A mum has said doctors were left stunned when her sick baby tested positive for potentially-deadly typhoid fever.
Tanya Johnson said she knew something was seriously wrong with her 12-month-old daughter when her condition kept deteriorating and medics were struggling to come up with a diagnosis, at first believing it to be a viral infection.
But the mum-of-four said the poorly youngster was later found to have typhoid fever, which is caused when someone becomes infected with the salmonella typhi bacteria.
