You're right that it spreads slowly and is hard to get in the beginning and people going about their lives aren't going to get infected from this, but it's easy for a healthcare worker to get infected. It's super contagious especially at the end stages which is why this is so dangerous for healthcare workers. Just one droplet of blood of at the end stages can contain a hundred million particles of the virus. A contagion that you have to deal with in this manner and be 100% perfect around is extremely contagious for a nurse or caregiver. The reproductive rate of ebola here in the US, a virus which there is no cure and has a 70% horrible, ghastly, undignified death rate is at 2 right now. So bravo Dallas. Bravo US. So far we've done no better dealing with this with our supposed superior healthcare system than west africa so far. How arrogant we are.
