a. Epidemic disease
b. Pandemic disease
c. Endemic disease

e. Sporadic disease

Epidemic disease

Explanation:

An epidemic disease is a disease normally infectious, that spreads so fast among a specific population over time.  Epidemic diseases are limited to a specific population and it normally exceeds the extent of the disease occurrence predicted by epidemiologists.

Dengue fever is a viral infection that is caused by female Aedes mosquito, normally found in the tropics. Dengue fever is not a common disease in the USA and the number of cases of dengue fever between March and November 2010 rose to 66 which defiles predictions.

Since the disease rose above the number of expected cases and it is limited to a small population it is termed epidemic disease
