A virus, mutation. This words stated in your writeup has made me picture some thing extraordinary for medical personnel. Just imagine a virus behaving in a particular form and when detected in another angle it behaves in another form, I think this has made tackling AIDS very difficult. We must not disregard the fact that AIDs is still in existed by carrying out activities that excites it spread. My dear friends, this platform has really help people like us to understand some of this concept better especially when health worker like you are giving writing on topics like this. It has really helped. Demolishing the virus is not a small feat, that is why i advice people to refrain from activities that leads to this disease and take precaution that will help curtail the rate of the disease spread. Goodluck💕💕
