Worst diseases that AIDS
The acquired immunodeficiency syndrome (AIDS) is one of the diseases most lethal in modern culture. In the United States, AIDS is the fifth leading cause of death for people between the ages of 25 to 44, according to the Health Guide New York Times. This disease has no cure, but modern medicine has found numerous medications that prevent AIDS patient cause a quick death. There are other diseases that may have a more rapid progression, are also fatal or incurable. These diseases have a high mortality rate and are generally intractable. Although AIDS was once considered to be the worst diseases, other diseases can now be more dangerous.
Cancer is one of the diseases most deadly today. The cancer starts in the basic building blocks of the human body, cells, says Medline Plus, a website of the National Institutes of Health. The disease causes the cells to reproduce even when new are needed. This excess cells not age and begin to form a mass called a tumor. Tumors become cancerous only when they start to invade nearby tissue and grow elsewhere in the body. These tumors are called malignant cancerous tumors. Cancer can occur in almost any part of the body. Cancer can be found in the brain, skin, kidney, liver, heart or digestive tract. The disease can spread to almost any part of the body through the bloodstream or through the lymphatic system. The type of cancer depends on the initial origin of cancer cells. The colon cancer that spreads to the liver is still called colon cancer. Treatment options for early stages of cancer include surgery, radiation, chemotherapy or a combination of all three. However, in advanced cases of cancer that has spread to many other organs, treatment is rarely curative. Patients with stages advanced cancer have a very poor prognosis and generally live 6 to 12 months after diagnosis.
There is a rare form of disease rapidly progressive, called disease prion, which destroy the brain and central nervous system of a patient, according to the Center for Disease Control and Prevention of Diseases . The diseases are prion disease Creutzfeldt-Jakob disease or mad cow disease, fatal familial insomnia and Kuru. These diseases often have a long incubation period in which no symptoms. Patients can live for over 10 years before developing symptoms. However, once symptoms develop, the disease quickly destroys the brain and other nerves. Patients develop confusion, memory loss, behavioral changes, drowsiness and pain. No treatment for these is unknown diseases . Furthermore, the diseases are always fatal prion.
Ebola hemorrhagic fever
Ebola hemorrhagic fever (EHF) is a viral disease that is one of the diseases most dangerous known to humans, according to the World Health Organization. The virus is transmitted by direct contact with blood or fluid body , and tissues of infected patients. Once infected, patients develop massive bleeding. Patients begin to bleed from the gums, eyes, nose, anus, and nails. The Ebola virus can also cause patients to cough or vomit blood. The first case of Ebola in Africa was in 1976. Disease seems to erupt sporadically in parts of Africa. There is no definitive treatment for the disease. General supportive care such as fluid replacement and reduction of fever, can be given to patients, but usually the patient’s immune system is only to fight the virus. In 25 to 90 percent of cases, the virus overwhelm the immune system and kills the patient.
