Expert writing Tips
Best practice
In scientific writing, use "occurrence of morbidity" when you need to specifically emphasize the act or instance of a disease or health condition arising, rather than its overall prevalence or impact.
Common error
Avoid using "occurrence of morbidity" when you actually intend to describe how widespread a disease is within a population at a given time. "Prevalence of morbidity" or simply "morbidity rate" are more appropriate for describing distribution, while "occurrence" emphasizes the event of a disease arising.
