Discussion

A concept closely related to the spectrum of disease is the concept of the iceberg phenomenon of disease. According to this concept, disease in a community may be compared with an iceberg. The floating tip of the iceberg represents what the physician sees in the community. i.e clinical cases. The vast submerged portion of the iceberg represents the hidden mass of disease. ie latent, inapparent, presymtomatic and undiagnosed cases and carriers in the community.

Explanation

The waterline represents the demarcation between the apparent and inapparent disease.

Comments

Please note that at first look, this appears as a dummy question. But the answer is very clear if you refer Park.

Tips

The unknown morbidity (ie the submerged portion of the iceberg) far exceeds the known morbidity in diseases like Hypertension, Diabetes, Anemia, Malnutrition, Mental illness.
