1American zoos are taking steps to protect their animals from catching the new coronavirus from humans.
2The steps include many of the same measures used to slow the spread of the virus in humans.
3These include social distancing and cleaning shared equipment.
4Vaccines have also been used on animals.
5At the San Diego Zoo, a female orangutan became the first ape in the world to get a coronavirus vaccine in January.
6The vaccine was given after a group of gorillas started showing signs of infection and later tested positive for the coronavirus.
7The orangutan, named Karen, received two shots of a vaccine made by Zoetis, a New Jersey company that manufactures drugs for animals.
8Nine other primates at the San Diego Zoo have been fully vaccinated: five bonobos and four orangutans.
9Four more animals -- one bonobo and three gorillas -- got their first shots this month and will get a second in April.
10Nadine Lamberski is the wildlife health officer for the San Diego Zoo.
11She told the Associated Press that zoo officials acted quickly to vaccinate the animals in an effort protect other great apes.
12The outbreak was linked to a zookeeper who was infected but had no signs of the virus.
13Seven gorillas got minor cases and recovered.
14But one older silverback gorilla developed the lung disease pneumonia, likely caused by the virus, as well as heart disease.
15He was put on medicines and received an antibody treatment to block the virus from infecting cells.
16About 36 zoos in the United States and other countries have placed orders for the Zoetis vaccine.
17It is meant to work on particular animal species.
18"We will jump at the opportunity to get the Zoetis vaccine for our own great apes," said Oakland Zoo official Alex Herman.
19She is ordering 100 injections.
20Zoetis got permission from the U.S. Department of Agriculture to provide the vaccines on an experimental basis to the San Diego Zoo.
21The company will need to seek the same permission to provide the shots to additional zoos.
22Scientists believe the new coronavirus likely started in bats before jumping to humans.
23Now many researchers worry that humans may unknowingly infect other animal species.
24Animal health experts say great apes such as gorillas are especially at risk of becoming infected.
25These animals share 98 percent of their DNA with humans.
26So far, confirmed coronavirus cases include gorillas, tigers and lions at zoos; domestic cats and dogs; farmed mink, and at least one wild mink in Utah.
27Scientists have also experimentally shown that ferrets, racoon dogs and white-tailed deer are at risk, although pigs and cows are not.
28Another concern is that virus spread among other species could produce new versions, or variants.
29In Denmark, workers at a mink farm unknowingly infected the animals.
30As the coronavirus spread among the mink, it mutated and humans became infected with the new variant.
31In an effort to control the situation, the government ordered millions of mink to be killed.
32Scott Weese is a microbiologist at Ontario Veterinary College in Canada.
33He told the AP that "mutations happen when there's a lot of disease transfer going on between animals."
34Since the outbreak, the San Diego Zoo has been using a lot of fans at its indoor primate areas to improve air flow.
35Zoo workers also wear face coverings and limit their time spent inside with the animals.
