Wormplague

Wormplague is a parasitic infection where the body breaks out in thousands of maggots, reproducing faster than the body can destroy. It is resistant to magical curing, as spells are unlikely to fully eradicate all of the worms in one's body. It is more commonly spread during the harsh winter months when the body is weaker, especially while food is being rationed. It is additionally believed that Dulleyes are helping to spread the infections, because they don't take precautions to avoid getting infected nor avoid infecting others.
