Just a side note, in the medical field, we know that usually catastrophes happen when you are not aware, take the example of tetanus a deadly disease yet easy to prevent, because vaccination is done in childhood and repeated every ten years, everyone is protected yet the medical personnel always verifies immunization status for every wound just because the disease is deadly yet easy to prevent, with that we still have cases of tetanus and guess what's the most frequent cause ? it's roses spikes 

Why ? people never suspect getting tetanus from a rose spike and don't seek treatment...
