Modern medicine has done much to eradicate and cure disease, but it has failed in some areas. Of those areas, at least one disease that cannot be cured is suffered by many people in the world every year - the common cold.
The following is a list of the top ten incurable diseases.
10. Ebola
Ebola is a virus of the family Filoviridae that is responsible for a severe and often fatal viral hemorrhagic fever; outbreaks in primates such as gorillas and chimpanzees as well as humans have been recorded. The disease is characterized by extreme fever, rash, and profuse hemorrhaging. In humans, fatality rates range from 50 to 90 percent.
The virus takes its name from the Ebola River in the northern Congo basin of central Africa, where it first emerged in 1976. Outbreaks that year in Zaire (now Congo [Kinshasa]) and The Sudan resulted in hundreds of deaths, as did another outbreak in Zaire in 1995. Ebola is closely related to the Marburg virus, which was discovered in 1967, and the two are the only members of the Filoviridae that cause epidemic human disease. A third related agent, called Ebola Reston, caused an epidemic in laboratory monkeys in Reston, Virginia, but apparently is not fatal to humans.
9. Polio
Polio is known in full as poliomyelitis - also called infantile paralysis. It is an acute viral infectious disease of the nervous system that usually begins with general symptoms such as fever, headache, nausea, fatigue, and muscle pains and spasms and is sometimes followed by a more serious and permanent paralysis of muscles in one or more limbs, the throat, or the chest. More than half of all cases of polio occur in children under the age of five. The paralysis so commonly associated with the disease actually affects fewer than 1 percent of persons infected by the poliovirus.
Between 5 and 10 percent of infected persons display only the general symptoms outlined above, and more than 90 percent show no signs of illness at all. For those infected by the poliovirus, there is no cure, and in the mid-20th century hundreds of thousands of children were struck by the disease every year. Since the 1960s, thanks to widespread use of polio vaccines, polio has been eliminated from most of the world, and it is now endemic only in several countries of Africa and South Asia. Approximately 1,000–2,000 children are still paralyzed by polio each year, most of them in India.
8. Lupus Erythematosus
Also often referred to simply as lupus, this is an autoimmune disorder that causes chronic inflammation in various parts of the body. Three main types of lupus are recognized—discoid, systemic, and drug-induced.
