How Common Is Miscarriage After Fifth Disease?
In rare cases, a miscarriage after fifth disease can occur. It appears that miscarriages happen in less than 5 percent of all women who are infected with parvovirus B19 while they are pregnant. A miscarriage after fifth disease appears to be most common during the first trimester. Such a miscarriage is most commonly due to nonimmune hydrops fetalis, a condition which causes severe anemia (low red blood cells) and congestive heart failure.

There is no evidence that parvovirus B19 infection in the mother, while she is pregnant, causes birth defects or mental retardation.
