I thought at first that she had been bitten (she's getting rabies shots apparently). But then that scenario wouldn't work, right? That would mean that the only way you could get this next "virus" would be through direct contact - like being bitten. What they are saying here is that the virus would be airborne, which is the only way it could become transmissible from human to human.

The whole story sound bizarre. How did she develop symptoms so quickly?
