesses" on the World Health Organization list for Animal Health (OIE) Outcome. There are constantly new cases being reported as new NDV isolates from around the world. Newcastle disease poses a significant global economic threat to the poultry sector, causing highly contagious and transmissible diseases in birds with huge food security threat among the weak and vulnerable developing and underdeveloped countries Aim: The aim of this article borders on bringing to light the risk of possible Newcastle disease outbreak in Nigeria due to increasing poor management of poultry farms and poultry waste product. Furthermore, it will also underscore and outline various ways which can be adopted to prevent this poultry disease which is of great public health, economic and food security protection importance. Method/Methodology: This is a systematic review of published research articles focusing on Newcastle disease, epidemiology, pathogenicity, transmission and factors that can play important roles in the possible outbreak of the disease in poultries. Studies reviewed comprise of cross-sectional, prospective, longitudinal and observational studies. The study approach follows the systematic review of peer-reviewed published articles as well as online publications and articles derived from various databases with search keywords relevant to the topic of discourse. Findings and Results: The findings in this study highlight the endemicity of Newcastle virus disease in various part of the country, and how the severity of the disease is influenced by host characteristics, viral properties, and environmental factors. The study pointed out critical evidence-based possible reasons that could promote a new round of Newcastle disease epidemic outbreak as a result of poor poultry management practices such as high bird densities, poor poultry infrastructure, lack of quarantine of sick birds, mixed species rearing, free range system of poultry, poor waste disposal, lack of expertise, and insufficient biosecurity outcomes. However, the lack of education and awareness among farmers exacerbates the problem, hindering preventive measures. The complexity is increased by difficulties with vaccination, unrestrained bird movement through trading with neighboring countries and interstate, and a lack of diagnostic facilities. The consequences of an outbreak extends beyond financial losses to potential disruptions in the poultry supply chain, food security risks, and public health concerns. Conclusion and Recommendation: The growing difficulties in poultry management methods increases the serious public health concern posed by a possible Newcastle Virus epidemic outbreak in Nigeria. A paradigm shift in poultry farming practices is necessary to address this problem. A comprehensive strategy that incorporates infrastructural development, regulatory frameworks, and education in order to strengthen the poultry industry is needed, so as to address and prevent the looming public health and food security crises that may break out from the above scenario
