Hello Mr. Eliko, well I must say your trip to the UK certainly seems to have left you an interesting and philisophical mood
Rest assured, I have not found any of the above comments about me anything but amusing and just a bit of fun
You may have noticed some other comments on this forum lately about me which were certainly far from "a bit of fun", but that is old news now.
It is, of course, your prerogative to not discuss what you've been up to in the UK I was just interested, that's all.
Regarding your questions, well I shall answer as follows:
1) A virus, to the best of my knowledge, is a single-celled organism and one of the simplest and likely first organisms to appear on the planet. Like all organisms it's objective (according to science) is to replicate itself in order to continue the survival of the species. It does this by invading other organisms, and taking over the genetic make up of their cells and replacing them with it's own, thus turning the cell into a factory to generate new viruses and replicate the process. I am an engineer, and a bit of a physicist, rather than a biologist; hence my knowledge of the actual process in which this happens is lost somewhere back in the midsts of time.
2) A virus is formed either from a single viral cell, in the process I describe above, or from a mutation. Given that the virus can regenerate so quickly, mutations can happen at a fast rate. According to Darwin's theory of natural selection (if one believes it), then the mutations which will prove beneficial are those which would lead to it being easier for the virus to survive and regenerate. Given what I described in 1), above, then the successful mutations will be those which enable the virus to more easier infect its hosts. These hosts would typically be the same species of organism but occasionally a mutation may occur which makes it possible for the virus to jump species, and when this happens I believe that is when we give say there is a new form of the virus? (And it gets another number). As for how viruses were formed originally, I don't know I suppose they evolved - probably quite early on - from the "primeval soup" which was supposed to be how life was created (if you believe that theory - other theories supported by conventional science (as opposed to religion) are that viruses were amongst the first organisms along with bacterium to arrive e.g on comets from other worlds).
3) Short answer - no. First off, 'flu (influenza) is a whole collection of viruses (a new strain appears every year i believe), which produce the same symptoms, similar to the common cold group of viruses (of which I have been suffering the last few days, thanks for your concern, I am feeling a lot better now although not completely recovered
) but more severe in nature. Also, my understanding is that the viruses causing flu mutate frequently, whereas cold viruses do not (or presumably do not tend to in anything like the severity or the time frame). I don't know why that is, but I seem to remember reading that there are only a fairly constant number of "common cold" viruses in existence, something like several hundred I think. I am again not sure, but I think the flu virus infects the back of the throat and the cold virus the nasopharynx?
Anyway, I believe "bird flu" is so called because it gives birds similar symptoms to those that humans get when they get a cold or flu. A number of animals - I
think all mammals - can get colds, and when they do the symptoms are similar to humans, such as running/sore nose, puffed up eyes, sneezing, etc. I've seen it before in pets I used to have (Gerbils). I presume in birds some of the symptoms are similar, hence the name. Unfortunately the H5N1 virus seems to be fatal in nearly all cases for birds, whereas
most flu viruses tend to not be fatal in humans.
One thing I am not so sure on - which I would have to go and look up - is the way in which this H5N1 seems to be able to infect humans as well, presumably without a mutation. I cannot recall the symptoms in humans - I presume it is similar to flu - although this one seems a particularly virulent strain as I understand it is fatal in most cases.
I am guessing here, and as I say it is not my business, but from what you have said I am thinking you are somehow involved with research into the "bird flu" virus and how it might evolve into an airborne strain that can infect humans, and maybe you travel around the world to outbreaks of it after they have occurred?
I must say, I do have a slight interest in these sort of things ever since I read "The Hot Zone" (sorry, can't remember the author) some years ago, which was what the film "Outbreak" was based on. Not
that much of an interest, I do not want my "fans" to think I am a sad geek LOL! But it is interesting that an airborne version of a slower-killing Ebola virus might be just lurking in the African jungle somewhere, waiting to kill us all... Domesday scenario number N, where N is a large number
