vaccination and seasonal predictibility, and known means of transmission, known time of incubation, post infection recovery ... alot of unknown variables. With young (working) people vaccinated, atleast not spread other countries, dense populations and workplaces - to elderly and infirm. With seasonal predictibility, resources can be allocated at the right time - stock up on masks, vacccinate carers. Means of transmission, Droplets for the flu, but now questions if animals are carrierrs and how long it survives on hard surfaces... think trade and saboutage. Time of incubation, this has been very confusing even now. People out of quaranteen represent with symptoms a week or so later. As well post survival residual damage to body systems ? lungs.
i have some Zoono shares and a RN in major hospital. I'm sure many more qualified here than me however.
