Progress in the medical world every day more rapidly. But there are still some diseases and viruses that remain a mystery to doctors and scientists around the world. Besides HIV, there are some diseases that until now still can not be cured permanently. Here some diseases do not have the cure.
Polio
Poliomyelitis, better known as Polio, has been around for thousands of years. It is an acute infectious viral disease that affects the nervous system. Usually affects the feet and causes paralysis. In most cases, the first symptoms are headache, nausea, fever, fatigue and muscle aches.
It usually spreads through contaminated food and water, and the disease manifests itself especially in children under the age of five. Today, large numbers of children in African and South Asian countries are regarded as a direct consequence of this disease. In 1952, the United States saw 57,628 cases nationwide, making it the largest polio outbreak in the country.
Regarding the medicine, Polio can not be cured. But there is vaccination, which has become the most important vaccine given to children to avoid polio.
Ebola

Ebola is best known for the big epidemic that was present in 2014 in West Africa. Named after the Ebola river in Africa dates back to 1976. Ebola is a virus from Filoviridae that causes the epidemic of human disease. It is characterized by an extreme fever, a lot of bleeding, and is often fatal. To this day, despite extensive research, there is still no cure for this deadly disease. The mortality rate for ebola-infected humans is 90%
Schizophrenia

Schizophrenia is the most complicated mental disorder. It is a mental illness that paralyzes the patient logically difficult to distinguish reality and fantasy. Doctors are confused because the disease does not specify a medical test. Common symptoms of this disorder include loss of rational thinking skills, delusions, hallucinations, lack of coherence of thought and speech, as well as loss of ability to recognize people in the real world.
Because it can not be properly diagnosed and medically, the disease can not be cured. Although often treated with treatment, but only treat some symptoms only.
Diabetes

Diabetes seems to be everywhere. It's commonplace to barely panic when they're diagnosed with the disease. However, the disease is still dangerous. Sure, it does not turn off directly. But it can cause blindness, heart attack, or you can even lose limbs.
Diabetes is a chronic disorder of carbohydrate metabolism that affects the role of the hormone insulin in the body and is characterized by high levels of sugar in the body. Usually occurs in two forms: Type I and Type II. Type I, or insulin-dependent diabetes, affects the ability of the pancreas to produce insulin and requires patients to take daily hormone injections. Type II or non-insulin-dependent diabetes, is a more common form. It generally develops in people who are overweight and, in some cases, reversible.
Asthma

Asthma sounds normal, but it's actually more dangerous than people realize. It is a chronic lung disease in which the respiratory tract inflamed becomes swollen and very sensitive. It causes wheezing, chest tightness, coughing and tightness. Airways become hypersensitive to various stimuli such as pollen, air pollution, smoke, weather conditions and sometimes exercise.
As the patient breathes, the muscles around the rhythmic airways develop and contract. While contracting, the airways become narrower, keeping the air from flowing into the lungs. Although usually treated with an inhaler, but still there is no cure for it that can heal permanently.
Alzheimer's

Ruining the hearts of suffering people and those around them, Alzheimer's disease remains a major mystery to doctors and scientists. This is actually a type of dementia that causes problems with memory, thought and behavior.
Alzheimer's is a progressive disease, which means the symptoms of dementia gradually worsen over time. In the early stages, there are some mild memory losses. But with late-stage Alzheimer's, patients lose the ability to talk and respond to their environment.
They rarely have a clear moment. Although symptoms can be treated to some extent, they remain unstoppable, and the disease can not be cured or prevented.
Those are some diseases that have not been cured until now. Although there is no cure but we can prevent it early in order not to catch the disease.
