“…We tested 30 cats and 1 dog sera, and only the dog sera tested positive. A study conducted in Poland revealed that the seroprevalence of 2.21% of tested dogs was positive for influenza type A virus [ 20 ]. However, in Italy, none of the dog or cat sera tested positive during the concurrent circulation of AIV subtypes [ 21 ].…”

Background and Aim: Influenza type A virus infections are still one of the major concerns for the health of humans and various species of domestic and companion animals. Wild birds play an essential role in the transmission cycle of the virus. Regularly monitoring the spread of the virus is a significant step in its mitigation. Highly pathogenic avian influenza viruses, including H5N1 and H5N8, have been reported in birds in the Arabian Peninsula, including Saudi Arabia, in recent decades. This study aimed to evaluate the immune status of birds, domestic and companion animals for Influenza type A virus in Eastern Province of Saudi Arabia. Materials and Methods: We collected 195 serum samples from dromedary camels, sheep, goats, native breed chickens, doves, dogs, and cats. We tested these sera for the presence of specific antibodies against influenza type A virus using a commercially available enzyme-linked immunosorbent assay. Results: Our results show that 4% of the tested samples had antibodies in sera, including some doves, chickens, and dogs. These data suggest exposure and seroconversion of these animals or birds to the influenza type A virus. Conclusion: The presence of antibodies against influenza type A virus in sera of some animals and birds without a previous vaccination history against the virus indicates a natural exposure history regarding this virus and seroconversion. Further large-scale molecular and epidemiological studies are needed to obtain a better understanding of the dynamics of influenza type A virus among various species of animals and birds.

Influenza A viruses (IAV) are zoonotic pathogens that can cause significant illness in wild and domestic animals, and humans. IAV can infect a broad range of avian and mammalian species, depending on subtype, and avian IAV can be moved over relatively long distances by migratory birds. Although spillover infections from wildlife or domestic animals to humans are an important part of the transmission cycle that can drive outbreaks, the relevance of companion animals, specifically dogs and cats, is not fully understood. A novel pandemic H1N1 reassortant (H1N1pdm09) emerged from swine in 2009, infecting humans, and wild and domestic animals worldwide. During a 2016 human influenza outbreak in Kyiv, subtype H1N1pdm09 predominated and was associated with severe disease and deaths; however, H3N2 and influenza B viruses were also detected. No case of avian influenza in humans was detected. To investigate potential involvement of companion animals, animals in a veterinary hospital (116 cats and 88 dogs) were randomly selected, and sera were tested using a commercially available IAV nucleoprotein enzyme-linked immunosorbent assay. Twelve of 203 serum samples were positive for influenza antibodies (5.7% of dogs and 6.08% cats). These are the first data to demonstrate influenza A infection of pets in Ukraine, highlighting the potential risk of infection of companion animals from close contact with humans.

“…However, dog‐associated IAVs are an imminent threat of risk in IAV transmission that should not be neglected because of all the ecological and epidemiological characteristics associated with dogs that may give rise to epidemic or pandemic viral variants. These characteristics are not only associated with dogs living in backyard production systems but also extend to companion dogs that maintain close contact with other companion species and humans in cities or peri‐urban areas, as well as stray dogs, as demonstrated in numerous studies that determine the participation of dogs in IAV exposure and transmission (Borland et al., 2020; Jimenez‐Bluhm et al., 2021; Klivleyeva et al., 2022; Kovalenko et al., 2021; Kwasnik et al., 2020; Ramírez‐Martínez et al., 2013; Song et al., 2012; Wang et al., 2019; Zhao et al., 2020).…”

AimsThis study aimed to identify exposure to human, swine, and avian influenza A virus subtypes in rural companion and hunting dogs, backyard pigs, and feral pigs.Methods and ResultsThe study took place in a region of southeastern Mexico where the sampled individuals were part of backyard production systems in which different domestic and wild species coexist and interact with humans. We collected blood samples from pigs and dogs at each of the sites. We used a nucleoprotein enzyme‐linked immunosorbent assay to determine the exposure of individuals to influenza A virus. Haemagglutination inhibition was performed on the positive samples to determine the subtypes to which they were exposed. For data analysis, a binomial logistic regression model was generated to determine the predictor variables for the seropositivity of the individuals in the study. We identified 11 positive individuals: three backyard pigs, four companion dogs, and four hunting dogs. The pigs tested positive for H1N1 and H1N2. The dogs were positive for H1N1, H1N2, and H3N2. The model showed that dogs in contact with backyard chickens are more likely to be seropositive for influenza A viruses.ConclusionsWe demonstrated the essential role hunting dogs could play as intermediate hosts and potential mixing vessel hosts when exposed to human and swine‐origin viral subtypes. These results are relevant because these dogs interact with domestic hosts and humans in backyard systems, which are risk scenarios in the transmission of influenza A viruses. Therefore, it is of utmost importance to implement epidemiological surveillance of influenza A viruses in backyard animals, particularly in key animals in the transmission of these viruses, such as dogs and pigs.
