COVID-19 and One Health: potential role of human and animals in SARS-CoV-2 life cycle

Serological Assay for SARS-CoV-2 in Domestic and Wild Animals in Middle and Southeast Regions in Brazil

“…The overall seroprevalence of anti-SARS-CoV-2 antibodies in domestic animals was significantly higher than that observed in wild animals. According to previous studies, the main mode of transmission of SARS-CoV-2 to animals is close contact with humans [26][27][28][29]. Therefore, as of June 2023, Brazil has reported more than 37 million cases of COVID-19, according to WHO data.…”

“…With the high prevalence of cases among humans, the human-to-animal transmission of the virus is likely to be proportionally increased [26][27][28][29].…”

Global One Health index for zoonoses: A performance assessment in 160 countries and territories

“…6 In the last ten years, the world has faced several international public health emergencies of zoonotic origin, including the Middle East respiratory syndrome (MERS), Ebola, and coronavirus disease 2019 (COVID-19) pandemics. 7 , 8 …”

SARS‐CoV‐2 Reverse Zoonosis Among Cats in China: A One Health Investigation

“…This approach may stimulate more research into reverse zoonoses. In the last two decades, reverse zoonosis has gained attention of researchers because of zoonotic disease outbreaks (H5N1, H1N1, SARS, MERS, SARS-CoV-2) seriously impacting human health and economy [5]. Fagre et al [6] documented that several pathogens including virus and bacteria are being passed from people to wild animals and reverse zoonosis events are happening continuously; however, we are not picking them up largely due to less robust sampling and veterinary diagnostic tools.…”

“…However, screening for SARS-CoV-2 during feline respiratory disease complex could be relevant from human reinfection standpoint [10]. Since cat-to-human transmission has already been reported [5,8], therefore, vaccination of cats against SARS-CoV-2 should be considered along with animal owners as additional measure. Vaccination could reduce virus replication and host to host transmission of SARS-CoV-2.…”
