No. Viruses from humans cannot be carried by dogs or other pets, except in very extreme cases. Stastically speaking it doesn’t happen and it’s not something to worry about.

Rabies, influenzas, haemorrhagic fevers, West Nile, coronaviruses, and Zika might like to have a word with you on the subject.

  Rabies is one of millions of viruses, it’s very very rare for a new virus to jump from one host species to another new species. Covid 19 already jumped from bats to people, it would need to mutate again to survive in a pet and spread via that vector.

    Rabies is one of many viruses, but one of relatively few that cause disease in humans. From the NY Times the other day: https://www.nytimes.com/2020/03/24/science/viruses-coranavirus-biology.html https://www.nytimes.com/2020/03/24/science/viruses-coranavir...

    > Covid 19 already jumped from bats to people, it would need to mutate again to survive in a pet and spread via that vector. I don't see it as unreasonable to think that if it can cross from one mammal to another mammal, that makes it more likely to be able to cross to a third mammal. To make the crossing from bats to humans, it has to be doing something that works in both bats and humans, exploiting some feature that is common to both. But a feature common to bats and humans is much more likely to be also shared with dogs than a feature that humans have and bats don't. This is the same principle that tells us that while it's rare for a virus to cross from infecting bats to infecting humans, it's much, much rarer for one to cross from infecting grasshoppers to infecting humans.

      There's an interesting manuscript (caveat emptor) I found related to this[1] that states: "2019-nCoV RBD likely recognizes ACE2 from pigs, ferrets, cats, orangutans, monkeys and humans with similar efficiency, because these ACE2 molecules are identical or similar in the critical virus-binding residues." Not being a biologist or virologist, I don't know how true this is, but it may suggest this incident with the cat did in fact happen.

Wonder how long the virus can survive on the fur of a pet. This is very different than the animal being infected and becoming a production factory for a virus but if we're being cautious about spreading the virus through contact with shared objects, pets seem like they could be a vector for a period of time. Perhaps a day or two?

  The observation is sound. And also note that pets may be much more likely than (adult) humans to go into contact with some things and areas contaminated by saliva. As for the stability, unless fur is more hostile than plastic or stainless steel, detectable viable virus at 72 hours is indicated in this recent article by van Doremalen et al. https://www.nejm.org/doi/10.1056/NEJMc2004973 https://www.nejm.org/doi/10.1056/NEJMc2004973 Experience from other coronaviruses, including SARS-CoV-1 and MERS-CoV, shows even longer persistence for some surfaces and environmental conditions.
