PODOCONIOSIS

Podo (or podoconiosis, from the Greek for 'foot' and 'dust') is a non-infectious type of elephantiasis. It is also called 'Mossy Foot' (because the skin changes look like moss) or 'verrucosis lymphatica'.
2. What causes the disease, and who discovered it?

3. How does podo differ from elephantiasis?
Podo (or to give it its full name, podoconiosis) is one type of elephantiasis.
4. In which countries are there confirmed or suspected cases of podo? Why focus on Ethiopia?
Podo has been confirmed in eight countries in tropical Africa, and is thought to occur in several other countries in the tropics, including in Central America and northern India. The focus on Ethiopia has arisen because of the heavy load of podo – one million people (out of a population of around 80 million) are affected.

An estimated 4 million people have podo worldwide.
6. Why have so few people heard of podo?
Podo is truly a disease of the voiceless – it only affects people in rural communities who are too poor to afford shoes. It is also neglected because it is a tropical disease that visitors to the tropics will never develop, unlike, for example, malaria.
7. How much exposure to the soil is required to get podo? Are kids more susceptible for any reason?
Several years’ exposure to irritant soil is needed. Shoe wearing habits during childhood may be particularly important, since the skin of the feet is soft at this age.
8. Can people walk with this disease or is it paralyzing?
People can walk in the early stages of podo, but often feel aching discomfort as they walk. In the later stages of disease, it may become impossible to move because of the weight of the swollen leg.

If the disease is treated early, the patient can regain a normal foot and leg if she or he follows a careful, lifelong program of foot hygiene and wears socks and shoes throughout waking hours. Patients with advanced disease show great improvements if they follow the same program, but it may be difficult to get back to a normal-looking foot. The aim for these patients is that the disease is controlled such that they can wear normal shoes, earn a living, and be accepted back into their society.

People with podo are often badly treated in many ways. Children and youth with podo get chased out of school, adults are shunned and find it difficult to participate at church or mosque.
11. How effective can shoes be in preventing podo?
Because podo has vanished from parts of the world where irritant soil exists and where shoe wearing is the norm, we assume that shoes are highly effective in preventing podo.
12. Where do you see podo in 5, 10, or 20 years?
If everyone living on irritant soil had access to shoes, podoconiosis could be a thing of the past in only 20 years. This sounds simple, but helping communities understand the importance of shoe wearing, and actually delivering shoes to them are huge tasks.
13. What actions would help podo gain more visibility among health organizations?
Awareness of podo must be increased at every level – affected communities, local organizations, national governments, NGOs, and international bodies. Podo needs not just a stronger scientific basis, but engagement across disciplines, from ethics to literature, law, IT and economics
