Incidence Vs. Prevalence

TESTE DEIN WISSEN


The incidence represents the number of new cases arising in a population over a given time period, and prevalence is the total number of cases (new and existing cases) of the disease in a given population.

The immune response is normally protective, but in some circumstances the reaction may become
excessive (e.g. hypersensitivity reactions to allergens - anaphylactic shock) or may act against the body’s
own cells (e.g. autoimmune disease – thyroiditis, myasthenia gravis), or may be absent or depressed (e.g.
severe combined immunodeficiency disease, immunosuppressive therapy).

anaphylactic shock: Anaphylaxis causes your immune system to release a flood of chemicals that can cause you to go into shock - your blood pressure drops suddenly and your airways narrow, blocking breathing. Signs and symptoms include a rapid, weak pulse; a skin rash; and nausea and vomiting. 

thyroiditis: Thyroiditis is the swelling, or inflammation, of the thyroid gland and can lead to over- or under-production of thyroid hormone. 

myasthenia gravis: Myasthenia gravis (MG) is a chronic autoimmune disorder in which antibodies destroy the communication between nerves and muscle, resulting in weakness of the skeletal muscles. Myasthenia gravis affects the voluntary muscles of the body, especially those that control the eyes, mouth, throat and limbs.

signs - those signs that can be objectively observed or measured by a physician, eg fever, a swollen ankle, an abnormal heartbeat or the alteration of some physiological, biochemical or morphological parameter, and

clinical symptoms - subjective complaints described by the patient, eg pain, dizziness, nausea. In many cases though, these changes appear late in the disease process, long after a disease is present and has been acting at the cellular level.
