Hi Pricilla,
It is not serious for the kids. both of mine have had it. But what did happen is I also got it but it can be very different in adults. My feet started itching severly and my hand swelled up and were very sore to move. I ended up going to the doctor and was tested for a couple different things but it came back that I had fifth disease. The good news is I should never get it again.
