From farmed mink to your pet cat, here's what we know about coronavirus and animals

(CNN)The planned slaughter of almost 100,000 mink after a coronavirus outbreak on a Spanish farm has renewed questions around Covid-19 and the transmission to animals.

While the US Centers for Disease Control and Prevention (CDC) says there's no evidence that animals play a significant role in spreading the virus, there have been reports of pets being infected.
And since the coronavirus is believed to have infected wild animals before jumping to humans, this is an area scientists need to learn more about in an effort to control the spread of Covid-19 and future illnesses.

    Can animals catch coronavirus?

      An infected mink farm in Deurne, the Netherlands, on June 6 as animals were culled on 25 farms.
      The coronavirus has been identified on at least 25 mink farms in the Netherlands, according to the country's government, which said on Friday that it had culled animals at 24 infected farms.
        Covid-19 was found in three of 11 cats at one mink farm, and the government said cats may play a role in the spread of the virus between farms.
        At a farm in Teruel, Spain, 92,700 mink are to be culled after 78 of 90 animals tested were found to have the coronavirus -- 87% of the sample.
          There have also been reports of pet cats and dogs infected with the virus in several countries, including New York, Hong Kong and the Netherlands. Eight big cats tested positive at New York's Bronx Zoo.

          Can I catch coronavirus from my pet?

          The CDC says the risk of animals spreading Covid-19 to people is "considered to be low" and the agency does not recommend routine testing of pets.
          A YouTube video released by the US Food and Drug Administration (FDA) in mid-June said that "it doesn't seem like animals can give you the virus," although you may be able to give it to them.
          However, Dutch authorities said it was "plausible" that a mink may have infected a human with Covid-19, and instituted mandatory testing of animals at all mink farms in the Netherlands.
          Since animals can spread other diseases to humans, it's always best to wash your hands after touching a pet and before touching your face.

          Didn't the coronavirus originate in wild animals?

          Researchers believe the coronavirus spent some time infecting both bats and pangolins before it jumped into humans. Scientists suspect humans first came into contact with an animal sick with the disease at a wet market in China.
          But scientists say a third species of animal may have played host to the virus before it spilled over to people.
          What is clear is that the coronavirus has swapped genes repeatedly with similar strains infecting bats, pangolins and a possible third species, a team at Duke University, Los Alamos National Laboratory and elsewhere reported in the journal Science Advances in May.
          What's also clear is that people need to reduce contact with wild animals that can transmit new infections, they concluded.
