    <div>The data is all over the place on dogs and SARS-CoV-2 infection.</div><div>

    “A three-month-old Connecticut puppy that died unexpectedly tested
    positive for the virus that causes COVID-19, UConn researchers announced
    Tuesday. The dog was the first domestic animal in the state to test
    positive for the coronavirus…”


    A recent study suggests that dogs spread coronavirus but CDC has not updated thier webpage to match this information.


    Are Dogs Spreading SARS-CoV-2? Study Finds Living With a Dog Increases Risk of Contracting COVID-19



    Study based on 2,086 individuals

    This study, carried out throughout Spain, sought to shed light on other possible routes of transmission of the COVID-19 disease, risk factors, and the effectiveness of the hygiene measures recommended by the Authorities, in order to detect critical points of exposure to the virus and thus minimize its spread—not only in this pandemic but also for any future events that could compromise public health.

    Based on a sample of 2,086 individuals, 41% of the population surveyed were aged between 40 and 54 years and had studied to degree (44%) or postgraduate (32%) level. This collective presented a prevalence of the disease of 4.7%.

    The results showed that the risk of suffering from COVID-19 is 60 times higher among those who cohabit with a COVID-19 patient. In addition, of all the socio-demographic variables analyzed, the one with the most powerful effect in terms of increasing the risk of contracting the disease (by up to 78%) was living with a dog and taking it for a walk. By contrast, having cats or other types of pets had no significant effect on the prevalence of the disease.

    “The results of our research warn of increased contagion among dog-owners, and the reason for this higher prevalence has yet to be elucidated. Taking into account the current scarcity of resources to carry out the diagnosis of SARS-CoV-2 in humans, the possibility of diagnosis in dogs is extremely unlikely,” notes Sánchez González.

    These results point to cohabiting with dogs as being a strong risk factor for COVID-19 infection, although further studies are needed to determine whether the reason for this sharp increase in the risk of SARS-CoV-2 infection is due to transmission between humans and dogs, to the dog acting as a vehicle for the virus, or to the increased contact with other vehicles for the virus (that is, objects or surfaces where the virus is present). The latter could be caused by greater exposure to the virus due to the unhygienic behaviors and habits of dogs when out in the street and their subsequent return to the home.

    “At the international level, there are several studies that have obtained results similar to ours regarding Coronavirus infection in dogs, but it is necessary to dig deeper on this issue and establish whether this prevalence of the virus among dog-owners is due to one reason or another,” explains the UGR researcher.

    Sánchez González warns that, “in the midst of a pandemic and in the absence of an effective treatment or vaccine, preventive hygiene measures are the only salvation, and these measures should also be applied to dogs, which, according to our study, appear to directly or indirectly increase the risk of contracting the virus.”

    The researcher also points out that “from a scientific point of view, there is no justification for children’s playgrounds being closed to prevent infections while parks, where dogs are walked, are allowed to remain open, when there are numerous objects there that can act as vehicles for SARS-CoV-2. At the same time, we should not rule out the possibility that the virus may be transmitted via fecal matter.” […]

    From the American Kennel Club:

    According to the Centers for Disease Control, “there is no evidence that
    pets play a role in spreading the virus in the United States.
    Therefore, there is no justification in taking measures against
    companion animals that may compromise their welfare.”

    Dogs Can Now Get COVID-19: How to Keep Your Pet Safe

    Recent research
    has shown that not only can dogs get infected by the virus. In some
    cases their fur can also serve as a carrier of the virus, thereby
    risking even your life. Thus, both you and your dog are at risk from the




    Updated Mar. 25, 2021

    “At this time, there is no evidence that animals play a significant role
    in spreading SARS-CoV-2, the virus that causes COVID-19, to people.”

    “Based on the available information to date, the risk of animals spreading COVID-19 to people is considered to be low.”

    Discrimination of SARS-CoV-2 infected patient samples by detection dogs: A proof of concept study


    While the world awaits a widely available COVID-19 vaccine, availability of testing is limited in many regions and can be further compounded by shortages of reagents, prolonged processing time and delayed results. One approach to rapid testing is to leverage the volatile organic compound (VOC) signature of SARS-CoV-2 infection. Detection dogs, a biological sensor of VOCs, were utilized to investigate whether SARS-CoV-2 positive urine and saliva patient samples had a unique odor signature. The virus was inactivated in all training samples with either detergent or heat treatment. Using detergent-inactivated urine samples, dogs were initially trained to find samples collected from hospitalized patients confirmed with SARS-CoV-2 infection, while ignoring samples collected from controls. Dogs were then tested on their ability to spontaneously recognize heat-treated urine samples as well as heat-treated saliva from hospitalized SARS-CoV-2 positive patients. Dogs successfully discriminated between infected and uninfected urine samples, regardless of the inactivation protocol, as well as heat-treated saliva samples. Generalization to novel samples was limited, particularly after intensive training with a restricted sample set. A unique odor associated with SARS-CoV-2 infection present in human urine as well as saliva, provides impetus for the development of odor-based screening, either by electronic, chemical, or biological sensing methods. The use of dogs for screening in an operational setting will require training with a large number of novel SARS-CoV-2 positive and confirmed negative samples.

    <b itemprop=”headline”> UW study finds COVID virus in dogs, no public health risk

    According to the department, 23 samples tested positive for antibodies to SARS-CoV-2.

    “We only have antibody test positive results at present, so we cannot say much about the risk between dogs or from dog to human — we don’t have evidence of this yet,” said Peter Rabinowitz, director of UW’s Center for One Health Research, which studies the health links between humans, animals and their shared environments. “But we want to keep studying the problem to get more evidence.”

    Cat antibody tests are still in process, Rabinowitz said.

    “The fact that dogs are turning up positive in our study indicates that human to pet transmission of COVID can occur and people infected with COVID should take precautions such as masks, distancing, and hand washing, to protect both other people and pets,” he said.

    These are the first cases of a pet testing positive in Washington, but not the first in the U.S., as there have been numerous reports nationally of companion animals testing positive for SARS-CoV-2, according to WSDA.

    The Washington State Department of Health recommends that people who are
    ill with COVID-19 and in home isolation avoid direct contact with pets.
    If possible, a household member should care for pets in the home. If a
    person with COVID-19 must care for pets or other animals, they should
    wear a mask and wash their hands before and after interacting with them.

    Findings show that human-to-animal SARS-CoV-2 transmission in households is quite common

    The findings indicate that the transmission of SARS-CoV-2 from human-to-animal in households is common in a study population with close human-animal contact. They also show that infected pets often show signs of COVID-like disease.
