If you look at the long sweep of history, global integration has tended to bring mass pandemics in its wake. My understanding is that you basically got waves of major plagues in the ancient world, pretty much whenever somebody controlled the steppes of Central Asia well enough that substantial commerce between China and the West could take place. Pretty soon afterwards, lots of people died. In the opening of the New World, it wasn't the conquistadors, it was the microbes that really did it here.
Now we have this very integrated world with very uneven levels of public health. You have to think that a pandemic is at least a possibility.
Ebola Relapses Could Be Contagious
Pauline Cafferkey, 39, was admitted to the Queen Elizabeth University Hospital in Glasgow last Tuesday after feeling unwell.
Today NHS Greater Glasgow and Clyde confirmed all close contacts of the nurse since she became symptomatic again have now been identified and 40 of the 58 people offered vaccinations as a precaution.
We were first told that the relapse will not be contagious, and yet they are offering to vaccinate first degree contacts. We have also been told vaccination is effective, but I could see that not being entirely correct.
