Hepatitis and Pregnancy: What to KnowTeresa Tran
Hepatitis C (HCV)
You catch this virus through contact with blood. Today, most Americans get it after sharing needles or other tools to inject drugs. HCV is showing up in more and more pregnant women, probably because of the sharp rise in heroin and prescription drug abuse.
How HCV Affects Your Baby
One in 20 infants born to mothers with HCV gets the virus. That can happen in the womb, during delivery, or after the baby is born. The disease usually does not affect your baby before birth. Your child can’t catch the virus from your breast milk, but check with your doctor if your nipples are cracked or bleeding since the virus spreads through blood.
There’s no way to prevent the virus from spreading to your baby. You don’t need to deliver by cesarian section just because you have hepatitis C.
Test and Care
Most doctors recommend testing a baby for hepatitis C after they’re 18 months old. Checking before then isn’t useful because a very young infant still carries his mother’s antibodies to HCV. A test would show that the baby is infected when he might not be.
What You Can Do
Doctors don’t regularly test for hepatitis C during pregnancy. If you have any reason to think you might have it — because you’ve used drugs or had sex with someone who has the disease, for example — get tested. Do it even if you feel fine. Four out of 5 people with HCV don’t have any symptoms.
Your doctor likely won’t treat you for hepatitis C while you’re pregnant because the medications can cause birth defects.
Hepatitis B (HBV)
Like hepatitis C, this virus can cause serious infections that damage the liver. You can pass both viruses to your baby before, during, or after vaginal or C-section delivery. The difference with hepatitis B is that:
- You can get it not only through blood, but less likely through semen, vaginal discharge, saliva, and other body fluids.
- A vaccine can prevent HBV infection, and most babies get it at birth.
- Doctors regularly test pregnant women for it.
- If you’re infected, the chances of passing it to your baby are much higher than for hepatitis C. If you’ve gotten sick with hepatitis B in the last 6 months, what your doctor may call acute infection, your newborn has a 90% chance of getting it. If you’ve had the infection for longer, called chronic hepatitis B, that chance drops to 10-20%.
Care After Delivery
There’s no cure for hepatitis B. But if your newborn gets his first dose of the hepatitis B vaccine and another shot called hepatitis B immune globulin within 12 hours, he has better than a 90% chance of never getting the virus. All babies routinely get the first shot. But they get the immune globulin only if the mother has or is suspected of having HBV. The baby also needs two remaining doses of the vaccine over the next 6 months to get maximum protection.
You can safely breastfeed if you have hepatitis B.
Hepatitis A (HAV)
But HAV can make you go into labor too early, especially if you get the virus after your first trimester. It can lead to other dangerous complications, such as causing your placenta to separate from your uterus before your baby is ready to be born.
What You Can Do
Hepatitis A is more common in places without clean food and water and with poor sanitation systems. If you are pregnant or of childbearing age, consider getting an HAV vaccine before you visit those areas. If you’ve eaten at a restaurant that reported a hepatitis A outbreak, see your doctor. A vaccine can help protect you and your unborn baby. But you need to get it within 2 weeks of getting the virus.
