“…Although PCV2 is ubiquitous (Franzo & Segalés, 2018), there is a lack of information on PCV2 from the Lesser Antilles. To date, the only data available from the region are that on the presence of serum antibodies to PCV2 in pigs on Trinidad and Tobago (Sookhoo et al., 2017).…”

Porcine circovirus 2 (PCV2), a member of the family Circoviridae, is an economically important pathogen of swine (Segalés, Kekarainen, & Cortey, 2013). PCV2 has been associated with a variety of porcine disease conditions that include post-weaning multisystemic wasting syndrome (PMWS), porcine dermatitis and nephropathy syndrome (PDNS), porcine respiratory disease complex (PRDC), reproductive disorders and enteritis (Opriessnig, Meng, & Halbur, 2007; Segalés, 2012). These clinical and subclinical manifestations, collectively known as porcine circovirus-associated diseases (PCVAD), cause significant economic losses to the pork industry worldwide (Opriessnig et al., 2007).

The global anxiety and a significant threat to public health due to the current COVID-19 pandemic reiterate the need for active surveillance for the zoonotic virus diseases of pandemic potential. Influenza virus due to its wide host range and zoonotic potential poses such a significant threat to public health. Swine serve as a "mixing vessel" for influenza virus reassortment and evolution which as a result may facilitate the emergence of new strains or subtypes of zoonotic potential. In this context, the currently available scientific data hold a high significance to unravel influenza virus epidemiology and evolution. With this objective, the current systematic review summarizes the original research articles and case reports of all the four types of influenza viruses reported in swine populations worldwide. A total of 281 articles were found eligible through screening of PubMed and Google Scholar databases and hence were included in this systematic review. The highest number of research articles (n = 107) were reported from Asia, followed by Americas (n = 97), Europe (n = 55), Africa (n = 18),

“…While the ELISA assay detected IAV antibodies in 14 (10.07%) sera obtained from Trinidad, the sera from Tobago were negative for IAV seroprevalence. Among the ELISA positive samples from Trinidad, H3N2 and pandemic A(H1N1)pdm09 virus clade 1A.3.3.2 virus antibodies were detected by the HI assay [ 45 ]. These data suggested a past circulation of IAV, which appeared to be confined to the island of Trinidad, while no past IAV exposure was detected in the backyard swine on the island of Tobago in this investigation.…”

Background Backyard swine farming is critical to generating subsistence and food security in rural and peri-urban households in several developing countries. The objective of this systematic review was to analyze the molecular and serological prevalence of influenza A virus (IAV) in backyard swine populations globally. Results We identified 34 full-text research articles in NCBI-PubMed and Google Scholar databases that have reported IAV sero- and/or virological prevalence in backyard swine up to 11 July 2021. The highest number of studies were reported from Asia (n = 11) followed by North America (n = 10), South America (n = 6), Africa (n = 6), and Europe (n = 1). While the maximum number of studies (44.12%) reported human-to-swine transmission of IAV, swine-to-human (5.88%), poultry-to-swine (5.88%), and wild birds-to-swine (2.94%) transmissions were also reported. An overall higher IAV seroprevalence (18.28%) in backyard swine was detected compared to the virological prevalence (1.32%). The human-origin pandemic A(H1N1)pdm09 virus clade 1A.3.3.2 was the more frequently detected IAV subtype in virological studies (27.27%) than serological studies (18.92%). In addition, the avian-origin highly pathogenic H5N1 and H5N8 viruses were also detected, which further substantiated the evidence of avian–swine interactions in the backyards. Conclusion Human–swine and avian–swine interactions in backyards may transmit IAV between species. Monitoring the circulation and evolution of IAV in backyard swine would help stakeholders make informed decisions to ensure sustainable backyard swine farming and public safety.
