Case study Sandymount Road -Rats

You are right about the relative frequency of Weil's in Ireland. However, if you are the one who gets it and dies you are 100% dead

In 1996 there was a case of an adult golfer who contracted it from a rat on the course. He died of kidney failure. Link https://www.irishtimes.com/news/public-warned-as-rat-infection-kills-dublin-man-1.81306

My approach to these matters is to be risk aware but to keep a sense of proportion. Once aware of a danger I prefer to be cautious especially where I am responsible for other peoples lives.
