Foot-and-mouth disease

Foot-and-mouth disease is spreading in south korea these days.
Why is it possible to spread rapidly?

First of all, Preventive measures against epidemics is insufficient.
When it happened, we should have prevented it on a nationwide scale immediately.
In additon, Some cities only prevent their areas from foot-and-mouth disease.

Secondly, All people should actively participate in prevention of epidemics.
Because it can be expanded in the air, It needs all people's participation to be terminated.
For example, Some selfish people don't accept a disinfection because of inconvenience.
