Ebola

Can someone please explain to me why we are still letting people in the country from West Africa?  I read some article today by some all knowing ass bag that said that if we did that, the disease will spread quicker.  What?   Huh?   Seriously, explain this to me.  If we quarantined people that had passports from Ebola hot zones, it will spread quicker!?!?!?   Are there editors that question nothing people put out anymore?  If I had the flu I would not go to the office.  Guess why…..cause I do not want to give anyone else the flu!!!  By this douche's logic I should go to work and lick everyone's space bar and cough in the coffee.   With his thinking the flu is unable to spread in my office now.   What am I missing?
