cause (redirected from causers)

cause

in diseases, an agent, event, condition or characteristic which plays an essential role in producing an occurrence of the disease. Because there is nowadays much less certainty about what actually establishes a disease state it is becoming more common to use terms such as disease determinants, causal association, causal relationship. koch's postulates are no longer the sole criterion used in establishing causality.
