It is indeed a bit concerning, especially because there is no vaccine or cure for it. No, not because it's "incurable". But because there is no financial lobbying going on for the panic to spread like was the case with the bird flu.
I remmeber how people flocked to buy tamiflu. in the end no-one died except some old people who were probably going to die anyway. Therefore the reports of people dying in Africa are more likely to be true and thus you can be a bit more worried.
