Endemic (epidemiology)
\ɛnˈdɛmɪk\ \(ɛpəˌdɛmiˈɑləʤi)\
A disease or condition that occurs regularly and consistently within a specific population or geographic area. It is considered stable in terms of its presence and spread over time.
For example, malaria is endemic in many tropical regions, meaning it is consistently present and affects people in those areas year after year.
