My Lo (10 mths) has this one blister at hand. I suspected is the sign of chicken pox. Is this chicken pox or just because his hand is dirty and it's a dirt related blister?

Oh dear, please please please go get medical advise. Do not take the risk and wait further!!!

I think should be HFMD... My two boys just recover. Is there blisters anywhere else?

Does look like the start of chicken pox. Pls go to the pd to check it out pls
