A chronic condition is a human health condition or disease that is persistent or otherwise long-lasting in its effects or a disease that comes with 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.
The non-communicable diseases are also usually lasting medical conditions but are separated by their non-infectious causes. In contrast, some chronic diseases, such as HIV/AIDS, are caused by transmissible infections.
Chronic conditions have often been used to describe the various health related states of the human body such as syndromes, physical impairments, disabilities as well as diseases.
Some socioeconomic factors may be considered as a chronic condition as they lead to disability in daily life. An important one that public health officials in the social science setting have begun highlighting is chronic poverty and racism.
In 2015 the World Health Organisation 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) and
