According to Pandemic (and many other sources with similar definitions) a Pandemic is
an epidemic of disease that has spread across a large region, for instance multiple continents or worldwide, affecting a substantial number of people
And according to Dengue fever
Dengue has become a global problem since the Second World War and is common in more than 120 countries, mainly in Asia and South America. (Note: it also exists in North America, Oceania and Africa) About 390 million people are infected a year and approximately 40,000 die.
However, this year we are having dozens of thousands of cases in my country and media only talks about epidemy, also, as far as I know, WHO hasnt declared a Dengue Pandemic.
My question is,
Why Dengue is considered an Epidemic and not a Pandemic?
