Speaking of plexi-glass barriers, I saw this on whitetail deer study;
First, in a laboratory study, researchers spritzed four fawns’ noses with infectious coronavirus to test whether the virus could infect them. They also took two uninfected deer into the same room, keeping them separated with a plexiglass barrier that didn’t reach the ceiling.
“We had four inoculated animals and two contact animals. Everybody got infected and shed significant amounts of infectious virus. That was a surprise,” said Diego Diel, an associate professor of virology at Cornell University, who helped lead the research.
The deer most likely shared the virus through nasal secretions that traveled over the barrier by air, he said. The infected deer didn’t exhibit noticeable symptoms.
