What kind of doctor treats Congenital Mumps?

An infectious disease specialist treats infections caused by germs like viruses and often helps care for pregnant women with mumps. A pediatrician usually follows the baby after birth and orders hearing tests if needed. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.

What it is

Congenital mumps refers to problems a baby may have at birth when the mother gets a mumps infection during pregnancy. Mumps is a virus spread through saliva and coughing that usually causes swollen cheeks and fever. The term once described a rare pattern of birth problems linked to infection early in pregnancy. Today it is very rare in the United States because most people are vaccinated.

Symptoms

Mumps in the first three months of pregnancy has been linked in some studies to a higher chance of miscarriage. Older reports also linked early infection to hearing loss or low birth weight, but these problems are uncommon. Most babies born to mothers who had mumps during pregnancy are healthy. Doctors can check a baby's hearing and growth after birth.

Causes and who gets it

The cause is the mumps virus passing to the baby during pregnancy, with the risk highest in the first trimester. Outbreaks can still happen even in well vaccinated communities, and a pregnant woman who has never had the vaccine or the infection has the highest risk.

How doctors diagnose it

Doctors diagnose mumps in the mother through her symptoms and a lab test, often a mouth swab or blood test. If a pregnant woman has mumps, her doctors will watch the pregnancy closely, then check the baby's hearing and growth after birth. There is no single congenital mumps test.

Treatment

There is no medicine that kills the mumps virus, so treatment focuses on comfort and rest. Mothers may be told to rest, drink fluids, and take medicine for fever or pain. For the baby, early help with hearing devices and speech therapy can make a big difference.

When to see a doctor

A pregnant woman should call her doctor right away if she has swollen cheeks, fever, or ear pain. Anyone not vaccinated who has been near a person with mumps should also call. Parents should tell the baby's doctor about any mumps infection during the pregnancy.

How a direct primary care or concierge doctor fits in

A direct primary care doctor is paid a flat monthly fee instead of billing insurance; a concierge doctor usually charges more and often works with insurance. Either can be a good first stop, with longer visits that help when a patient has questions. If mumps is suspected, these doctors refer patients to a specialist.

Common questions

Can mumps during pregnancy harm the baby?

It can, but harm is not common. Infection early in pregnancy has been linked to miscarriage and, in some reports, hearing problems. Most babies born after mumps in pregnancy are healthy.

Can a pregnant woman get the mumps vaccine?

No. The mumps vaccine is a live vaccine, which means it contains a weakened form of the virus. Live vaccines are not given during pregnancy. Women are advised to be protected before becoming pregnant.

How is mumps spread?

The virus spreads through spit and droplets from coughing, sneezing, or sharing cups. A person can spread it before they even look sick.

What should a baby be checked for after mumps in pregnancy?

Doctors usually check the baby's hearing and watch growth and development. If a problem is found, early therapy can help the child learn and communicate.
