Scientists Say Worms Can Cure Diseases

Scientists are pushing for the return of parasitic worms to treat major illness, like asthma and multiple sclerosis.

How it works: scientists plan to infect asthma sufferers with hookworms, by placing them on the patient's skin and allowing them to burrow their way into the body (this process can ease patients' symptoms); an Argentinian study showed that infecting multiple sclerosis sufferers with parasites slowed the progression of the condition.

The scientists say the prevalence of other allergies could be a reaction to the absence of worms.

Professor Jan Bradley, an expert in parasite immunology at Nottingham University, said our immune systems could be "out of balance" because of a lack of the parasites.
