For the first part of my look at Batman: Contagion, I want to take a close look at the cause of all the trouble: the Apocalypse Virus.
A viral plague has come to Gotham City: the Apocalypse Virus — unleashed upon the city by the Order of St Dumas. Azrael, once a member of the Order, warns Batman of the impending pandemic.
Azrael describes the Apocalypse virus as a Filovirus.
Batman goes on to state:
A rod-like swift acting family of viruses. Original habitat, the Central American rainforest. They spread as mankind encroached on virgin territory.
Several mutate so fast it’s almost impossible to find a cure. They’re almost always fatal. Ebola Honduras, which dissolves its victims’ flesh from within. Ebola Gulf-A – the so-called Apocalypse Virus.
Filoviruses are a family of pathogenic viruses which cause a particularly nasty type of infection known as a viral hemorrhagic fever. Not all Filoviruses are infectious to humans, but those that are have extremely high fatality rates. At the time the story was written, there is no known cure for any Filovirus.
Ebolavirus is one of two genera in the Filovirus family, and there are five known species of Ebola (and none of them are Ebola Gulf-A, it’s a fictitious virus). Despite what Batman says, the Filoviruses are all from Africa, and none have been found in Central America. There is no Ebola Honduras, so your flesh is safe.
To be overly pedantic, filoviruses are long and threadlike, not rod-like. The prefix filo- means thread and can also be found in words such as filament and (for those of you fond of infectious worms)
filariasis.
A short time later, Batman breaks into an Army germ warfare center and learns:
Ebola Gulf-A – incubation period, 48 hours. Flu-like symptoms when the virus spreads in airborne mucus. Blood leaks from the eyes.
Gulf-A desiccates the muscles, shrinking and deforming them – turning the victim into a gnarled misshapen cripple. Eventually the bones themselves splinter and break – under the incredible pressure. Hence its nickname: the Clench.
Initial flu-like symptoms are commonly seen in Ebola infections. Airborne spread is likely, but not conclusively proven. Blood has been shown to transmit the infection.
A key part of viral hemorrhagic fevers like Ebola is the bleeding (hence the “hemorrhage” in the name). Under normal conditions, the liver makes the proteins that prevent our blood from hemorrhaging. The Ebola infection attacks the liver, stopping the production of these proteins, which ultimately leads to heavy bleeding from pretty much every orifice in the body, including the eyes.
While I appreciate the visual of the misshapen victims of the Clench, the reasoning makes little sense. If the muscles are shrunken and desiccated (dried out), then how would they have the strength to break bones?
I give the writers credit for creating a truly alarming disease. Ebola is frightening enough in the real world, let alone the enhanced version seen here. Both the “Clench” and the “Apocalypse Virus” are nicely evocative names, even if the latter sounds like something that should be found in an X-book. Their underlying science is a little shaky and their geography suspect, but that does little to undermine what they’ve accomplished in creating the “Clench.”
As a final note, there have been some very promising work on both Ebola vaccines and anti-Ebola drugs recently, but none of these were around when the story was written, so it would be unfair to hold that against the writers.
