Parasitic worms found in woman’s eye as scientists warn of ‘emerging’ disease

A parasitic worm typically found in cattle has been discovered in a woman's eye in what scientists have warned may be an "emerging zoonotic disease" in the US.

The 68-year-old woman is the second human to have become infected by the parasite.

The scary experience led the woman to seek help from an eye doctor. There, the doctor removed the roundworm from her eye.
