Without an adequate response, an epidemic can develop into a pandemic, which generally means it has spread to more than one continent.
The novel 'World War Z' is told from the perspectives of so many people - speaking to the narrator - that there's no way a movie could capture all of them. Still, the idea of turning a zombie pandemic into a war story is fascinating and could have translated easily to film.
A pandemic influenza would mean widespread infection essentially throughout every region of the world.
It's the advantage of the virus to spread, and you can only spread when you infect people and they infect other people without necessarily killing them. So if you had 100 percent mortality, the potential pandemic would almost self-eliminate itself.
Security incidents have gone up 5-10 times during the pandemic, so there is an increased need for security operations risk management, identity and access management, data privacy and compliance.
