Health officials in Ireland claim there were only four cases of Lyme disease in their country last year.

Dr. Jack Lambert, a professor of infectious diseases at University College Dublin’s School of Medicine, vehemently disagrees.

In a recent segment on The Pat Kenny Show, an Irish radio talk show, Lambert estimated there were at least 2500 cases.

“I think the diagnosis is being missed all the time, because people said ‘You never saw a tick.’ A tick is the size of a sesame seed – you might never see a sesame-sized tick on the back of your leg.

“Half the people don’t get the rash that’s classic for it, they might just get kind of flu-ish. And the antibody testing is not 100% – so I think the numbers that are reported to the HSE [health officials] are just the tip of the iceberg. There’s a lot more patients in Ireland with this condition.”
