Virus
Just the name strikes fear into the heart of everyone, even the strongest and the richest none can escape it’s horrible clutches and it doesn’t just makes us ill but takes our lives and in large numbers too. All viruses are deadly or at least the more stubborn organisms ever known to man that are very hard to cure. Viruses are also known as the ‘living dead’ for their really mysterious ways of sustaining life. They don’t have life functions of their own, and that’s why they are so deadly, they mainly depend on other organisms or hosts to support their life, they attack and invade a host cell like human cell and they take all the energy created by our body to their survival. Unlike bacteria which have some organ functions of their own Virus has none, that’s why even Penicillin the strongest antibiotic is not effective against them.
All the most incurable diseases ever known to man like HIV, Anthrax, Small pox, Polio and many others are caused only by viruses. And they are very stubborn too they can survive for centuries without any food or interaction and can suddenly unleash themselves to kill millions, which makes them completely mysterious in the nature of survival. No one really knows how the great plague of the 1400’s or small pox, or the recent bird flu ever came from or where they went, but they took numerous lives. In recent years bio-technologists have created a virus which are capable of invading and controlling bacterial genome so as to command them to reproduce there own system using the bacteria’s genes. Hope those bio-techno fools stop with bacteria’s alone, else imagine a virus capable of controlling us, we will be roaming around like those ‘Zombies’ then that they show in those creepy movies. Anyway there is only two good news about them, they don’t last long and they are not keen to reproducing. So they are quite dormant most of the time but if we don’t stop playing with nature it is capable of even wiping out the whole human race.
