flu virus

Humans are particularly generous with the flu, otter-wrangling scientists have found.

People shared the 2009 swine flu epidemic with ferrets, dogs, cats, raccoons and pigs, and new research shows even wild sea otters in Washington state got hit. 

"These otters, which we think were living in a relatively pristine environment off the Olympic Peninsula, were exposed to pathogens that are more commonly associated with people," said Virologist Hon Ip with the U.S. Geological Survey, who co-authored the study published in the May 2014 issue of “Emerging Infectious Diseases.”
