Social distancing is not a new concept in the natural world, where infectious diseases are commonplace. Through specialized senses animals can detect certain diseases and change their behavior to avoid getting ill.
In 1966, while studying chimps (猩猩) in a Tanzanian national park, zoologist Jane Goodall observed a chimp named McGregor who had caught a highly infectious virus. His fellow chimps attacked him and threw him out of the troop. In one instance, McGregor approached chimps in a tree. He reached out a hand in greeting, but the others moved away without a backward glance.
“For a full two minutes, old McGregor sat motionless, staring after them,” Goodall notes in her 1971 book In the Shadow of Man. “It’s really not that different to how some societies react today to such a tragedy.”
Not all animals are so aggressive toward their ailing neighbors. Sometimes it’s as simple as avoiding those who may infect you.
When Kiesecker, a lead scientist in America, studied American bullfrog in the late 1990s, he found that bullfrogs could not only detect a deadly smell of infection in other bullfrogs, but healthy members actively avoided those that were sick. Bullfrogs rely on chemicals signals to determine who is sick or not.
Caribbean lobsters also shun diseased members of their community, well before they become infectious. It takes about eight weeks for lobsters infected with the deadly virus Panulirus argus mininuceovirus to become dangerous to others. Normally social animals, lobsters begin keeping away from the diseased as early as four weeks after infection – once the lobsters can smell certain chemicals released by sick individuals.
Overall, it’s important to note that, unlike us, animals don’t realize if they stay home, they might actually reduce the infection rate,” Kiesecker explains. “As humans, we have that ability. It’s a big difference.”
