Viruses are those biological entities which are intermediate between living and non-living. Outside the host, they are non-living. Even in non-living state they can survive for millions of years. So, there is no strategy in the world which will prove fatal to virus\' future in the world. Second, viruses have a protein capsid and genetic material. There is no machinery like mitosis, proofreading etc. in their body which will maintain their capsid and genetic material as it is. In fact, their genetic material is highly subject to mutation depending on the host they infect. So, no matter what immune mechanisms human evolve, there is no immune mechanism which will combat these unknown parasites. Humans can only prevent the spread of some viruses, most of which are those that had previously attacked humans; but for new viruses, humans will not be able to develop immune system. So, complete protection is impossible. Third, disease does not confer any kind of protection or survival to the virus. In fact the virus has to leave this host and infect a new healthy host. So, it is true that viruses cause disease accidently, but this does not mean that viruses\' future is at stake because of this. Viruses will survive till the date biological world will survive.

1. Viruses are those biological entities which are intermediate between living and non-living.
Outside the host, they are non-living. Even in non-living state they can survive for millions of
years. So, there is no strategy in the world which will prove fatal to virus' future in the world.
Second, viruses have a protein capsid and genetic material. There is no machinery like mitosis,
proofreading etc. in their body which will maintain their capsid and genetic material as it is. In
fact, their genetic material is highly subject to mutation depending on the host they infect. So, no
matter what immune mechanisms human evolve, there is no immune mechanism which will
combat these unknown parasites. Humans can only prevent the spread of some viruses, most of
which are those that had previously attacked humans; but for new viruses, humans will not be
able to develop immune system. So, complete protection is impossible.
Third, disease does not confer any kind of protection or survival to the virus. In fact the virus has
to leave this host and infect a new healthy host.
So, it is true that viruses cause disease accidently, but this does not mean that viruses' future is at
stake because of this. Viruses will survive till the date biological world will survive.
