Is there a way to stop a virus from mutating?
« on: 16/09/2007 08:15:59 »
these days, there are many new viruses which spreads everywhere. What i was wondering about is that is there a way to stop these virus for mutating because if they keep mutating, probably one day they will reach a certain point where no vaccine or medication could stop them from spreading. ;D

All life mutates - it is a condition of life (there is debate about whether viruses are technically life forms, but they depend on the same genetic mechanisms as the rest of life).  In fact, if viruses did not mutate, they would not have survived this long, and we would not be asking these questions today (they would have long ago become extinct).

Because viruses are very primitive life (as I said, it is a borderline question as to whether they are life at all), they lack a lot of the repair mechanisms that most other living organisms use to limit the rate of mutation, so they mutate more frequently than other organisms.

As for their ever being able to mutate to a point where no vaccine could be used against them - if they could have done this, they would have done this; so the fact that as far as we are aware they never have done this means they would not be able to do this (the closest any virus has got to this is the HIV virus).

All that vaccination does is to use the bodies own defences, that it will naturally use to defend itself against the live virus, but it merely gives that defence mechanism an early warning of what viruses to expect.  If the vaccination were to fail, that would imply that the bodies own defences against the virus would be useless.  If this had happened in the past, then it is clear that we as a species would already be extinct - so it is clear that it has not happened in the past.  In fact, it is not in the viruses own interest to do this - since a virus needs a host to live on, and if it kills all of its potential hosts, then the virus itself dies (it is OK to kill a percentage of its hosts, but if it kills them all, then it itself will die).

Yes. And mutation is such that the new horrible diseases are formed.
AIDS virus is relatively dangerous.
Some viruses are still more dangerous.
There are genetic diseases which can not cured by any medicine.
Pennis hyper erection disease.
Chicken Pox. Chicken Pox is hereditary.
I think some viruses might have found way into chromosomes.

Most viral diseases cannot be 'cured' by medicines, although medicines can help alleviate the symptoms, and many viral diseases are self limiting, so if you can alleviate the symptoms then the body will cure itself.

Chicken Pox. Chicken Pox is hereditary.

You have started a separate thread on this matter at Chicken Pox- A hereditary disease?, and I have answered this point there, but it is just plain wrong.

I think some viruses might have found way into chromosomes.

This is certainly true (for all animals, not only for humans), and is particularly true of retroviruses (of which HIV is an example).

Viruses tend to mutate due to naturally occuring mutations during replication. HIV virus mutates once per replication cycle when reverse transcriptase copies genomic RNA into DNA which is why the 1st HIV drugs were reverse transcriptase inhibitors

Viruses will always mutate and yes dkv, you're right viruses have found their way into chromosomes - considerable amounts of human DNA is made of old retroviral fragments.
