Since 1990 - 1996 there have been 85 cases of Weil's disease in humans. Whilst it is possible for foxes to carry the infection their role in human disease is likely to be very small if at all. Dr. Robert Smith at CDSC could not recall any cases with which foxes were known or thought to be associated. Toxacariasis Transmission to humans is through ingestion of viable eggs from contaminated faeces. Eggs require 10 - 14 days maturation in soil before they become infective and are killed by desiccation.
Human cases can range from a symptomatic infection to eye infection.
Humans are not carriers and infection is treatable once identified. Simple hygiene precautions such as worming both cats and dogs regularly and the disposal of their faeces by burning or throwing in the garbage. Whilst Canine Mange, often wrongly called fox mange can bring out an allergic reaction in people, the mite needs specific hosts to feed and breed on. If dogs come into contact with mange they can usually be easily treated at the vets. Problems Fouling One of the most common complaint we receive is from people wanting advice on how to discourage foxes from fouling on their lawns and digging up the flower beds.
