Reacción a "Reaction to the closure of a farm in Toledo due to the suspected first autochthonous case of cholera in Spain since 1979"

We are talking about non-potable, non-chlorinated water, without any hygienic control. I am curious about the source of the initial contamination, about how the Vibrio [a genus of bacteria] got there. We will have to wait for the epidemiological investigations that are already underway. If it had been cholera, the risk of a wider outbreak in Spain, with the control and prevention of drinking water and environmental sanitation, would have been almost non-existent.
