The glob al Ebola roll-out?

Ebola breaks new barrier
A Spanish nurse who treated a priest for Ebola he contracted in Sierra Leone is now sick too - making it the first reported case of transmission outside Africa.

Hmmm... if this thing mutates to develop an ability to infect via airborne particles/droplets then things could get *very* bad very quickly.

But never mind, we've got a war against terror to fight -- who cares if millions die of Ebola in the streets. Let's invest in guns and rockets, not healthcare and biocontainment facilities :-(

Virologists are saying it is highly unlikely to become truly airborne. Apparently droplet transmission is possible, but they don't stay in the air very long. I think I heard a radius of 3-4m if an infected person sneezes near you. The half life for it outside of a host is also apparently very low (couple of hours) compared to some other viruses. I think Norovirus is 18 hours half life outside of a host and a much larger radius of droplet transmission. Apparently Norovirus makes a good starting point for modelling transmission because they have similar transmission mechanisms involving infected bodily fluids.

The change in the virus which apparently the researchers are afraid of is a drop in the fatality rate. If that happens then the virus has a good chance of gaining a permanent foot hold in the human population without burning itself out quickly like it had in the past.

The purpose of any virus is to reproduce not kill it's host. Generally when the host dies the virus dies with them.

I recall back in the 1970's AID's was going to be the end of humanity, guess what? We're still here! HIV is a hard virus to catch and is transmitted by body fluids so is Ebola. I doubt that it will ever be spread by aerosols but it's a possibility.
