If you've had chickenpox in the past, then you can't get it again and your baby will be fine. If you didn't have chickenpox or if you're not sure, you should see your doctor right away. Your doctor will test your blood to see if you're immune. Many people who don't remember having chickenpox are immune anyway. If your blood test shows that you're not immune, you can take medicines to make your illness less severe and possibly help protect your baby from chickenpox.
Fifth disease is common in children.
Half of all adults are susceptible to fifth disease and can catch it from children. Children with fifth disease can get a rash on their body. They may have red cheeks that look like they've been slapped. They may have sore joints. If the anemia is bad, the baby could die.
