- an aftereffect of a disease, condition, or injury
- a secondary result
A condition which is the consequence of a previous disease or injury.
sequela (UK: /sɪˈkwiːlə/, US: /sɪˈkwɛlə/; usually used in the plural, sequelae) is a pathological condition resulting from a disease, injury, therapy, or other trauma. Typically, a sequela is a chronic condition that is a complication which follows a more acute condition. It is different from, but is a consequence of, the first condition. Timewise, a sequela contrasts with a late effect, where there is a period, sometimes as long as several decades, between the resolution of the initial condition and the appearance of the late effect.In general, non-medical usage, the terms sequela and sequelae mean consequence and consequences.
