“How is it possible one person could have that many diseases in them?”
“One person, no. But this is a cumulative effect. A bites B. Between blood loss, the shock of the bite, and whatever germs or viruses A just pumped in, B weakens and dies. Now B becomes an ex and bites C, but C gets both A’s and B’s diseases. When C becomes an ex, the next victim gets A, B, and C’s infections. It’s like a reverse-pyramid scheme, where every iteration gets everything the previous ones had.”
Stealth gave a faint nod. “Which is why the outbreak spread faster as it grew.”
“Right. After five or six generations of exes they each had dozens, maybe even hundreds of diseases in them. Think of Los Angeles two years ago. Imagine how many different bacteria and viruses there were in that ninety or so square mile area. The common cold. Chicken pox. Measles. Mumps. A couple strains of influenza. A few dozen different STDs. Even some folks with typhoid, Lyme disease, or malaria. You couldn’t come up with a disease that wasn’t represented in L.A. somewhere. Two months in getting bitten by an ex was like getting injected with the CDC’s wish list. Once you add an immunodeficiency disease like HIV into that mix, well...” She shrugged.
Richard-something and one of the women murmured. Gorgon swore out loud.
“If everyone in the Mount submitted to blood tests,” Connolly continued, “we’d find out the majority of us are infected with the ex-virus. It just doesn’t do anything until you die.”
Stealth tapped her fingers together. “So the early cases of people being cured?”
The doctor shook her head. “They were cured or stabilized as far as whatever other diseases they’d contracted from their bites, but... no. If and when they did die, I’d guess they still became exes. There’s no way to be sure until a bunch of people die under conventional circumstances. Our preliminary tests seem to confirm it, though.” She took a moment, weighing a thought in her mind. “I need to say... this is the final nail as far any hopes for a cure go.”
Christian tilted her head. “How so?”
“As I said, the ex-virus itself isn’t fatal. It didn’t kill anyone. Every ex out there died of influenza, measles, blood loss... something else. They were killed by the secondary effects of the bite. They’re just as dead as anyone else you ever heard of who died from a disease.”
Richard-something raised his hand. “Do you know yet why it brings them back to life?”
Josh cracked the knuckles of his good hand against his thumb. “While a person might be dead, many elements of their body remain alive for hours, even days. You’ve all heard of hair and fingernails growing on a corpse as the skin cells continue to function. Transplants involve taking the still-living organs from a dead individual. Even at the grocery store, the beef or chicken you bought from the meat case was fresh because, on a cellular level, it was still alive.”
Doctor Connolly nodded. “The ex-virus toughens up cells, makes them hardier. So while the person dies, their individual cells don’t break down as fast, and the dead body continues on as a gigantic aggregate of living cells joined by the virus.”
“But how?”
“Still working on that one. There’s a good chance we’ll never know for sure. The ex-virus doesn’t behave like anything else on record and we don’t have the resources to study it more in depth than we are. It seems to involve the central nervous system as people have suspected from the start. That’s why destroying the brain is the only thing that stops them—-the virus is all through the body, but it primarily resides in the brain and sends impulses along the nerves. You’ll still have the enhanced cells, but nothing stimulating them into action.”
Doctor Connolly bent down and tapped her screen to advance her notes. “On top of that,” she continued, “they’re cold. It seems an active process of the infection is to lower a body’s core temperature down into the fifties after death. This helps slow the decay rate even further.”
“So,” Stealth said, “can you estimate how long they last?”
“Off everything we’ve seen so far, I’m going to say the average ex can exist for twenty-eight months before decay progresses to a point where it can no longer remain active. Give or take two months, and not counting outside influences. Farther north, with seasonal changes, one could exist for four or five years. In the tropics, with the constant heat and humidity, a few months less. That cold snap we had back in February probably added a few weeks to all their lives here.” She shrugged.
“It’s hard to make any exact estimates without knowing the particulars of patient zero,” said Josh. “Since we’ll never know exactly when she or he changed, making those initial calculations is impossible.”
