This article goes into more detail. I think it is horrible the way they killed 102 animals over a virus that is harmless to the animals and to ordinary people.
"The virus usually causes little or no illness in healthy people" (above)
People need to learn to practice basic hygiene like washing one's hands after using the bathroom and before eating (among the general public, this practice is not common).
The human immune system is an important part of our bodies, a healthy immune system fights off many attempts at infection every day. So of course there is a great risk of otherwise harmless infections becoming lethal when the immune system is supressed by drugs or other methods. It may as well have been e.coli or a common phage virus, rodents aren't the actual cause of death here -- the supressed immune system is.
From the article above:
"Gail Mastrati, a spokeswoman for the state Department of Environmental Management said the agency removed 102 hamsters, mice and guinea pigs from the store in the past week. The animals were euthanized and shipped to the CDC in Atlanta, where all will be tested. Preliminary results indicate two of the hamsters sent Friday to the CDC tested positive for LCMV, she said. The CDC would not confirm the results."
Why did they euthenize the guinea pigs? Those guinea pigs at least deserved a chance at being adopted into a good, loving home.
