Stop Ebola spread to other countries

They are now flying in sick born US Citizens back to the United States. I feel bad for all the victims. And I pray for all of you. Why is our government trying to bring sick, contagious, people to be cured here. Cure them in Africa. Or don't you want to share all the vaccines with non US citizens. As a US citizen this really worries me. This is scary. Our government tells everyone in the effected areas, to not work, travel by plane, car anything but we are bringing home sick? They say it's not likely to spread to the US. But is already cases in Canada, including a USA doctor, the UK, Japan, and Australia. Even more scarier, they have tested most subjects and they came back negative but still showed symptoms. These people were wearing full biohazard gear when they contracted the virus. And the CDC wants us to believe we are not all at risk?! It takes about 20 days for symptoms to show, once infected. Do you know how many people would possibly come into contact with that infected person before symptoms show up? And it would probably be mistaken for a cold or the flu, thus exponentially increasing, and probably guaranteeing, the American ebola epidemic. This needs to stay in Africa. You want a case study? Go over there. SIgn this and help stop the spread to every where.
