If a pregnant woman is exposed to parvovirus B19, obtain IgG and IgM serology as soon as possible. [25, 22] Positive IgG results and negative IgM results indicate past infection (no risk to fetus). Positive IgG and IgM results indicate infection within the last 7-120 days (possible risk to fetus).
How long is IgM positive parvo?
Parvovirus B19 IgM usually appears within 2 to 3 days of acute infection and may persist up to 6 months.
How long do parvo IgG antibodies last?
Markers of Parvovirus B19 infection

Can parvovirus B19 be cured?
For an uncomplicated parvovirus infection, self-care treatment at home is generally sufficient. People with severe anemia may need to stay in the hospital and receive blood transfusions.

Does parvovirus in humans go away?
Treatment. Fifth disease is usually mild and will go away on its own. Children and adults who are otherwise healthy usually recover completely. Treatment usually involves relieving symptoms, such as fever, itching, and joint pain and swelling.

Why is IgM positive and IgG negative?
If IgM antibodies are positive and IgG antibodies are negative, it may be an early stage of the infection where only the initial IgM antibodies have been produced but the IgG antibodies have not yet been produced. Testing may be repeated to confirm production of IgG antibodies.
How long is parvo recovery?
