question: Hello Doctor,  My daughter (aged 04 yrs 03 mnths) was infected with Chickenpox virus on the 14th of June, she is used to sleep next to me hugging me most of the time, but i was not infected but my wife had the first blister on the 01st of July, Again, I was looking after her from giving her food uptill cleaning the floor, she is recovered on the 14th of July and my younger daughter (aged 03yrs 01 month) has a blister from the 19th of July. I am still not infected.  My worry is whether I am infected internally and if so, is it dangerous if I do not get blisters visibly on my external body. I feel slight itching on my palm and some parts of the body but nothing visible. What is your expert comment on this.
