Myiasis means fly disease. The flies' larvae can feed on the host's living or dead tissue, liquid body substance, or ingested food.

When the tissues in the oral cavity are invaded by parasites, this is known as oral myiasis. 

Those at risk of the rare condition include those from poorer social backgrounds and people who have suffered wounds or other injury to the face.

It is also more common in regions with a warmer climate. 

Infestations of the nose and ears are dangerous because of the possibility of penetration into the brain, the fatality rate is 8 per cent in such cases.
