As a health reporter in Colorado, I'm not remotely worried about Ebola. While it's possible that a Denver resident could return after becoming infected in the outbreak in Congo, the virus doesn't spread through the air, and people's bodily fluids only become infectious after they start showing symptoms.

But as a human being who doesn't want anybody to die before they've had a long, healthy life, I'm very worried. The virus got a head start when tests for the wrong strain produced false negatives, allowing it to spread to health care workers and others because they didn't know what precautions to take. The existing Ebola vaccines haven't been shown to work against this strain, so officials in the Democratic Republic of the Congo are working without an important tool in an area where armed groups periodically fight each other and the government. Already, more than 100 people have died in Congo, with one death in neighboring Uganda.
