Answer:

The correct answer is 2012 = 12/100,000; 2013 = 8/100,000; 2014 = 31/100,000

Explanation:

In this report, the occurrence of Hepatitis A in 2014 was more than twice than the occurrence in 2012.  At community levels, the spread of the disease can be endemic, epidemic or in pandemic proportions.

The spread of the disease in a community or region at a level which is higher than the expectation will be epidemic.  However, mostly people tend to connect large number os incidences with epidemic, even when one case cam be termed as epidemic if the disease is considered to be eliminated perilously.
