The mother of a toddler whose death at the the Royal Hospital for Children in Glasgow, Scotland, claims she has documents which show that bacteria was found on the showerhead in her son's bathroom, according to an article on the Evening Times website.
The death of a three-year-old boy in 2017 is being investigated.
His death came in the same month as that of a 10-year-old who was in remission from leukemia before contracting an infection at QEUH which her mother believes was water based.
NHS Greater Glasgow said the three-year-old boy's death was "fully investigated."
