Well as we have discussed before the HSE / NPHET are just making up shit. We are talking an organization that cant be bothered to even keep tabs on the number of Influenza deaths per annum, has no numbers of how many people died from Swine Flu (H1N1) in 2009/2010, and it looks like their HAP/HAI numbers are based on sending out questionnaires to hospitals.
Now the CSO have issues of their own. The great Leprechaun Economics fiasco when they finally moved to EUROSTAT methodologies been a good example. But if the CSO says it’s one number and the HSE says it another you can be pretty sure that the CSO number is actually based on real world data that can be verified whereas the HSE data is mostly pulled out some middle managers arse by the sound of it.
