Those At Greatest Risk

Those at greatest risk of catching Ebola have close and prolonged contact with Ebola victims. Caregivers seem particularly at risk probably because of their proximity (closeness) and the length of time they are in contact.

One measure of how much we need to fear a particular virus is how effective it is in crossing hosts. Some viruses are really incredible at it, such as measles which infects an average of 18 other people from each sick person.

The chart below puts Ebola at the very low end of infectivity:

There are a host of complicating factors at work in determining just how infective a virus is, and one of those factors is whether or not you can look at the person while they are in the transmissive phase and see that they are sick. If you can, you may avoid them or take extra precautions.

Again, the Ebola victims are in obviously bad shape by the time they are in the infective stage.

However, I think we are going to have to nudge Ebola over to the right a bit on that above chart because it now seems probable that the mode of infection for this current strain is a whole lot easier than initially thought.

The CDC still claims that the only way to catch Ebola is by direct contact with fluids from an infected person.

However, it's been known since 2012 that direct contact is not necessary as this study rather conclusively proved that… [Sign In/Enroll to read the full article]
