Please type your query here...Hi i just discovered my 4 year old has chicken pox and we will be going away for a few days. Will he be able to swim in a swimming pool and be outdoors whilst he has the spots.  <response>: Hi WelcomeI appreciate your concern about your 4-year-old son with chickenpox. It is not advisable for your son to go swimming during chickenpox infection. Chickenpox is highly contagious. If your child has contracted chickenpox, heshe should not go swimming or play contact sports unless all blisters have crusted over. This normally takes place a week after the first rash started. Try to avoid public places, as others may catch the virus, which may be dangerous, especially to those who are pregnant or have a weak immune system. Swimming may also soften the crusts, which may result in a more intense itch and the crusts may fall off early leaving scars. Hope to have answered your query.
