In the United States at least. So if it does happen, thanks to the Left 4 Dead series and a popular culture that often portrays such instances with alarming regularity, the common citizens expects guns for all, right? Nope. Zombie outbreaks, even on a nationwide scale, are like any other disaster. So have to supplies ready and—wait for the Center for Disease Control (CDC)?
Yes, true that. The scientific community believes zombie-ism is the cause of a nasty and infectious virus. To contain it, rather than bring out the napalm and Ar-15s, calls for testing. So:
If zombies did start roaming the streets, CDC would conduct an investigation much like any other disease outbreak. CDC would provide technical assistance to cities, states, or international partners dealing with a zombie infestation. This assistance might include consultation, lab testing and analysis, patient management and care, tracking of contacts, and infection control (including isolation and quarantine). It’s likely that an investigation of this scenario would seek to accomplish several goals: determine the cause of the illness, the source of the infection/virus/toxin, learn how it is transmitted and how readily it is spread, how to break the cycle of transmission and thus prevent further cases, and how patients can best be treated.
It’s a little tongue in cheek. But take it from the CDC; they’re the ones who released this particular bit of news via their official blog.
