I can bet that nine out of ten
people reading the title will immediately think I am talking about computer
viruses, worms and assorted online trash. No. I am not. What I am referring to
is the original, the one and only, natural viruses, after which the malicious
computer codes were named- in admiration, in fact. Now don’t get me wrong. Its
not that I am some kind of apocalypse-loving death wish spouting crazy dude
because I declare my love for viruses of the biological variety. But as someone
who has dabbled a bit in the field of microbiology, in a purely amateur, aww
shucks, this is soo interesting kind of way, I do love those nasty buggers, the
viruses, those pieces of raw genetic information (incomplete code, for you
computer-geeks to understand) which, once inside a host, voila, form a complete
and virulent organism, capable of reproducing in millions…
The immediate reason for this
post is two things which happened last week. The first one was, the UN
declaring India Polio free, more about which later. And the second was the preemptory
way we were ordered at the hospital to undergo swine-flu vaccination to prevent
A1H1N1 (the swine-full viruses’ official designation) infection….i hope you
sympathize with me, that I can swallow any number of pills but show me an
injection needle and I will scream and run and hide. At least that’s what I used
to do before I had to start learning to give 50 injections a day…of course to
others. That kinda eased my discomfort with those sharp, long things, but I am
still unable to overcome a tendency to close my eyes tightly when someone
approaches me with a loaded syringe. So, given a choice I would gladly have
taken my chance with swine-flu virus rather than the injection.
The reason, I say so, is not
because I am extra brave or anything, it’s just that the news I am hearing
about the swine-flu virus, THIS YEAR, is that it has mutated to such an extent
compared to the previous year’s version, that although it is more infective
now, with an increase in number of people infected even in summer while
previously it dared not show its head out in the bright sunlight and waited for
gloomy, rainy days, it appears to be attenuated (weakened) to a certain extent,
with less deaths and number of people recovering more, with just a mild disease.
The mutation means that the vaccine which was prepared for last year’s edition
of the virus is just about equal to coloured water now in efficiency, but
people still line up to get the shot purely for mental satisfaction. Because
once you are infected, you have to wait for your body to organize itself and
then clear the virus on its one- this is not bacteria, you cannot kill it with
anti-biotics. This sonafabitch is a virus- too hard to kill.
Which brings me back to the polio
virus. I have a special affinity to the polio virus because of the grief it
caused me in my 2nd year Microbiology class. The topic for the
lecture was Polio and I has as usual made my preparation before the class, so
when the lecturer stated that the Salk vaccination, which is orally administered
is better than the Sabin vaccine which is injectable, I stood up and
contradicted her (I was yet to learn my survival lessons then). This kind of
caused a flap and I was sent to the HOD to defend myself, who instructed me to
report with the proofs of my assertion or not turn up at all, (remember, I was
still a raw 2nd year student then -of a 5 year course).. so next
class, I turned up before the the full inquisition board, the entire department
and proved that my statement was correct, the injectable vaccine was more
efficient (as it prevented infection even from wild strains seen in nature),
but because the government could not afford to inject everyone, it promoted the
easy to use Oral or Drop method vaccine for mass vaccination. It was just
economics (economy of scale) triumphing over science. I was grudgingly vindicated
and re-admitted in class.
So, when the UN declared that India
was Polio-free I was intrigued until I read the report in detail, that says
that there were no new infections of polio (in humans) which we means that the
virus had no human host where it can show its villainy. Current evidence says
that it survives exclusively in humans so the virus should have died a natural
death by now. But has it? These are hardy little buggers and they can literally
hide inside our very cells and strike when we are weak. I wouldn’t be popping
the champagne anytime soon in our fight against the viruses. They were some of
the earliest developed life forms on our planet and they make even the dinos
seem a young species. We just have to learn to coexist with them and of course,
develop efficient anti-virals to deal with infections. But that seems a tall
order, twenty years after HIV erupted into public consciousness, we still don’t
have an effective anti-viral to kill it. And HIV is a baby compared to what’s
out there – Ebola, Hantu, WestNile river etc.
If you are still with me, I can
conclude only by saying that just like an archeologist gets excited by old
bones, I get excited by these miniscule creatures who live all around us,
inside us and affect everything we do, but which most of us have never given a second
thought to. Respectable enemies they are, remember that next time you have a
cold.
