All disease suck. Especially since we are on the infected end. 🙁
But nature has it's reasons and the more exotic killers are just out for that... destruction. Exotic killers like Ebola, Marburg, Crimean Congo, Machupo, Lassa, EEE, WEE, Hanta and a few other wolves are out there waiting to pounce. The CDC calls them emerging pathogens. Some reduce the body to bones and liquid, i.e. the three Ebolas and Marburg. AIDS is a slow burner by comparison, but still a dangerous pathogen. In fact, Ebola and Marburg will do to the human body in 5 days what AIDS will take a year to do. But Humans are careless and unclean and that what causes diseases like SARS to spread so rapidly. It is a derivative of the common cold and the flu. Our habits cause the pandemics.
Ebola is a disease (good or bad). There are people who have survived the "slate wiper" strain of Ebola. Ebola Zaire which kills 90% of the people infected by it. From the survivor vaccines can be made. Just like any other disease. The Flu and the common cold are successful because they are rapid mutators which is why making vaccines is nearly impossible. SARS is the same.
The 3 Ebolas can mutate fast like viruses do, but they also kill more rapidly.
sorry about this but it's ironyhttp://www.rotten.com/library/medicine/epidemics/sars/ 😂
