- It is a viral rash that is harmless.
- It does not itch or hurt.
- It can be treated at home.

- Fever Medicine:
- For fevers above 102° F (39° C), give an acetaminophen product (such as Tylenol).
- Another choice is an ibuprofen product (such as Advil).
- Note: Fevers less than 102° F (39° C) are important for fighting infections.
- For all fevers: Keep your child well hydrated. Give lots of cold fluids.
- Pregnant Women - Special Risk:
- The risk of Fifth disease is to the unborn babies of pregnant women. It is not harmful to the woman herself.
- A pregnant woman should see her doctor if she is exposed.
- He will do a test to see if the mother has had the disease. If she has, she is protected.
- If not, the pregnancy will need to be watched closely. Some babies that get it before birth can have problems. Ten percent can have a very low red blood cell count and 2% may die.
- But, birth defects are never a result of this virus.
- What to Expect:

- Return to School:
- Once your child has the "slapped cheeks", they can no longer spread the illness. Also, the lacy rash cannot be spread to others either.
- Your child does not need to stay home from child care or school.
- It can be spread during the week before the rash begins.
- Exposed children should try not to have any contact with pregnant women. This may be hard to know ahead of time.
- Call Your Doctor If:
- Fever above 102° F (39° C) occurs
- You think your child needs to be seen
- Your child becomes worse
