Diseases have diverse causes, which can be classified into two broad groups: infectious and noninfectious.

Noninfectious diseases are not communicated from person to person and do not have, or are not known to involve, infectious agents. Some diseases, such as the common cold, are acute, coming on suddenly and lasting for no more than a few weeks. Other diseases, such as arthritis (关节炎), are chronic (长期的), persisting for months or years, or recurring (复发) frequently.
Every disease has certain characteristic effects on the body. Some of these effects, called symptoms and signs, include fever, inflammation, pain, fatigue, dizziness, nausea, and rashes, and are readily apparent to the patient. These symptoms offer important clues that help physicians and other health care professionals make a diagnosis. Many times, however, the symptoms point to sever
A. be saved
