在最近的报告中，已经调查了家畜在SARS-CoV-2向人类传播和传播中的流行病学作用，但有些方面需要进一步澄清。到目前为止，只有在极少数情况下，与COVID-19患者生活在一起的狗和猫被发现携带SARS-CoV-2，没有证据表明宠物传播给人类。本研究的目的是验证狗和猫在与COVID-19患者密切接触时是否作为SARS-CoV-2的被动机械携带者。从COVID-19患者拥有的48只狗和15只猫收集的皮肤和趾间拭子通过qRT-PCR检测SARS-CoV-2。从主人拭子阳性到宠物样本采集之间的时间范围为1至72天，犬的中位时间为23天，猫为39天。所有样本的检测结果均为阴性，这表明宠物的毛发和脚垫上并不被动携带SARS-CoV-2，因此它们在病毒传播给人类方面可能并不起重要作用。这些数据可能有助于确认与宠物的毛发和护垫的直接接触并不代表SARS-CoV-2的传播途径。
The epidemiological role of domestic animals in the spread and transmission of SARS-CoV-2 to humans has been investigated in recent reports, but some aspects need to be further clarified. To date, only in rare cases have dogs and cats living with COVID-19 patients been found to harbour SARS-CoV-2, with no evidence of pet-to-human transmission. The aim of the present study was to verify whether dogs and cats act as passive mechanical carriers of SARS-CoV-2 when they live in close contact with COVID-19 patients. Cutaneous and interdigital swabs collected from 48 dogs and 15 cats owned by COVID-19 patients were tested for SARS-CoV-2 by qRT-PCR. The time elapsed between owner swab positivity and sample collection from pets ranged from 1 to 72 days, with a median time of 23 days for dogs and 39 days for cats. All samples tested negative, suggesting that pets do not passively carry SARS-CoV-2 on their hair and pads, and thus they likely do not play an important role in the virus transmission to humans. This data may contribute to confirming that the direct contact with the hair and pads of pets does not represent a route for the transmission of SARS-CoV-2.
