I agree that worrying will not change anything, but damage limitation can,
handwashing, being cautious over crowded areas, listening to advice from people far more qualified than we are and, acting on the advice.
My 90 year old father lives with us and trying to educate him on handwashing correctly is proving time consuming, he has a daily paper, I'm asking him to wash hands after reading that....met with wide eyed disbelief, but it's a start.
I agree it may seem far less damaging than seasonal flu could be , but the crucial point here is we have a vaccine for that, and certain degree of immunitity as well, Coronavirus is an unknown virus that will infect far more people possibly, therefore the potential to kill more...my opinion only!
