Situation: Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2): A virus that is spreading globally through human-to-human transmission, but has also demonstrated ability to infect multiple animal species (from Bovidae, Canidae, Cebidae, Cercopithecidae, Cervidae, Cricetidae, Felidae, Hominidae, Hyaenidae, Mustelidae, Procionidae, Viverridae, Hippopotamidae, Myrmecophagidae families) with spillover potential from one animal species to another. In rare occasions, spill-back from animals to humans has been evidenced (mink-to-human in the Netherlands [reference] and in Denmark [reference]; hamster-to-human in Hong Kong Special Administrative Region (China) [reference]).
Reported human cases: As of 5 December 2022, there have been 641 435 884 confirmed cases of COVID-19 including 6 621 060 deaths reported to WHO. In the last seven
days,
2 716 294 new human cases and 6 629 deaths were reported worldwide. Since the beginning of the pandemic in March 2020, 233 countries, states, and territories reported
COVID-19 human cases across five geographic regions including Africa (57), the Americas (57), Asia (46), Europe (50), and Oceania (23). [reference].

2 Though RNA detected in some in-contact animals but none of them seroconverted.
Arteaga, F. L., Jodar, M. N., Mondino, M., Portu, A., Boeris, M., Joly, […] & Bratanich, A. (2022). An outbreak of SARS-COV-2 in big hairy armadillos (chaetophractus villosus) associated with gamma variant in Argentina three months after being undetectable in humans. bioRxiv 2022.08.23.503528. [reference]. SARS-CoV-2 Gamma variant infection confirmed by RT-PCR in four specimens of Chaetophractus villosus (big hairy armadillo/armadillo peludo) in Argentina three months after its last detection in humans, raising the question of potential unidentified viral reservoirs. The sequencing data from three animals clearly points to a single transmission event to the animals. The nonsynonymous mutations identified in Chaetophractus villosus have not been reported previously in other animals infected naturally or experimentally with SARS-CoV-2 Gamma variant.
Bae, D. Y., Tark, D., Moon, S. H., Oem, J. K., Kim, W. I., […] & Cho, H. S. (2022). Evidence of Exposure to SARS-CoV-2 in Dogs and Cats from Households and Animal Shelters in Korea. Animals: an open access journal from MDPI, 12(20), 2786. [reference]. SARS-CoV-2 viral RNA was detected in 2 cats out of 1018 pets (672 dogs and 346 cats). A total of 16 dogs (2.38%) and 18 cats (5.20%) tested positive using ELISA, and 14 dogs (2.08%) and 17 cats (4.91%) tested positive using PRNT. Antigens of- and/or antibodies to SARS-CoV-2 were detected in the animals regardless of whether the companion family was infected; this was the case in animal shelters, which have been regarded as relatively safe from transmission.
Caserta, L., Martins, M., Butt, S., Hollingshead, N., Covaleda, L., […] & Diel, D. (2022). White-tailed deer (Odocoileus virginianus) may serve as a wildlife reservoir for nearly extinct SARS-CoV-2 variants of concern. bioRxiv 2022.09.02.506368. [reference]. A total of 5,462 retropharyngeal lymph node samples collected from free-ranging hunter-harvested White-tailed deer during the hunting seasons of 2020 and 2021 and tested for SARS-CoV-2 detection by real-time RT-PCR. The virus RNA was detected in 17 samples (0.6%) from 2020 and in 583 (21.1%) samples from 2021, the gene sequence analysis from 164 samples demonstrated the presence multiple SARS-CoV-2 lineages as well as the co-circulation of three variants of concern (Alpha, Gamma, and Delta). The analyzed data suggested the occurrence of multiple spillover events (human-to-deer) of the Alpha and Delta variants with subsequent deer-to-deer transmission of the viruses. Detection of Alpha and Gamma variants in white tailed deer long after their broad circulation in humans in suggests that this animal species may serve as a wildlife reservoir for variants of concern no longer circulating in humans.

Fernández-Bastit, L., Roca, N., Romero-Durana, M., Rodon, J., Cantero, G., […] & Lorca-Oró, C. (2022). Susceptibility of Domestic Goat (Capra aegagrus hircus) to Experimental Infection with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) B.1.351/Beta Variant. Viruses, 14(9). [reference]. This experimental infection study demonstrated low susceptibility of goats to SARS-CoV-2 Beta variant, the virus RNA was detected in nasal swabs and tissues by RT-qPCR and/or immunohistochemistry, and seroneutralisation was confirmed via ELISA and live virus neutralisation assays. However, the viral amount and tissue distribution suggest a low susceptibility of goats.
Goldberg, A., Langwig, K., Marano, J., Sharp, A., Brown, K., Ceci, A. […] & Hoyt J. (2022). Wildlife exposure to SARS-CoV-2 across a human use gradient. bioRxiv 2022.11.04.515237. [reference]. 18 different wildlife species in the Eastern U.S. were samples for the detection of exposure to SARS-CoV-2. Using quantitative reverse transcription polymerase chain reaction and whole genome sequencing, SARS-CoV-2 RNA detected in the Virginia opossum and had equivocal detections in six additional species. Species considered human commensals like squirrels, and raccoons had high seroprevalence, ranging between 62%-71%. The whole genome sequence of the SARS-CoV-2 variant infecting the opossum revealed several mutations shared within the Omicron clade as well as unique amino acid substitutions not previously identified in other human-infected SARS-CoV-2 virus at the time of collection
Hoppe, J. M., Füeßl, L. U., Hartmann, K., Hofmann-Lehmann, R., Graf, A., […] & Muenchhoff, M. (2022). Secondary zoonotic dog-to-human transmission of SARS-CoV-2 suggested by timeline but refuted by viral genome sequencing. Infection, 1–7. Advance online publication. [reference]. This study report on a 44-year-old COVID-19 human patient, who reported that his dog displayed respiratory signs shortly prior to his infection. The dog tested real-time-PCR positive for SARS-CoV-2 RNA and the timeline of events suggested a transmission from the dog to the patient.
Kaczorek-Łukowska, E., Wernike, K., Beer, M., Wróbel, M., Małaczewska, J., […] & Siwicki, A. K. (2022). High Seroprevalence against SARS-CoV-2 among Dogs and Cats, Poland, 2021/2022. Animals: an open access journal from MDPI, 12(16), 2016. [reference]. Serum samples were collected from a total of 388 dogs and 243 cats from three veterinary clinics in Poland between October 2021 and February 2022, when the country was during the fourth wave of viral spread. 18.9% of the feline sera and 16.0% of the canine sera tested positive for SARS-CoV-2 antibodies using ELISA and immunofluorescence assay. This relatively high seroprevalence among randomly selected animals is most likely related to the high case numbers in the human population and indicates a continuous occurrence of trans-species virus transmissions from infected owners to their pets.
Krupińska, M., Borkowski, J., Goll, A., Nowicka, J., Baranowicz, K., […] & Grzybek, M. (2022). Wild Red Deer (Cervus elaphus) Do Not Play a Role as Vectors or Reservoirs of SARS-CoV-2 in North-Eastern Poland. Viruses, 14(10), 2290. [reference]. In this study serum and nasopharyngeal swabs were collected from 90 red deer shot by hunters in five hunting districts in Poland. None of the collected samples tested positive for anti-SARS-CoV-2 antibodies or SARS-CoV-2 RNA using immunofluorescent and real-time PCR with reverse transcription, respectively.
Lawton, K., Keller, S. M., Barnum, S., Arredondo-Lopez, C., Spann, K., Pusterla, N. (2022). Seroprevalence of SARS-CoV-2 in 1186 Equids Presented to a Veterinary Medical Teaching Hospital in California from 2020 to 2022. Viruses, 14(11), 2497. [reference]. The aim of this study was to determine the seroprevalence of SARS-CoV-2 and selected prevalence factors in equids presented to a Veterinary Medical Teaching Hospital over a two-year period using ELISA targeting the receptor binding domain of the SARS-CoV-2 spike protein. 42/1186 (3.5%) horses had detectable SARS-CoV-2 antibodies. Amongst the prevalence factors investigated, only seasonality (spring) was associated with a greater frequency of seropositivity. Horses with medical and surgical complaints were more likely to test seropositive to SARS-CoV-2.

(2022) Clinical and epidemiologic features of SARS-CoV-2 in dogs and cats compiled through national surveillance in the United States. Researchsquare preprints. [reference]. This study aimed to characterizing the clinical and epidemiologic features of SARS-CoV-2 in companion animals detected in the U.S. Data on 204 companion animals (109 cats, 95 dogs) with confirmed SARS-CoV-2 infections between March 2020 and December 2021 were analyzed. Among dogs and cats identified through passive surveillance, 94% (n=87) had reported exposure to a person with COVID-19 before infection. Clinical signs of illness were present in 74% of pets identified through passive surveillance and 27% of pets identified through active surveillance. Duration of illness averaged 15 days in cats and 12 days in dogs. The average time between human and pet onset of illness was 10 days. Viral nucleic acid was first detected at 3 days post exposure in both cats and dogs. Antibodies were detected starting 5 days post exposure and titers were highest at 9 days in cats and 14 days in dogs.
Mahajan, S., Karikalan, M., Chander, V., Pawde, A. M., Saikumar, G., […] & Sharma, G. K. (2022). Detection of SARS-CoV-2 in a free ranging leopard (Panthera pardus fusca) in India. European journal of wildlife research, 68(5), 59. [reference]. This study reports an incidence of natural infection of SARS-CoV-2 in free-ranging Indian leopard (Panthera pardus fusca). The case was detected during routine screening. Post-mortem and laboratory examination suggested virus-induced interstitial pneumonia. Viral genome could be detected in various organs including brain, lung, spleen, and lymph nodes by real-time PCR. Whole-genome sequence analysis confirmed infection with Delta variant.
Marques, A. D., Sherrill-Mix, S., Everett, J. K., Adhikari, H., Reddy, S., […] & Anis, E. (2022). Multiple Introductions of SARS-CoV-2 Alpha and Delta Variants into White-Tailed Deer in Pennsylvania. mBio, 13(5), e0210122. [reference]. 123 nasal swab samples were collected during 2021 from hunter-harvested deer and injured deer within hours of death. 20 (16.3%) samples were positive for SARS-CoV-2 by RT-qPCR. Seven whole genome sequences were obtained, together with six more partial spike gene sequences. These annotated as alpha and delta variants, the first reported observations of these lineages in deer, documenting multiple new jumps from humans to deer. The alpha lineage persisted in deer after its displacement by delta in humans, and deer-derived alpha variants diverged significantly from those in humans, consistent with a distinctive evolutionary trajectory in deer.

SARS-CoV-2 in a Mink Farm in Italy: Case Description, Molecular and Serological Diagnosis by Comparing Different Tests. Viruses, 14(8), 1738. [reference]. This study describes SARS-CoV-2 infection in minks on an Italian farm after one of the farm workers tested positive by RT-PCR. Diagnostic tests detected only four weak PCR-positive mink samples out of 1909 samples tested, but 100% (n=74) of sera were positive for SARS-CoV-2 antibodies. The phylogenetic analysis of two SARS-CoV-2 sequences from two minks and the sequence of the worker showed that they belonged to different clades.

Serological evidence of SARS-CoV-2 infection in pets naturally exposed during the COVID-19 outbreak in Argentina. Veterinary immunology and immunopathology, 254, 110519. Advance online publication. [reference]. The present study aimed to detect SARS-CoV-2 antibodies by ELISA and virus neutralization test in pets owned by previously confirmed as COVID-19 human cases in Argentina. Three out of the seven cats and 14 out of the 31 dogs were positive for SARS-CoV-2 by ELISA, and one cat and six dogs showed the presence of neutralizing antibodies.
Pickering, B., Lung, O., Maguire, F., Kruczkiewicz, P., Kotwa, J. […] & Bowman, J. (2022). Divergent SARS-CoV-2 variant emerges in white-tailed deer with deer-to-human transmission. Nat Microbiol 7, 2011–2024. [reference]. This study conducted in Ontario, Canada during November and December 2021 (n = 300 deer) and identified a highly divergent lineage of SARS-CoV-2 (B.1.641) in white-tailed deer. This lineage is one of the most divergent SARS-CoV-2 lineages identified so far, with 76 mutations (including 37 previously associated with non-human mammalian hosts). From a set of five complete and two partial deer-derived viral genomes the phylogenomic, recombination, selection and mutation spectrum analyses provided evidence for evolution and transmission in deer and a shared ancestry with mink-derived virus. The analysis also revealed an epidemiologically linked human infection.
Robinson, SJ., Kotwa, JD., Jeeves, S., Himsworth, C., Pearl, D., […] & Jardine C. 2022. Surveillance for SARS-CoV-2 in Norway rats (Rattus norvegicus) from southern Ontario. Authorea Preprints; PPR539706. [reference]. 224 rats were submitted by collaborating pest control companies from October 2019 to June 2021, of them 202 samples were collected prior to the emergence of VOCs, and 22 were collected while the Alpha variant was the predominant circulating VOC in humans. Nasal turbinate and small intestinal tissue samples were analyzed for SARS-CoV-2 RNA by RT-PCR. Thoracic cavity fluid samples were tested for neutralizing antibodies using a surrogate virus neutralization test (sVNT), the plaque reduction neutralization test (PRNT) was conducted on presumptive positive samples. SARS-CoV-2 RNA was not detected in any samples tested while two out of eleven samples positive by sVNT had neutralizing antibodies by PRNT.

Neutralizing antibodies against the SARS-CoV-2 ancestral strain and Omicron BA.1 subvariant in dogs and cats in Mexico. Authorea. August 19. [reference]. A total of 1111 samples from dogs (n=1052) and cats (n=59) were collected in different regions of Mexico, and the presence of neutralizing antibodies was evaluated by a plaque reduction neutralization test (PRNT90) and microneutralization. The results showed that 15.25% (9 of 59) of cats and 2.85% (30 of 1052) of dogs are seropositive against the ancestral strain of SARS-CoV-2. However, the analysis of neutralizing antibodies against Omicron BA.1 in cats showed the same percentage of positive animals but a reduction in the titer while in the case of dogs, 2.09% (22 of 1052) showed neutralizing antibodies against Omicron BA.1.

No Evidence of SARS-CoV-2 Infection in Wild Mink (Mustela lutreola and Neogale vison) from Northern Spain during the First Two Years of Pandemic. Animals: an open access journal from MDPI, 12(15), 1971. [reference]. From January 2020 to February 2022, a total of 162 animals (127 European mink and 35 American mink) were sampled to evaluate the presence of SARS-CoV-2. Antibodies against the SARS-CoV-2 were not found in the serum samples (n = 126) analysed by ELISA nor was the virus amplified by RT-qPCR (n = 160 swabs).

[reference]. This field and experimental infection study evaluated SARS-CoV-2 exposure among 79 rats captured from New York City during the fall of 2021. The results showed that 13 (16.5%) rats tested IgG or IgM positive by ELISA however, none of them tested positive by microneutralization assays against the B.1 lineage and the Alpha and Delta variant. Four (5%) of the tissue samples were positive by qRT-PCR. To investigate whether Alpha, Delta, or Omicron variants are capable of infecting rats, these variants were intranasally inoculated in 6-week-old wild-type Sprague Dawley rats, the results showed that Alpha, Delta, and Omicron variants can cause robust infections in the inoculated rats, including high level replications in the upper and lower respiratory tracts and induction of both innate and adaptive immune responses. Additionally, the Delta variant resulted in the highest infectivity.
Within FAO’s COVID-19 Recovery and Response Programme, several projects are already in place as part of Preventing the Next Zoonotic Pandemic (PNP), that help countries to better prevent and mitigate risks related to SARS-CoV-2 at the animal-human interface and build national capacities in pandemic preparedness (see below for details).
Regional level
Through these projects and others, FAO is supporting countries in West and Central Africa since the beginning of the pandemic in mitigating negative impacts of COVID-19 by:
