6. Ebola

Ebola

Ebola is responsible for a severe and often fatal viral hemorrhagic fever. It has been named after the Ebola river in Africa, from where it is said to have originated in 1976. Ebola is a virus of the Filoviridae that cause epidemic human disease. The disease is characterized by extreme fever and profuse haemorrhaging. Extensive research is being conducted to find an antidote for this lethal disease, but the disease is still incurable in 2013 with a fatality rate of 90% for humans.

 

7. Asthma

Asthma

Asthma is a chronic lung disease in which inflamed airways become swollen and extremely sensitive. Asthma causes recurring episodes of wheezing, chest tightness, coughing, breathlessness that may range in severity. Generally coughing occurs either at night or early in the morning, but the airways become hypersensitive to a variety of stimuli like pollen, air pollution, smoke, weather conditions, and exercise.

During the process of breathing, the muscles around the airways rhythmically expand and contract. While contracting, the airways get narrower which causes less air to flow into the lungs. The swelling determines the severity as it worsens the condition. This recurring reaction can result in asthma symptoms that take place each time the airways are inflamed. Asthma affects people of all ages, but about half of all cases occur in persons younger than 10 years of age.

 

8. Diabetes

Diabetes

However common it may sound, though Diabetes is not lethal, it is incurable. Diabetes is a chronic disorder of the carbohydrate metabolism that affects the role of hormone insulin in the body and consequently it is characterised by high levels of sugar in the body. Diabetes generally occurs in two forms: Type1 and Type2.

Type I diabetes, which is insulin-dependent diabetes mellitus (IDDM). Here, the diabetic person is required to take hormone injections daily as it affects the ability of pancreas in the body to produce insulin. The most common form of diabetes is Type2 diabetes which is the non-insulin-dependent diabetes mellitus (NIDDM). In this, the body fails to work in coherence with insulin—which is responsible for monitoring the storage of glucose in the body. As a result, the high blood-sugar level triggers the pancreas to increase the insulin production to keep up with the increased sugar in the body. This condition generally develops in overweight people, however it may also occur to the elderly.

 

9. Creutzfeldt-Jakob Disease

Creutzfeldt-Jakob Disease

Creutzfeldt-Jakob disease (CJD) is a rare, degenerative and fatal disease of the central nervous system. The disease was first spotted by German neurologists HG Creutzfeldt and AM Jakob, and thus the name. The disease usually is characterized by vague psychiatric or behavioural changes, followed by progressive dementia accompanied by abnormal vision and involuntary movement. With time, mental deterioration is prominent and involuntary movements, blindness and coma may occur. The disease commonly occurs in adults between the ages of 40 and 70, and is fatal within a year in almost 90% of the cases. There is no known cure for the disease till date.

 

10. Polio

Polio

Poliomyelitis, commonly known as Polio is an acute infectious viral disease that affects the nervous system. Polio that may lead to partial or full paralysis, usually begins with common symptoms like headache, nausea, fever, fatigue, and muscle pains. The polio virus may enter the bloodstream but only in about 1% of the cases, the virus may attack the central nervous system. Polio cases across the globe occur in children especially below the age of five. Depending on the nerves targeted by the poliovirus, different types of polio may occur that include cord, bulbar and bulbospinal polio.

Polio vaccination is one of the most important vaccinations given to children, but as far as cure is concerned, Polio is incurable. The widespread awareness about polio vaccines has eliminated the disease from many countries but it continues to paralyse a substantial number of children in the African and South Asian countries.
