Invasion by germ. This is a sad complication of newborns who are passed herpes virus during delivery. Within 2-3 weeks the virus has invaded their brain tissue causing severe damage, alteration of consciousness and sometimes death.Even if caught early, the infection can produce swiss cheese like holes in normal brain tissue.
