Virus infection wikipedia

All samples of the vaccine as well as the research data were destroyed due both to the destruction of Raccoon City itself and attempts by Umbrella to destroy evidence. Dubbed merely the t-Vaccine, it represented the US' commitments to nullifying the threat posed by the t-Virus. Though it had a successful trial in both India and the American city of Harvardville , a terrorist bombing of the laboratory complex destroyed the research data and all but one sample.

Alpha Team. Above the Rim. Caucasus outbreak. Anti-Virus Weapon Protocol No. Typically, for an infection to spread to victims wearing personal protective equipment PPE like the CEDA agent, a breach incurs exposure in one of two ways and also indicates the route of infection. The second involves a breach in the exterior air supply to the victim which indicates an airborne or aerosol strain of the virus is also at work. This was made more plausible in The Sacrifice comic where it is mentioned that the virus is "sometimes airborne, sometimes not.

However, this suggestion is atypical of rabies and is more common in influenza strains. From the evidence presented in the game, biting and fluid exchange i. A separate airborne strain of the virus could explain the speed which the Infection occurred. If a victim is Infected with both bite and airborne strains, it could also explain the fast mutation of the virus in victims and the development of Special Infected. The Sacrifice tells us now that despite the name and tendency to spread through bites, Green Flu is not rabies or flu, but rather a new virus that mutates on a daily basis, being absurdly dynamic and therefore impossible to counter.

The Infected appeared to favor the immediate death of the Survivors rather than Infection through biting or some other method which might mean that they displayed some ability to detect immunity or still had some small sense of self-preservation.

It could also be that the Infected lost their traces of humanity and ran on animal instinct. It is not explained under which factors that the certain victims became Common Infected while others became Special Infected , though it is possible that there are different strains of the virus that can only survive inside certain host bodies.

It could also depend on the mental state, habits of the host pre-Infection or temperament of the Infected. Special Infected are gender-based. However, the prospect of having multiple strains of a particular virus onset so quickly and naturally is not very plausible for today's scientific and medical standards. The evolutionary trends showed that it takes hundreds to thousands of years for recombinant or similar strains of a particular virus to become so populous that they can be considered a completely separate strain.

If there are different strains of the virus at work which caused the onset of special Infection symptoms, it is more likely that the virus was engineered. It should be noted that "engineered" is a vague explanation and could mean anything from a biological weapon to an experimental vaccination gone bad.

It should also be noted that random mutations of a virus and the existence of different strains of a single virus are two separate scenarios. The idea of an engineered virus only applies to that. Immediately after the aforementioned intro card for the opening cutscene, Bill is seen discovering a viscous, bright green substance in or on It's difficult to discern a dead And presumably Infected body.

He mentions that he's never seen anything like it before, but it doesn't seem to hurt him in any immediate way and neither does smearing it on Francis ' vest. This is most likely Boomer bile A Boomer corpse is seen in the background if observed closely enough. The substance was said to reek and Bill claims that the liquid was a sign that the Infected were "changing.

This could mean that the Special Infected were just starting to develop and this was the Survivors' first encounter with one. This is backed up by how Zoey approaches what she assumes is a Survivor crying, despite the obvious signs of her being a Witch , implying that she has never encountered one before. However, it seems that Bill recognized the Witch , ordering Zoey to shut her light off and back away or alternatively, may have realized the Witch as Infected due to her being illuminated by the lighting.

The CEDA posters in the airport suggested that the Infection is related to livestock and toward the end of the Blood Harvest campaign, the player will encounter several deceased cows, neatly stacked atop one another.

The cows typically have the skin around their skull missing, indicating that rabies tests were performed on the animals. The cows in the Barns level of Dark Carnival and in the Swamp Town level of Swamp Fever also have the skin to their heads removed and upon seeing the dead cow pile in the Swamp Town, Rochelle sometimes mentions that the news claimed that the virus spread through livestock and believes that the natives of the town, determined to survive the Infection on their own, killed their own livestock to prevent an outbreak.

All of the dead cows might be a reference to real-world Mad Cow Disease Which caused the massacre of many livestock such as cows in order to eliminate it. However, the Mad Cow Disease is a prion and the Green Flu is a very dangerous virus which explains why it was less rampant than that , among all of the other inspiration from real-world diseases.

There is also writing in a safe room within the No Mercy campaign and seen before the River Tour in The Passing that disregards the CEDA 's safety step that tells the Survivors to treat the Infection as though it was airborne Despite the Military Doctor's claims that it's not always airborne.

Philadelphia is shown as the epicenter The map proves that the epicenter of the Infection was in Pennsylvania where it quickly spread across the eastern United States. This provides the explanation for why Fairfield's cityscape was ravaged in the first game. Most of the cities in the region covered are destroyed by the Infection, showing how fast-spreading it is. The map indicates that despite originating in Pennsylvania, the Infection might not have spread north as there are no "X's" in New York, meaning that the region may not be overrun.

The map also seems to indicate that the Infection hasn't spread to Canada yet. It should be noted that the larger cities such as Toronto, Montreal and Ottawa fell within the first circle indicating the spread of the Infection, suggesting that they too are besieged.

Some of the larger cities in the Infected area have not been crossed out, indicating that the cities may still be viable extraction sites that have been locked down by the military. However, Philadelphia is in the Infection epicenter so it is likely that it was overrun soon after the Infection started and the nation's capital, Washington, D.

The only viable evacuation point left in the South Atlantic region is New Orleans, Louisiana which itself is besieged three weeks after the first Infection. The Infection also reached Florida as the cities of Clearwater and an area north of Fort Lauderdale are both crossed out, indicating that those cities fell.

However, the Infection may be far more spread out than just the X'd out cities since the only cities with X's are ones on the evacuation route These cities had white boxes on them. After the Infection consumed Fairfield , it spread to the southern United States and led to more and more groups of Survivors to arise to try and get to the safe zones created by the government which as it was seen in the Left 4 Dead 2 trailer, started bombing the cities to stop the Infection from spreading.

A CEDA evacuation poster in Crash Course seems to imply that the Infection spread all over the United States as there are safe zones indicated in the Northeast, Midwest, South and West which the West, Midwest and Northeast are crossed out, meaning that they were besieged, possibly hinting that the Infection may be climate-based. The U. In the South, Atlanta and New Orleans were both fortified, but there are reports that Atlanta was either overrun or the military pulled out.

Regardless of what happened, New Orleans is the last known evacuation center by the time that the Survivors get there, but was soon overrun with the military resorting to bombing the area. In Dead Center and Crash Course, every evacuation center is crossed out except the evacuation center in Oregon state, which has an orange line leading to the area, but the section of the map containing the center's icon is torn, and it too appears to be crossed off.

Because the map only covered the South Atlantic area, the status of the other evacuation areas are still unclear, though going on the prior evidence, the other safe zones are either overrun or under heavy Infected attack. Rural areas may have been the first to become overrun by the Infected. Animals were probably the first to contract the disease Other than the first initial, unknown infection which could explain the piles of dead cattle on rural campaigns such as Blood Harvest.

Alternatively, the cows may have been killed due to human paranoia, similar to Egypt killing all of its pig population during the real-life event flu pandemic Also known as swine flu for much the same reasons.

There are also posters at Metro International Airport which asked the people to wear masks and tell all who have been in contact with livestock to tell the airport staff immediately. The international spread of the Green Flu is never mentioned or elaborated on. It may have spread to Canada, Mexico, or even the rest of the continental Americas, but its spread to Europe, Africa, Asia, and Oceania is unknown.

Due to Metro International Airport being overrun, and the Green Flu having already infected almost all of the United States, it is possible that the Green Flu has spread internationally as well, though the extent of the infection and the status of survivors in other countries is unknown.

Little is known of the exact dates and time is rarely given, only being found in scattered pieces of Graffiti in safe rooms and various hints on posters found throughout the game. Based on the Graffiti found in various saferooms, a number of dates are given:.

Through the abduction of locals, the NEST researchers were able to get their hands on a number of test subjects for both projects, including children at a nearby orphanage.

The accelerated use of test subjects was, in fact, so high that the newly commissioned Incineration Disposal Plant PA suffered a biohazard due to having to process too much biowaste. As the months drew on, Dr. Birkin became increasingly frustrated with Umbrella's board of executives, with both becoming increasingly suspicious the other would seize the completed virus for themselves.

He entered secret negotiations with the US military, instead, expecting to earn protection as a new addition to their own bio-weapons project. Birkin for crimes against Umbrella and seize the virus to complete its research under Dr. Henry in France. Birkin in their recovery.

In his dying actions, he infected himself with a remaining sample of Golgotha and mutated into a powerful G mutant that massacred the security team, and leaked both Golgotha and the Tyrant Virus into the sewers. As Raccoon City soon fell to a t-Virus outbreak, Dr. Birkin continued to wander around, seeking people to implant with G-embryos to propagate his new species.

How many Gs were created is uncertain, though it is known some corpses were also infected with the virus and became G-Zombies. Further attempts to steal Golgotha continued during the outbreak.

Monica and a man later known as Dr. Frederic Downing both tried to escape Raccoon City with samples. In Dr. Monica's case she stole an embryo from an pre-final G test, and was killed by it during her escape attempt.

Downing's case, he succeeded in escaping with a virus sample, either from the finalised version or a near-finalised, and tried to make a new life for himself outside Raccoon City. The US Army made an attempt to recover the virus in the form of Delta Force , and used Umbrella's private subway system to get to the lab and retrieve it; unfortunately for them they took the wrong route and were killed at the PA plant.

Umbrella's own attempt to retrieve Golgotha succeeded in the early hours of 30 September, when Alpha Team leader "HUNK" recovered a sample and got in touch with an Umbrella helicopter. In the early hours of 30 September, Dr. Birkin's wife, Dr. This vaccine was designed to halt mutations caused by the virus, [10] but as a vaccine could not reverse mutation, the recommended procedure was an emergency surgery to remove G-cells in the body. This did not take place due to the severity of the outbreak, made worse by the facility undergoing a self-destruct and Annette's death.

At the same time, the facility was infiltrated by Ada Wong, an agent for a rival company sent to retrieve a sample of Golgotha. Wong ultimately failed to retrieve a sample, though escaped with a skin tissue sample taken from Dr. Birkin was himself killed attempting to escape NEST in an underground train, though accounts differ as to if he was killed by the train self-destructing or being consumed by the explosion from NEST.

Further research and modification of the Golgotha Virus took place in the years after Raccoon City, with Umbrella Europe, the rival company, Dr. Downing and the US military all succeeding in retrieving samples, the latter through placing Sherry Birkin in government custody as a means of both studying her G-cells and keeping her away from those seeking the virus.
