The single case of Porcine Epidemic Diarrhea virus found near London pales in comparison to the continuing spread across the United States.
Federal officials say 122 more farms were added last week, bringing the total to 2,394 barns in 23 states since the first case was identified in Illinois in April.
Iowa remains the hotbed with 882 cases.
Although the precise source of the London outbreak has not been revealed, it’s almost certain to be a truck or person returning from the United States.
The virus survives longer in cold weather.
