Well this is just great. They are headed my way, and at first in looking at the map I was relieved that they were going to San Diego - by the position of the star. Then I realized the tag says Mt. Wilson, which is in my old hiking playground.
I searched for CDC lab at Mt. Wilson, and it looks like the writers took advantage of search term proximity or something, as this CDC link includes a discussion about a tick born pathogen discovered in a man working at Mt. Wilson. Maybe they are planning to have these spirochetes be the cause of zombyism, ala syphilis? Except the show says its a virus.
BTW, I've personally never even seen a tick in those particular mountains, unlike say oodles in the Sierras.
These clustered spirochetes look disturbingly like the FSM:
I guess even the FSM, like God, gives with one noodley appendage and takes with the other.
In any case, I think they may also be trying to tell us part of what is coming.
