I will still stick with my local official channels. I will consider a zombie 'virus' outbreak similar to other large scale outbreak of, say, Avian Flu (eg H5N1) or SARS.

I think, one has to be very careful and not to blindly use what we have seen over the years in movies or TV shows. A real life 'zombie virus' might bare some similarities with what we see in movies but there are a lot of differences.

 

I'd skip the shortwave until after the collapse of society. Initially it'll be full of nuts saying all sorts of nutty things. At least after the fall of society you'll know the nuts broadcasting are nuts who've survived like you have. Local channels and internet first.
