Pluribus Virus Explained: Origins, Causes, & Carol’s Immunity

by

In Vince Gilligan’s novel, Pluribus, a strange virus sweeps the globe, infecting everyone except the main character. This unusual circumstance sparks questions about where the virus came from and what lasting effects it will have on people.

The first four minutes of Pluribus depict the initial outbreak and spread of an unusual virus. While the show deliberately keeps many specifics about the virus vague, it provides enough hints to spark viewers’ curiosity and encourage speculation.

The Apple TV sci-fi series centers around Carol, who not only lived through a devastating apocalypse but is the only one brave enough to challenge its impact on people. It remains to be seen how Carol’s journey will progress, but it’s fascinating to consider how the unique apocalypse – one focused on happiness – in Pluribus will reshape the world and Carol herself.

The sci-fi film Pluribus begins with astronomers studying a peculiar microwave signal received from 600 light-years away. At first, they struggle to decipher the message, which turns out to be encoded in Morse code, but they eventually realize it’s a sequence of RNA.

First, the genetic material is converted into DNA and tested on rats using a virus as a delivery method. Later, a scientist finds one of the rats seemingly lifeless, but when she moves it, the rat unexpectedly bites her, effectively making her the first human infected. This bite then sets off a chain reaction, causing the virus to spread.

The virus, found in Pluribus, doesn’t kill people directly. It appears to remove all negative emotions, leaving those infected feeling only happiness and contentment. However, as the virus spreads and society breaks down, millions die during the resulting worldwide collapse.

How The Virus Spread In Pluribus

It all started when a woman, who we now call Patient Zero, kissed a colleague – that’s how the virus jumped to him. From there, it spread like wildfire, person to person, mostly through saliva. Things got really scary when the military discovered what was happening. The infected didn’t just sit back; they actively tried to make the spread worse, using anything and everything they could.

There’s this really unsettling scene where you see a bunch of infected people collecting their own saliva with swabs and saving it. It hit me that they weren’t doing it for testing, but to deliberately contaminate things – water sources, even the kits used to detect the virus! It’s a chilling detail that shows just how far they’d go to spread the infection.

The Apple TV series shows that, similar to the pursuit of happiness, those infected are driven to reproduce. This explains why they desperately seek out and try to ‘cure’ people with immunity.

Carol’s Immunity In Pluribus Explained

Those infected with the virus are all connected by a shared consciousness, effectively functioning as a single entity. They share the same abilities, thoughts, and memories. Because Carol is immune, she remains an individual, retaining her own unique identity.

Okay, so the interesting thing about this character’s ability to resist the infection isn’t about her genes – it’s all about her emotional state. Seriously, she’s presented as incredibly unhappy, and that unhappiness is actually what protects her. We’re so used to heroes battling against darkness, but this film flips that on its head. Instead, our protagonist is fighting a twisted version of happiness, and she’s using her own sadness and negativity as her weapon. It’s a really clever twist on the typical hero’s journey.

How Many Other People Are Immune In Pluribus (Besides Carol)

I was so relieved to learn Carol discovered she wasn’t alone – eleven others had also survived the virus! She managed to connect with a few who spoke English, and I was eager to hear about them. She met Otgonbayar, Xiu Mei, Kusimayu, Laxmi, and Koumba Diabate, and I really hoped they’d share her desire to fight back. It was heartbreaking, though, to learn they all seemed… resigned, almost happy with the way things were now. They didn’t seem interested in joining her resistance at all.

At first, the group tries to understand Carol’s perspective, but they’re ultimately pushed away by her intense anger and the dangerous ways she deals with the infected. The end of Pluribus episode 2 hints that Koumba will still be important to Carol’s story, and it looks like Carol will likely meet more survivors down the road.

How Carol’s Emotions Affect Those With The Virus

Despite appearing unaffected, the first two episodes of Pluribus hint that Carol is somehow linked to the hive mind. Whenever Carol experiences strong emotions directed at the infected, the hive mind malfunctions, causing many of them to have seizures. The show implies that these emotional outbursts from Carol can even be fatal to the infected.

In future storylines for Pluribus, Carol might be able to control those infected by the happiness virus, forcing them to help her discover a cure. Alternatively, if she herself becomes infected, she could leverage her link to the collective consciousness to fight back.
