New series The average person has around one million parasites living on or in them. The first of three programmes hears from victims of squirm-inducing parasite encounters, meeting a woman who's found a maggot living in her scalp and a biologist who's voluntarily playing host to a three-metre tapeworm in his intestine. Ross Kemp narrates.
