If we’re talking worms, then we’re talking parasites – small intestinal parasites, to be precise. It sounds hideous, but the threadworm (or ‘pinworm’) is the most common worm parasite infestation of children in the UK (although, any age can be affected). They are usually passed on through poor hygiene, live about 5-6 weeks in the gut, and then die. But before doing so, the female worms lay tiny eggs around the anus, which leads to itching during the night. The resultant scratching can lead to eggs getting onto our fingers and under our nails, which we may then swallow, beginning the cycle of infestation again. However, threadworms can usually be eradicated with medication and strict hygiene. But if you think humans have it bad, then you should consider grasshoppers, who play host to ‘hairworms’ which essentially brainwash the insects with a cocktail of chemicals that makes them commit suicide by leaping into water. In light of that – an itchy bottom is nothing!
