write a brief overview of the history of pandemic influenza

Pandemic Disease and Public Response Your initial response should be at least 250 words. For this weeks discussion first write a brief overview of the history of pandemic influenza in the world including the ways in which governments responded to the health crisis throughout history. Then how has the human understanding of the cause of the disease changed and how have these changes affected government response and public policy? What have been the consequences of calling a pandemic flu a national security threat? Considering the information you acquired in the reading this week do you think that governments should enforce the flu vaccine each year?
