Bird-Flu – Evolving/Changing

It has long been known that viruses, though not able to replicate themselves have the uncanny ability to genetically modify the way they work as they spread through a community. Many questions are in need of answers, such as why some people get horribly sick and some don’t. Or how the virus evolved to jump the species barrier in the first place.

Scientists have gained ground and have come out with vaccines that used to be quite rare but have stepped up production making it more accessible to more people. The problem with viruses is their diverse and ever evolving genetic make-up that makes them hard to treat. Along with evolving bacteria known as MRSA which are not treatable with common antibiotics, they are a challenge indeed in the never ending battle within the human body.
