Incurable diseases that can infect your body



Everyone knows someone affected with HIV/AIDS, asthma and cancer. As you read this – you might be suffering from a bout of common cold. However, many misconceptions, and wrong beliefs are common among many of these diseases. The most ranked incurable diseases are:

HIV/AIDS
Africa has been the epicentre of HIV/AIDS – and more than 20 million people have died since 1981. HIV slowly attacks and destroys the immune system, the body’s defense against infection, leaving an individual vulnerable to an array of infections that eventually cause death. AIDS is the final stage of HIV infection, during which fatal infections and cancers frequently arise.

Asthma
Defined as a chronic lung disorder in which inflamed airways are prone to narrow, causing period of breathlessness, wheezing, coughing – and chest tightness which ranges from mild to fatal. Inflamed airways become hypersensitive to stimuli, including dust mites, pollen, air pollution, cigarette smoke, medications, weather conditions, exercise – and even stress. Asthmatic episodes may begin suddenly or may take days to develop. About half of all cases occur in persons younger than 10 years of age. Boys are more prone. Asthma during childhood is often related with an inherited susceptibility to allergens such as pollen and dust mites that may induce an allergic reaction.

Diabetes
Diabetes is a disorder of carbohydrate metabolism distinguished by impaired ability of the body to produce insulin and thereby maintain proper levels of sugar in the blood. Type I diabetes – usually arises in childhood. It is a disorder in which the diabetic person’s immune system produces antibodies that destroy the insulin-producing beta cells. Without insulin, daily injections of the hormone are required. Type II diabetes, arises after 40 years of age and increases with age. Arising from either slow pancreatic secretion of insulin or reduced reaction in target cells of the body to secreted insulin – it has a connection to genetics and upper body obesity. Type II diabetes can control blood glucose levels through diet and exercise and – if required, taking insulin injections or medications.

Cancer
Cancer is a grouping of more than 100 distinct diseases illustrating the unrestrained growth of abnormal cells in the body. In developed countries, cancer affects one in every three persons and is a major cause of sickness and death all over the world. Advancement in accurate diagnosis, selective surgery, radiation therapy and chemotherapeutic drugs have brought about a decrease in cancer deaths – at least in developed countries owing to prevention, diagnosis, and treatment of this disease.

Common cold 
You are probably suffering from it now. The common cold is an acute viral infection starting in the upper respiratory tract – spreading to the lower structures, and may cause secondary infections in the eyes or middle ears. In excess of 100 agents cause the common cold, including parainfluenza, influenza, respiratory syncytial viruses, and reoviruses – the most frequent cause. The cold is transmitted from exposure to infected people, not from a cold environment and chilled wet feet. People can carry the virus and communicate it without experiencing any of the symptoms themselves. Incubation is short and usually spans one to four days.
