worker who performs functions related to care. but has no professional, paraprofessional or tertiary education” [9]. On the
other hand, a more recent WHO technical brief noted “CHW is often referred to. volunteer or salaried, professionals or lay
health workers.” [8]. With this unclear definition, CHW can be regarded either as lay health workers or as paraprofessionals performing a voluntary, compensated, or paid community services.
