It was only a matter of time
- A man in Dallas has been diagnosed with Ebola.
- He traveled from Liberia to the US to visit family.
- People leaving Liberia are screened for Ebola.
- He first experienced symptoms 4 days after arriving in US.
- This means his airport test would have been negative.
- Ebola is only spread through contact with bodily fluids.
- It can only be passed once the victim is showing symptoms.
