Mad Cow Disease is a disease that can infect animals and humans. If it infects a cow, the disease is known as bovine spongiform encephalopathy, while in humans it is known as variant Creutzfeldt-Jakob disease.

6. Cirrhosis

Cirrhosis is the result of long-term chronic scarring and liver damage. The damage may be due to kidney disease or it could be due to chronic hepatitis and alcoholism.

The liver functions to filter harmful substances from the blood and send them throughout the body. When the liver is damaged, harmful substances will cause scar tissue to form. If that happens then the liver has to work hard to function properly.

7. Noma (Cancrum Oris)

Noma or usually known as Cancrum Oris is an infection that causes ulcers to form in the mouth or on the genitals. These boils that were previously visible to the naked eye can "move" into the body's tissues until they no longer appear, causing defects from within the body.

Life expectancy from this deadly disease is small. Nearly 90 percent of people who develop Noma eventually die from complications of the infection.

Noma generally occurs in malnourished children in areas with poor sanitation and hygiene. This infection is most common in children between the ages of 2 and 5 years.
