10 Types Of Social Networks

Here is a very unique article detailing ten different types of social networks. It goes over everything from destroying threat networks to sex networks.

I scrolled down to the part in the reading that talked about immunization of networks, thinking about the swine flu and other plagues. Here's what it said:

"Random immunization fails to prevent epidemics of diseases that spread in populations
upon contact between infected individuals [4, 5]; the same is true for
immunization of computers against viruses [47]. Unless almost the entire system
is immunized, the virus continues to spread through the population or computer
network."

So all this fuss about a swine flu vaccine not being avaliable need not to be because it will inevitably spread and everyone has a risk of catching it. Like the CDC has been saying all you can really do is avoid sick people, wash your hands, not touch your face, etc. Makes you wonder how things like the Black Plague ever stopped considering hygiene back then was horrible and the world population was way smaller so it could spread quicker...maybe I missed that day in history class.

I was taught the opposite, that only a certain percent of the population needs to be vaccinated to prevent to spread of the disease. It is called Herd immunity where depending on the disease and how contagious it is, some certain percent of the population needs to be immunized to stop the disease. And it makes sense because if you think about it that even though you might know a few hundred people, the time that you are contagious you will probably only see around 30 of them and most of them you probably won't get close enough to or long enough contact for the disease to spread. So if you have a large enough percent of the population vaccinated, you could make it quite unlike that one non-immune person would be another non-immune (and thus cause the disease to spread).

For the regular flu, they said about 75% of the population needed to be vaccinated.
