Can animals spread Covid-19 to people?

This is not the very first mink farm to have observed a coronavirus outbreak. In May, Dutch authorities launched necessary tests at all mink farms in the Netherlands soon after they reported they believed a mink could have contaminated a human with Covid-19.

The tests has led to the culling of up to a single million mink in the state at two dozen farms, according to animal welfare charity Humane Society Global.

“On the foundation of new study effects from the ongoing exploration into Covid-19 infections at mink farms, it is plausible that an an infection took area from mink to human,” the Dutch governing administration stated in a assertion at the time. “It also seems from this exploration that minks can have Covid-19 devoid of exhibiting indications.”

The Dutch authorities also reported it believed cats may perform a role in the distribute of the virus in between farms. “Ongoing analysis displays the viruses at two of the contaminated farms are quite equivalent,” the assertion mentioned. Covid-19 was observed in three out of 11 cats at a single mink farm, it claimed.

The virus has been viewed in a wide variety of other animals, together with a amount of tigers in New York’s Bronx Zoo in April and a dog in Hong Kong.

In accordance to the Globe Health Group, whilst it is not feasible to identify exactly the resource of the virus, it most likely originated in bats. Nevertheless, much more analysis requires to be carried out to identify how the virus perhaps spreads from animals to humans as the function animals enjoy in the spread of the virus continues to be unclear.
