A cross-sectional survey of SARS-CoV-2 in domestic dogs and cats was conducted in high-risk areas, five subdistricts of Samut Sakhon Province, the epicenter of the second wave of the COVID-19 outbreak in Thailand in February 2021. A total of 523 swab samples (nasal, oral, and rectal swabs) and 159 serum samples from dogs (n = 83) and cats (n = 93) were collected and tested for SARS-CoV-2 RNA and antibodies. All swab samples tested negative for SARS-CoV-2 RNA by real-time RT-PCR with three panels of specific primers and probes. Although all dogs and cats were negative for SARS-CoV-2 RNA, 3.14% (5/159) had anti-N-IgG antibodies against SARS-CoV-2 by indirect multispecies ELISA. Our results demonstrated SARS-C... More

Although all dogs and cats were negative for SARS-CoV-2 RNA, 3.14% (5/159) had anti-N-IgG antibodies against SARS-CoV-2 by indirect multispecies ELISA. Our results demonstrated SARS-CoV-2 exposure in domestic animals living in high-risk areas during the second wave of the COVID-19 outbreak in Thailand. Thus, the use of one health approach for monitoring SARS-CoV-2 in domestic animals in high-risk areas of COVID-19 outbreaks should be routinely conducted and will provide benefits to risk communications in communities.
