Some people seem confused about the concept of mandatory quarantine simply because, as a society, we have almost completely forgotten about epidemics of deadly infectious diseases.
I have news for you: they are not gone. Various trends are causing this: in the case of Ebola, the ability of people to fly quickly around the world has made a great difference.
There is neither vaccine nor cure for this disease. This is no joke — this is the real deal. There is absolutely nothing unreasonable about quarantine. It was used routinely in the ‘older days’ and guess what: it worked.
