ACUTE, CHRONIC , INFECTIOUS DISEASES

Three Types Of Diseases

3.Infectious Disease

1.Acute Disease

2.Chronic Disease

1.Acute Disease

An acute disease is a disease with a rapid onset and/or a short course.Acute may be used to distinguish a disease from a chronic form, such as acute leukemia and chronic leukemia, or to highlight the sudden onset of a disease, such as acute myocardial infarction.The word 'acute' may also be used in the context of medicine to refer to the acute phase of injury, referring to the immediate post-injury healing processes.[citation needed].

Acute care

Acute care is the early and specialist management of adult patients suffering from a wide range of medical conditions requiring urgent or emergency care usually within 48 hours of admission or referral from other specialties.Acute hospitals are those intended for short-term medical and/or surgical treatment and care. The related medical specialty is acute medicine.

2. Chronic Disease

A chronic condition is a human health condition or disease that is persistent or otherwise long-lasting in its effect .The term chronic is usually applied when the course of the disease lasts for more than three months.Common chronic diseases include arthritis, asthma, cancer, COPD, diabetes and AIDS.

In medicine, the opposite of chronic is acute. A chronic course is further distinguished from a recurrent course; recurrent diseases relapse repeatedly, with periods of remission in between. The non-communicable diseases are also usually lasting medical conditions but are separated by their noninfectious causes. In contrast, some chronic diseases, such as HIV/AIDS, are caused by transmissible infections.

Chronic Care and the Medical System

Historically, there has been little coordination across the multiple settings, providers and treatments of chronic illness care. In addition, the treatments for chronic diseases are often complicated, making it difficult for patients to comply with treatment protocols.Effective medical care usually requires longer visits to the doctor's office than is common in acute care. Moreover, in treating chronic illnesses, the same intervention, whether medical or behavioral, may differ in effectiveness depending on when in the course of the illness the intervention is suggested.

Fragmentation of care is a risk for patients with chronic diseases, because frequently multiple chronic diseases coexist. Necessary interventions can require input from multiple specialists that may not usually work together, and to be effective, they require close, careful coordination.As a consequence, patients with chronic conditions can fare poorly in the current acute-care model of care delivery.

3.Infectious Disease

Infectious disease disease caused by an infectious agent such as a bacterium, virus, protozoan, or fungus that can be passed on to others.Infectious diseases are responsible for a quarter to a third of all deaths worldwide. Infectious diseases account for more than half of all deaths in children under the age of 5. Of the top ten causes of death compiled by the World Health Organization, five are due to infectious diseases.

The top single agent killers are HIV/AIDS, malaria and tuberculosis. The other top killers are lower respiratory infections and diarrheal diseases, which are caused by a variety of agents.
