Rare diseases in Africa
Modern medicine has done much to erradicate 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. This is a list of the top ten incurable diseases. As always, click the images for a larger view. NOTE: There are no graphic images in this post.
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.
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.

Blood oranges in Africa just fyiby April161990
Surely one of the oddest legends to emerge at the dawn of the New South Africa was the AIDS in the orange legend. This legend almost brought the entire citrus industry in South Africa to its knees. In July 1993 rumours hit the cities that oranges had been infected with HIV-positive blood. These rumours contained elaborate plots, mainly centring around the right wing. Firstly, it was widely believed that a right-wing Natal farmer had sprayed his orange crops with his own Aids-infected blood. Secondly, the myth went that an AWB supporter had injected his labourers infected blood into oranges
And it isnt really that 'forest clearing' per se causes the problem, its said to be a problem with people doing work where the following happens. I'm not sure I buy it, but I havent had time to do the research on this one.
The argument, I think, goes like this.
1. Inter-specific transfer of diseases is rare but is bad (it is, no question). Diseases that have been around in a species for a while tend not to be too bad; the vulnerable hosts have died, and the disease itself tends to evolve to be less deadly (kill the host, and you cant transmit your progeny to another host). Newly arived diseases tend to be deadly
