Originally posted by photoptimist What scares the poop out of epidemiologists is that coronaviruses have higher fatality rates (up to 10%), no vaccines, and no guarantees that a mutation might make the virus much more deadly.
No kidding, another big problem with the vaccine that is being developed is will it protect broadly enough? Influenza isn't just one virus, its a whole family of mutant strains. RNA transcription is an inherently error prone replication process* - which is why viruses replicate in such numbers to help evade selective pressures and improve the chances of survival.
Originally posted by photoptimist As scary as a new disease could be (and there are some truly horrendous little cooties floating around out there), the tools available to most modern societies are fairly good at mobilizing resources for containment, treatment, and prevention.
The period of time over which the infection is contagious is of great concern as well, there comes a point where better transport will also encourage wider spread of deadly infections. Killing the host is counterproductive to the ultimate survival of a disease, if it can't spread fast enough. Treating those already infected, Identifying those who are contagious and keeping them contained will be a huge burden especially if the number of cases continues to rise. We are already begining to see industries being shuttered - that has got to hurt economically.
* The common cold, SARS, West Nile Fever, Ebola, Rabies,Hepatitis E/C are all RNA viruses.
