What is the t virus

Management is focused on early detection and preventing the spread of HTLV-1 to others. Screening blood doners, promoting safe sex and discouraging needle sharing can decrease the number of new infections. Mother-to-child transmission can be reduced by screening pregnant women so infected mothers can avoid breastfeeding. Prognosis Prognosis. Ninety-five percent of people with human T- cell leukemia virus , type 1 HTLV-1 never have any signs of symptoms of the infection and do not go on to develop medical problems.

Depending on the subtype of ATL, people usually live an average of 6 months to 2 years following diagnosis. Although chemotherapy can produce a complete remission , it does not alter the life expectancy. Research Research. Clinical Research Resources ClinicalTrials.

PubMed is a searchable database of medical literature and lists journal articles that discuss Human T-cell leukemia virus type 1. Rebecca in particular killed the reborn Marcus and his army, thereby shutting off a massive source of infection.

All of them ended up holed up in the massive Spencer Estate and its adjacent areas, where later the S. Alpha Team entered as well, after suffering a similar fate at the hands of a pack of Cerberus'. Later on, the remaining members of S. This Tyrant killed, albeit temporarily, Albert Wesker, and was destroyed by a rocket blast in the second brawl it offered the remaining S.

After the demolition of the manor, the virus sources were thought stopped definitively, but when William Birkin's subterranean laboratories were attacked by Umbrella's Black Ops in September in an effort to retrieve his G-virus, another outbreak ensued.

This infection encompassed all of Raccoon and ended in the forced termination of the entire city. Umbrella was immediately exposed as creator of the virus due to the enormous amount of evidence produced from the scarce survivors, and was shut down. This ended in the partial demolition of the Umbrella installations there and the total destruction of the South Pole Umbrella Research Center.

Hundreds of people from across the globe were kidnapped and taken there to be made into Tyrants. This infection was caused by the - now mad with power - Commander Vincent Goldman. The island was "sterilized. A final outbreak occurred on an Umbrella-owned luxury cruiser, the Spencer Rain caused by an ex-Umbrella terrorist. All crew and passengers were transformed into T-G Zombies with the new cross virus, the tG virus which was formed with the merge of "t" and "G". The ship was destroyed.

No matter how many outbreaks have been produced by it, the t-virus remains a constant threat to global safety. The t-virus is built like many viruses, but not all. As the cell makes contact with a cell's membrane, it inserts its genetic coding into the cell.

The cell absorbs the viral genome into its own genetic make-up, which takes over the cell's functions. The cell begins to produce offspring of the original virus. The new viruses are then released from the host cell and infect the neighbouring cells, which starts the process all over again. The t-virus kills and replaces the dead mitochondrial organelles with a replica of itself. The virus then combines with other cells to produce energy. The energy produced is just enough to power the motor neurons and the basic lower brain functions.

Not only that, but this bypasses the entire circulatory system, which makes the heart and lungs redundant systems that can be disposed of. The reanimated host body is then left with the intense need to feed in order to replenish energy supplies without having to sacrifice its own tissue.

Actions taken by the host in this time period greatly resemble that of "zombies" depicted in horror movies, and are thus dubbed by that name. However, the t-virus can only properly function by consuming the cell in order to produce its energy and to divide via mitosis to spread around the body.

This slow breakdown of cells leads to the gradual breakdown of the host, causing necrosis. The virus incorporates itself into the host's DNA, which substantially alters it. This is why creatures, such as bees and spiders, only have very minor mutation, such as increased size, when compared to the human mutation caused by the virus. Should the human host be alive at the time of t-virus infection, all higher brain functions are destroyed.

This leaves only the telencephalon, better known as the cerebrum, to govern behaviour. This leaves the infected host with a very animalistic behaviour. Oswell E. Spencer and his colleagues Dr. Edward Ashford and Dr. James Marcus was the birthing of a new age of eugenics with mutagenic viruses improving the human race. To fund this program, dubbed the Wesker Project, it was agreed that strains of the virus should be engineered as a military product, leading to the creation of Umbrella Pharmaceuticals as a front for this research.

Research on Progenitor strains was conducted simultaneously in different laboratories, with Ashford, Marcus and Spencer all engaging in independent research. Spencer's team developed their t-Virus prototype at the Arklay Laboratory, where they had already undergone testing of their "Type A" and "Type B" Progenitor strains. Little is known of Spencer's project, though it would appear Spencer was disappointed in its progress and ordered research data be stolen from his counterparts.

Work on this virus was completely abandoned by Ashford performed research on his t-Virus prototype at his family's stately home in Europe. In , Spencer orchestrated an outbreak at the lab, resulting in Ashford dying from infection. Work on t-Virus was put on hold until the s, when Ashford's cousin Alexia Ashford took charge of the project. The fruit of her labours would ultimately be t-Veronica Virus , created through splicing Veronica Virus into the Progenitor genome.

Alexia would go into hiding in , leading to the misconception that her project was a failure and she had died just as Edward had.

James Marcus' research reached a breakthrough on 13 January , which warranted the official coining of the name "t-Virus" to divorce the strain from Progenitor Virus.

Using the virus on humans saw a very different response compared with Progenitor infection, rather than dying the infected instead became aggressive, were found to have cannibalistic impulses, lost intelligence and suffered from significant necrosis. In , samples and research data were stolen by Dr. William Birkin. Immediately upon his transfer in the Summer of , Birkin began drawing up plans to modify the virus further, splicing RNA from Ebola into the t-Virus' genome.

This, he believed, would make the virus highly contagious while keeping most victims alive as Zombies. Starting around , development of the t-Virus entered Phase 3 with the intention of creating reliable, intelligent B. Its counterpart Tyrant Project had at the time determined it was statistically improbable for any one individual to possess by chance the genetic characteristics to be compatible with the t-Virus strains presently available.

One strategy does not suit all. A strong robust immune system is all, so to repetitively keep over exposing it with antigens via natural or artificial means weakens the immune system in some cases, when the long-term effects are not known yet?
