Specialty	Infectious disease

Generalized lymphadenopathy is swollen lymph glands in many areas of the body.^[1]

Usually this is in response to a body-wide infectious disease such as influenza and will go away once the person has recovered, but sometimes it can persist long-term, even when there is no obvious cause of disease. This is then called persistent generalized lymphadenopathy (PGL).
