i figured it out

[funkthehouse]

thanks for the ideas but i got a better understanding from my textbook

[victor]

for the spread...just refer to Orthomyxovirus.
for the lethal...just refer to Filovirus.
for the uncurable in long period...just refer to Retroviridae, genus Lentivirinae

Actually I like this kind of designing question...since I really wanna create one...

[funkthehouse]

i am trying to compose an essay not create a virus that already exists, i need to know how i can design a virus that will only affect one individual, does it have something to do with receptor sites? antigens? antibodies? please help this assignment is confusing me, thanks

Serve uncooked food, the oldest method in history.

Hmm..first, you've to find a specific receptor on that person..there you'll have to know about his/her medical records. After that, you can design a virus with that specific antireceptor.
What I can imagine is designing a virus which can cause great anaphylactic syndromes (so, his/her immune system is the one who kill him/her...the virus is only as an initiator)...

[mkwaje]

hmmm.. interesting, but don't you think its difficult to find receptors unique to just a single person? What I'm thinking is that what makes each of us unique? Bottom line is only our DNA are different and not by much. So design you can probably design a human virus that integrates into the chromosome somehow able to "sense" that unique DNA sequence of target human and then the structural genes in your virus will be trigerred given the appropriate DNA sequences. Now there are ways to kill a person with a designed virus, targetting a specific person is more difficult though; with a lot of work, time and funding, it can probably be done; so its probably easier to kill him with a toxin in the food or something

Ok, this is my idea which is probably wrong cuz i'm just a high school student.Anyway, i think in order for it to kill a specific person it would have to work on their DNA. If you could design a virus to work like an antigen then it would enter the body and recognize it's antigens as "foreign" and shuffle the DNA to produce antibodies against them. When this happens the immune system should break down considerably leaving the virus to move through the cell surface membranes of all the cells and continue it's work.
In order for this to work, the virus must be swift so that it can get to the nucleus faster than the self antigens. It must therefore have external structures such as flagella or cilia to help it move along.
It must also contain a mutagen such as formaldehyde which will cause the shuffling of DNA bases so as to produce the antibodies nessecary.
The size of the virus must be very small like that of a water molecule and it's surface must be polar so that it will pass freely and quickly from cell to cell through the surface membranes

As I know even the smallest virus is much bigger than a water molecule.

What about polar surfase - I think, it is possible if to use antistatic electrecity, but how to do this is probably easy question for victor

This sounds like a virus from the game Metal Gear Solid, they called it the FoxDie

[Ultrashogun]

Identification of target cells could work with MHC recognition.

[Mjhavok]

If it was possible to create a virus to kill one specific person and not just a gender or a race, how long would it last like this? Viruses mutate and what if this one did and it mutated to kill not just a specific person.

Also what class is this essay for. Your teacher/lecturer sounds cool giving you an assignment like this.

Unless certain governments are hiding info from us this isn't possible. The greatest virologists in the world can't do it and your teacher thinks you can lol. Does he just want an essay speculating how you would go about it?

Pardon me??

I think that the teacher just want his/her students can create some imaginable viruses by using virology discipline...
Hey, continuing my previous post...you can create a virus which attack Basophils or mast cells. By using certain receptors in those mast cells which is usually get affected by allergen, you can create the resemblance virus' antireceptor. Oh, you also have to create an antireceeptor in order to bind RBC glycoprotein (glycoprotein which determines someone blood type, so the virus is "riding" the RBC to the mast cells place )

So, the mechanism is like this, when a virus is released (via airborne), it will get in into the target's body (usually via respiratory) and riding some RBCs there. Then, when it gets to the mast cell, this virus will change its host into mast cell and starting various mechanisms to replicate and also activate its host (mast cell) to produce massive histamine, leucotrine, prostaglandine, etc to promote a great anaphylaxis syndrome like a sudden vasodilatation which affect in sudden drop in blood pressure so, there'll be a sudden heart attack....
the result, as you all can predict..a sudden heart attack followed by other anaphylaxis syndrome in certain minutes can be lethal for someone..

Ooh...I've create an image of my virus...
