Do you know what CMV is?

Tuesday, June 5th, 2018

June is National Congenital Cytomegalovirus (CMV) Awareness Month. If you are pregnant or planning to become pregnant, it’s important to know about CMV. Here’s why:

CMV is a common viral infection that most of us get at some point in our lives, frequently during childhood. It is usually harmless and rarely causes any signs or symptoms. But if you are pregnant and get CMV for the first time, your baby can get the infection. This can lead to serious illness and lasting disabilities in some babies.

About half of all pregnant women have had CMV in the past. If you’ve already had it, you don’t need to worry about getting it again. Once you’ve been infected, CMV stays in your body for life. Although you can still pass it to your baby, this is rare and usually doesn’t cause any harm to your baby.

What do you need to know?

Most of the time CMV doesn’t cause any symptoms, which means you may not know for sure if you had it or not. Before you try to get pregnant, find out if you’ve ever been infected with CMV. Ask your health care provider for a blood test to know your CMV status. A CMV blood test detects antibodies for this infection. Your body will produce antibodies as a response from this virus. An antibody is a protein your body makes to help protect you from a foreign substance, like a virus.

The test may show:

  • Normal results: This means the test didn’t detect CMV antibodies. You will need to follow precautions to avoid getting infected with CMV.
  • Abnormal results: This means the test has detected CMV antibodies. Ask your provider if the infection happened recently or if it’s an infection that happened a long time ago. If you had a recent infection this can be dangerous when pregnant. Your provider will test your baby for CMV. If you are not pregnant yet, ask your provider how long you need to wait until it’s safe to get pregnant.

How can you get CMV?

You can get CMV by having contact with bodily fluid from a person who carries the virus. You may be more likely than other people to get CMV if you have young children at home, work with young children, or work in health care.

These precautions may protect you from getting CMV:

  • Don’t share food, glasses, straws, forks, or other utensils.
  • Don’t put a baby’s pacifier in your mouth.
  • Avoid kissing young children on the mouth.
  • Do not share personal items that may have saliva, like toothbrushes.
  • Wash your hands frequently, especially after changing diapers or being in contact with children’s body fluids.

Q and A for CMV

Friday, June 23rd, 2017

You may have heard of CMV because it’s the most common virus passed from mothers to babies during pregnancy.

Cytomegalovirus, also called CMV, is a kind of herpesvirus. There are many different kinds of herpesviruses – some of which are sexually transmitted diseases, but others can cause cold sores or infections like CMV.

Q. Who gets it?

A. Many people get CMV at some point in their lives, most often during childhood. Most people with CMV have no signs or symptoms but some may have a sore throat, a fever, swollen glands, or feel tired all the time.

Q. Is CMV dangerous?

A. It can be  – CMV can pass to your baby at any time during pregnancy, labor and delivery and even while breastfeeding. If you have CMV during pregnancy, there is a 1 in 3 chance it will pass to your baby. Eighty percent of babies born with CMV never have symptoms or problems caused by the infection. But about fifteen percent of babies develop a disability such as hearing loss, vision loss or an intellectual disability like trouble learning or communicating.

Q. Can you find out if you or your baby have CMV?

A. Yes. You can have a blood test done during pregnancy to test for CMV. And you can have prenatal tests to see if your baby has CMV. After birth, your baby’s bodily fluids like her urine and saliva can be tested for CMV. Some babies with CMV will have signs or symptoms at birth, but many will appear healthy so testing is important.

Q. Is there any treatment?

A. Yes. If your baby was born with CMV, she may be treated with antiviral medicines to kill the infection. Scientists are working to develop a vaccine for CMV.

In the meantime, remember to always wash your hands well after being in contact with body fluids, when changing diapers or wiping noses, and carefully throw diapers and tissues away. Don’t kiss young children on the mouth or cheek and don’t share food, glasses and eating utensils with children or anyone who may have CMV. These precautions can help you protect yourself and your baby.

Q. If you had CMV in a previous pregnancy, what are the chances you may get it again in another pregnancy? See this post for answers.

If you think you may have (or had) CMV, be sure to talk to your prenatal care provider. See our article to learn more about CMV including treatments.

If I had CMV in a previous pregnancy will I get it again in my next pregnancy?

This is a question we frequently receive through AskUs@marchofdimes.org

2014d037_1623Cytomegalovirus (also called CMV) is a kind of herpesvirus. You can get CMV by coming in contact with bodily fluids (like saliva, semen or urine) from a person who carries the virus. Women usually get infected by having sex with someone who has CMV, but many become infected by having contact with young children who have CMV. As many as 70 percent of children between 1 and 3 years of age who go to daycare may have CMV.

CMV is the most common virus passed from mothers to babies during pregnancy; you have a 1 in 3 chance of passing it to your baby (33 percent). Most babies born with CMV don’t have health problems caused by the virus. However, for some babies, CMV can cause conditions like microcephaly.

Many women who have had CMV in a pregnancy, express concern that they might become infected with CMV again, in another pregnancy. If you’ve already had it, you don’t need to worry about getting CMV again. Once you’ve had CMV, it stays in your body for life. During pregnancy your body produces antibodies against the virus which protect your baby from a more serious illness. In rare cases, you can still pass it to your baby, but it usually doesn’t cause any harm.

If you have concerns, speak with your health care provider.

What you need to know about CMV

Friday, June 13th, 2014

washing handsJune is National Congenital CMV Awareness Month. It is important that all women who are pregnant or thinking about becoming pregnant know about CMV.

What is CMV?

Cytomegalovirus (CMV) is a common viral infection that most of us get at some point in our lives, frequently during childhood. It is usually harmless and does not cause any symptoms. But if a woman becomes infected with CMV for the first time, while she is pregnant, she can pass the virus to her baby. This can lead to serious illness, lasting disabilities or even death.

Why is CMV a concern during pregnancy?

CMV is the most common congenital (present at birth) infection in the United States. Fortunately, most babies born with CMV never have symptoms or problems caused by the infection.

However, some babies born with CMV develop one or more conditions during the first few years of life, such as hearing loss, vision loss, learning disabilities, and intellectual disabilities.

A woman who contracts CMV for the first time during pregnancy has about a 1-in-3 chance of passing the virus on to her fetus. She can pass CMV on to her baby at any stage of pregnancy. However, studies suggest that babies are more likely to develop serious complications when their mother is infected in the first 20 weeks of pregnancy.

How do you get CMV?

You can get CMV by coming into contact with bodily fluid from a person who carries the virus. You may be more likely than other people to get CMV if you have young children at home, work with young children, or work in health care. Most people with CMV have no signs or symptoms, so if you’re a health care or child care worker talk to your doctor about getting tested for CMV before pregnancy to see if you’ve already been exposed to the virus.

How can you prevent CMV?

You can help prevent CMV infection by doing the following:

• Wash your hands well, especially after being in contact with children and body fluids. Wash your hands after changing diapers, wiping noses and picking up toys.

• Carefully throw away used diapers and tissues.

• Don’t kiss young children on the mouth or cheek.

• Don’t share food, glasses, cups, forks or other utensils with young children or with anyone who may have CMV.

Is the March of Dimes conducting research on CMV?

Yes! March of Dimes grantees and other researchers are developing and testing vaccines that may help protect babies against CMV. Recent March of Dimes grantees have been studying how this virus multiplies and spreads in the unborn baby, in order to develop effective drugs that can help prevent disabilities in infected babies.
