Some animal activists say an elephant performing in Baltimore with the Ringling Bros. and Barnum & Bailey Circus is a public health risk because it tested positive for tuberculosis, but circus and public health officials say the animal doesn't have an active form of the disease and isn't a danger. Federal rules call for quarantines only when infected elephants have active cases, but Karen the elephant was previously banned from entering Tennessee, a state where nine animal refuge employees caught TB from an infected elephant.
