A chronic condition is a human health condition or disease that is persistent or otherwise long-lasting in its effects or a disease that advances over time.
The term chronic is often applied when the course of the disease lasts for more than three month
A chronic course is further distinguished from a recurrent course; recurrent diseases relapse repeatedly, with periods of remission in between.
A chronic condition may be noncommunicable (such as COPD) or a transmissible disease (such as HIV/AIDS).
Chronic conditions have often been used to describe the various health-related states of the human body, such as syndromes, physical impairments, and disabilities as well as diseases.
Some socioeconomic factors may be considered as a chronic condition as they lead to disability in daily life. Public health officials in the social science setting have begun describing two conditions as chronic: chronic poverty and chronic racism.
In 2015 the World Health Organization produced a report on Non-Communicable Diseases, citing the four major types as:
- cardiovascular diseases (including cerebrovascular disease, heart failure, ischemic cardiopathy)
- chronic respiratory diseases (such as chronic obstructive pulmonary disease [COPD]) and asthma)
- diabetes mellitus
