The Genesis Plague - Michael Byrnes [132]
Much of the epidemiological detail was lost on Crawford. But he remembered Roselli referring to the rats as a natural ‘intermediate host’ for plague transmission. Stokes preferred to call them a ‘delivery system’. All Crawford knew was that once the brood had reached critical mass, they’d be released from the cave into the Zagros Mountains.
Once unleashed on their new habitat, the rat population would spread out in all directions. And all the while, they’d rampantly breed; just like they’d been doing in this cave - just like their cousins, the Asian black rats or ‘ship rats’, had done before spreading out from China centuries earlier to transmit the Black Death throughout Europe.
Highly intelligent survivalists by nature, the rats would evade capture by burrowing underground, hiding in the mountains’ nooks and crannies, and building hidden nests inside the walls of homes and buildings. Even if they were to be spotted out in the open, the rats were virtually impossible to catch, because for their body size they were among nature’s best athletes: able to sprint at nearly forty kilometers per hour, swim half a kilometre, climb vertically up walls and jump up to over a metre, even squeeze their rubbery bodies through a hole smaller than a quarter. Trapping them was no easy task either since their chisel-like teeth, with more crushing force than a crocodile, could gnaw through metal and wood. At the genetic level, rats were 90 per cent identical to humans - the reason they were favoured for clinical laboratory testing. But a rat’s most important physiological similarity was its brain - nearly identical to a human’s in its ability for spatial memorization.
These rats will be impossible to contain or destroy.
Throughout history, rats had been the carriers and transmitters of over seventy diseases lethal to humans, including typhus, salmonella, parasitic trichinosis and, of course, Yersinia pestis, commonly known as bubonic plague. Similarly, according to Roselli, there’d be numerous ways the rats would transmit the Genesis Plague virions to humans. Crawford could only recall the top three: contamination of food and water supplies via blood, urine, faeces, or saliva; primary contact through a bite (less likely); or most potently, through blood-sucking sand flies and mosquitoes (prolific throughout the Middle East), that would feast on the rats, then relay the virus to humans and livestock through bites. The perfect transmission vector.
Rats provided everything Stokes had wished for: efficiency, cost-effectiveness and anonymity.
At first, Crawford thought Stokes’s plan to settle the score in the Middle East sounded insane. Now that the mission was nearing completion, however, he felt nothing but reverence for the man. Stokes was a visionary; a crusader; a saviour. Stokes would rewrite human history.
And Crawford was determined to play his part - to make history right alongside Stokes. During the past critical hour, however, Crawford had been unable to establish further communication with Stokes. Ye t like every operational detail of Operation Genesis, there was a failsafe for this dilemma - a manual workaround. At this juncture, the mission’s success hinged upon getting the rats out from the cave. Crawford had hoped that despite their neophobic tendencies, the rats would have already made their way outside. But the two blasts that had decimated the cave’s entry tunnels had likely forced the rats to seek an alternative exit; the very survival mechanism that would account for their staying power in the outside world.
At this juncture, all Crawford needed to do was act the role of the Pied Piper and herd the critters out the front door. Though he wasn’t counting on that being the easiest of tasks. With the rats having been down here breeding for over a year, he could hardly imagine just how many there might be inside. And since he recalled that rats evolved three times faster than humans, he wondered what effect the hormone infusions might have had on their behaviour
