After deposition in environment, eggs get develop into infection within 2 to 4 weeks and may survive the soil for few years. If such infectious eggs accidentally get swallowed by the humans, their larvae get hatched out of these eggs and can move inside body organs resulting in serious disease. The infections show the symptoms in humans depending on amount of eggs ingested in body and where they have gone like in eye, brain, liver or kidneys. The symptoms like tiredness, loss of muscular control, coma, blindness and lack of coordination may occur.
