CMV is a worldwide type of virus which affects 60-80 % of the human population in developed countries. The virus is spread through saliva or urine and in healthy individuals can survive under the immune system control without any visible symptoms. The CMV life strategy is to integrate DNA into the genome of the host cells and escape the mechanism of natural immunity.
