Before I allow Professor Nolan to add something, if he wishes to do so, there are some anomalies in terms of outbreaks. The counties of Cavan and Monaghan have had fairly high instances, proportionally. I think Cavan has the highest, Monaghan the third highest. The reason many people find this unusual is that, internationally, it appears that the greatest concentrations of cases are generally in large urban centres. I think that in most countries the epicentres are generally in large cities. Cavan and Monaghan are two predominantly rural counties. Does Dr. De Gascun have any understanding or reasoning as to why these counties have had such high instances?
