hi i had slap cheek while i was pregnant i wrote two advices on it part one is my story and part two is the symptoms and stuff. i can see the links are already added under your q.

Um, if your darling already has slap cheek disease and is showing signs of it, then I'm sorry to say, you will already have it too. 

By the time we show symptoms of any illness, like chicken pox, the flu or slap cheek disease, our bodies have already been fighting it for a while and we have probably passed it on to many people already.

Having checked your daughters age, and they symptoms you have described, it could be the flu or she is getting those 2 year old molars.

Obviously, it is impossible to avoid your daughter so you could try barrier nursing like they would in hospital.  That is face mask, gloves etc, but in the home, just using a hand sanitizer and avoiding kisses etc.

I'll did up the article I've read on slap cheek disease and put it under your question, if someone hasn't beaten me to it.

See your GP if you think that you may have been infected by parvovirus B19 during your pregnancy. A blood test will be carried out to identify antibodies for slapped cheek syndrome from a current, or previous, infection.

If your blood test proves positive for parvovirus B19 in the first 20 weeks of your pregnancy, you will be monitored using ultrasound examinations. This is because the chance of miscarriage is more common in infected women with the virus. A blood transfusion, directly into your baby, may improve the chances of your baby's survival, if foetal hydrops (abnormal fluid in development of baby) is diagnosed.

However, most pregnant women infected with parvovirus B19 normally have healthy babies. Most pregnant women are not at risk from slapped cheek syndrome because they are already immune. There is no evidence to suggest that reinfection or reactivation of the virus will harm your baby, or that there is any increased risk of abnormality occurring in newborns.

If you have blood abnormalities

If you have sickle-cell anaemia, or other abnormalities of the haemoglobin (red blood cells), parvovirus B19 can cause acute, severe anaemia. You may need to be admitted to hospital to receive blood transfusions. Once the infection is controlled, the anaemia should settle down. Children may be at particular risk if they already have hereditary anaemia (a disorder that runs in the family), such as hereditary spherocytosis.

If you are immuno-deficient

People with a weakened immune system (immuno-deficiency) may also need to be admitted to hospital for treatment as they may develop chronic anaemia due to slapped cheek syndrome. Speak to your GP or specialist if you suspect you are feeling unwell due to a virus.

Arthritis

Arthritis can develop after being infected with parvovirus B19, affecting the small joints of your hands and feet, with the symptoms similar to those of rheumatoid arthritis. Arthritis is more common in adults and may persist for months, although symptoms usually disappear within a few weeks. However, if you experience arthritis as a result of slapped cheek syndrome, it is unlikely you will have permanent damage to your bones or joints.
