Gerry Injects Himself with Deadly Pathogen in Dramatic World War Z Scene

In an intense scene from the 2013 blockbuster World War Z, former UN investigator Gerry Lane (played by Brad Pitt) injects himself with a deadly pathogen from a refrigerated storage box. This shocking twist leaves viewers wondering – what deadly disease did Gerry give himself and why take such an incredible risk?

Gerry Injects Unidentified Lethal Bacteria

Gerry injects himself with a highly pathogenic bacteria in a clear brown liquid form. The exact disease is not confirmed in the film, but it is deadly to humans based on the character‘s reactions.

This bacteria seems to have been in refrigerated storage in the vault Gerry breaks into. Refrigerating pathogens is standard practice to preserve samples for research while containing safety risks.

Several bacteria fit the criteria of being potentially lethal if untreated:

• Anthrax: Causes severe illness and death in 50% of cases if injected. Could be refrigerated for storage.
• Tuberculosis: Infects one-quarter of global population. An injection could spread through blood.
• Meningitis: Fast-acting bacterial illness with injections particularly dangerous.

While we never learn the exact name of Gerry‘s vial, these examples illustrate the variety of deadly bacteria that may have been present in the research vault.

Masking Scent from Zombies with Deadly Deception

So why resort to intentionally infecting himself? Gerry‘s bold move is intended to mask his human scent from the zombies swarming the vault so he can safely walk out.

The logic is that by making himself seem sick, he would blend in with the infected dead and "disappear" from the zombies‘ detection. They would ignore him as one of their own kind.

This trick relies on two key assumptions about World War Z‘s zombie physiology:

1. Zombies identify healthy prey by scent and other cues indicating an intact immune system.
2. Intentionally sickening oneself temporarily throws off these detection cues and provides "camouflage" from the undead.

It‘s a clever deception, albeit with extremely high stakes!

My Take: Far-Fetched But Thrilling Twist

As an avid gamer and zombie genre fan, I have to admit – Gerry‘s high-risk pathogen gambit makes for an exhilarating movie moment.

When that storage box lid clicks open to reveal rows of ominous vials, you know Gerry‘s willing to do anything for even a sliver of hope. The tension spikes as the needle plunges. Talk about no guts, no glory!

Still, analyzing it logically, I do have doubts. Is masking one‘s natural scent really enough to fool zombies attuned to signs of fresh human prey?

And while desperate times call for desperate measures, intentionally infecting yourself with a potentially lethal disease seems beyond reckless. So close to his family, Gerry is taking a frigidly cold gamble on that frosty vial.

But maybe that‘s the point – to show how even level-headed heroes like Gerry will throw pure reason out in favor of bold instinct when their back‘s to the wall.

While unlikely to be an advisable zombie outbreak survival tactic, Gerry‘s all-in move makes for prime blockbuster entertainment.

By the Numbers: Zombie Virus Lore and Disease Pathology

To provide deeper medical context on Gerry‘s dramatic disease gambit, let‘s crunch some numbers on disease pathology and zombie virus mythology:

• 10-20% – Approximate untreated mortality rate of diseases like meningitis and anthrax potentially stored in the lab vault [1, 2]
• 32% or 107 million – Estimated post-zombie apocalypse population density in the US according to some mathematical models. [3]
• 100% – Fatality rate of infected victims in much zombie fiction, indicating total collapse of immune response [4].

Juxtaposing this data highlights the extremely high stakes of Gerry using disease camouflage versus the certain doom the zombies represent. No wonder he rolled the dice!

…But Would It Really Have Worked?

Here‘s the million dollar question though – could infecting himself with a pathogenic disease actually hide Gerry‘s human scent from the zombies?

Analyzing this hinges on whether the undead hunt by scent at all and if so, what exactly they detect.

| Evidence FOR Disease Camouflage | Evidence AGAINST Disease Camouflage
———— | ————- | ————-
Zombie Scent Tracking | Certain zombie genres emphasize heightened zombie smell for finding prey, like geese locating wounded members of a flock. [5] | More recent science points to loss of many sensory functions for reanimated dead, putting in doubt their scent tracking prowess. [6] Immune Response | Some fictional zombies avoid the terminally sick and dying, preferring victims with stronger disease resistance. [5] | However, close-range pathogens likely don‘t inhibit human scent enough to fool zombies and avoid attack.
Masking Scent Precedent | Hunters sometimes mask human scent using special soaps or clothing to avoid spooking prey. [7] | Masking attempts still rarely fool prey‘s olefaction and most attacks likely proceed as normal.

This analysis shows it‘s possible zombies use scent tracking and key in on prey health. But evidence is shaky on disease truly masking someone from close-range swarm attacks.

My take – Gerry‘s trick might earn a brief distraction, but lasting obscurity from those viral visual receptors still seems tragically slim.

But when you‘ve got zombies flooding the hallway, what‘s an aspiring action hero to do besides load that virus vial and let slip the infected dogs of war?

Here goes nothing Gerry – good luck dude!
