Bacterial / Viral Infections and Pregnancy Loss

Chronic genital infections and sexually transmitted diseases can increase risk of miscarriage, but certain other short-term illnesses may cause pregnancy loss also. Learn about symptoms and treatment in order to reduce risk.

Infection and Pregnancy Loss
Many infections have been linked to pregnancy loss, from sexually transmitted infections to infectious viral infections like parvovirus. This article contains a list of some of the most common infections thought to cause pregnancy loss.

Chorioamnionitis
Chorioamnionitis is a potentially serious condition in which the amniotic fluid and pregnancy membranes become infected by bacteria. With chorioamnionitis the baby may need to be delivered at once, and in some cases this condition can lead to loss of the baby.

What to Do About a Fever in Pregnancy
When you have a fever in pregnancy, call your doctor right away. Fever won't necessarily cause a miscarriage but your doctor might want you to use Tylenol or other fever reducers.

Cytomegalovirus (CMV) and Pregnancy
Cytomegalovirus, often abbreviated as CMV, is a very common virus in the general population. About half of pregnant women have been infected prior to pregnancy, but when moms catch CMV for the first time during pregnancy, the baby can suffer serious complications.

Bacterial and Viral Infections Linked to Miscarriage / Pregnancy Loss

Some viral and bacterial infections increase the risk of pregnancy loss. While a few infectious illnesses are well-documented risk factors for miscarriage, some newer literature is indicating that even a few common vaginal infections can mean an increased risk of miscarriage.

Some of these infections are limited in course but others can be chronic. Remember that if you are concerned that y…

Sexually Transmitted Diseases and Risk of Miscarriage or Stillbirth

If you have a sexually transmitted disease (STD), or if you have symptoms that you are worried about, it is always a good idea to talk to a healthcare provider. Having an untreated STD during pregnancy can mean an increased risk of miscarriage or preterm delivery, although the exact risk varies by the type of STD.

Does Gonorrhea Cause Miscarriage?
Learn whether gonorrhea during pregnancy can cause miscarriage, ectopic pregnancy, preterm labor, or other pregnancy complications.

Can Herpes Cause Miscarriage or Later Pregnancy Loss?
Undetected genital herpes has been tied to recurrent miscarriages by some research but doctors don't know whether HSV actually can cause miscarriage. The biggest risk of herpes during pregnancy is that the virus could be passed on to the baby during birth.

Can Viral Hepatitis During Pregnancy Lead to Miscarriage?
Acute viral hepatitis may increase the risk of preterm labor or other late pregnancy complications but generally does not seem to increase the risk of miscarriage or pregnancy loss, even for Hepatitis B and Hepatitis C carriers. The exception is Hepatitis E, which can lead to pregnancy loss and sometimes death of the mother when acquired during pregnancy.

Bacterial Vaginosis Symptoms
Some research has tied bacterial vaginosis to increased risk of late miscarriage and preterm delivery, but how can you know if you need to be tested? Here are the signs and symptoms of bacterial vaginosis.

Does Syphilis Cause Pregnancy Loss?
Having a syphilis infection during pregnancy means a very high risk of stillbirth or infant loss. Babies can also contract the infection during pregnancy or birth, leading to life threatening complications and developmental problems. Be sure to seek treatment if you suspect you have syphilis.

Does HIV Infection Cause Miscarriage?
Although it used to be that women with HIV had an increased risk of miscarriage, modern drugs seem to have reduced the odds of pregnancy loss to no higher than the average risk for moms without HIV.

Can Chlamydia Infection Cause Miscarriage?
Chlamydia, a common sexually transmitted disease, may increase the risk of ectopic pregnancy and/or miscarriage if not treated.

Can Catching a Cold or Flu During Pregnancy Cause a Miscarriage?
A few types of viral and bacterial infections during pregnancy are linked to miscarriage, but should pregnant women worry about the common cold or the flu? The two infections have never been definitively linked to miscarriage but they might cause other complications.

Can Exposure to Chickenpox During Pregnancy Cause a Miscarriage?
Exposure to infections such as chickenpox (a.k.a. varicella) during pregnancy can bring increased risks. Some infections can lead to miscarriage or stillbirth. The chickenpox virus is not likely to cause a miscarriage, although other problems can occur if pregnant women are exposed.

I Had an MMR Vaccine Before I Knew I Was Pregnant. Should I Worry?
Doctors usually advise women to wait at least a month after a rubella or MMR vaccine before trying to get pregnant, but sometimes women get the vaccine without knowing they are pregnant or they accidentally become pregnant before a whole month has passed. Will rubella vaccination during pregnancy mean an increased risk of miscarriage or birth defects?

Can Exposure to Rubella During Pregnancy Cause a Miscarriage?
Even though it's rarely dangerous for most people, getting rubella during pregnancy can cause problems. Research shows a high rate of congenital birth defects when moms contract rubella during the first trimester, and sometimes the rubella during pregnancy can cause miscarriage.

Will Exposure to Fifth Disease During Pregnancy Cause a Miscarriage?
Exposure to fifth disease (aka parvovirus B19) during pregnancy is a common concern, given a link between fifth disease and miscarriage, but in truth only about 5% of women who contract parvovirus B19 during pregnancy experience complications.

Bacterial Vaginosis and Risk of Miscarriage
Bacterial vaginosis is an imbalance of bacteria in the vagina. Symptoms can include an unpleasant fishy odor and a thin gray or white vaginal discharge. Some research suggests that bacterial vaginosis in pregnancy can cause second-trimester miscarriages and increase the risk of preterm delivery.

Did My Cat Give Me Toxoplasmosis and Cause My Miscarriage?
Many women worry that their cats might cause a miscarriage by transmitting toxoplasmosis, a bacterial infection associated with miscarriage. But the risk many people associate with cats is usually overblown.

Can Food Poisoning Cause a Miscarriage?
Food-borne infections, such as listeriosis or salmonella, are a potential cause of miscarriages. During pregnancy, avoiding foods known to be risky is one way to protect yourself from pregnancy loss.

Which Foods Should I Avoid to Reduce Miscarriage Risk from Food Poisoning?
Food poisoning from bacteria such as Listeria, Salmonella, and E. coli can be a risk factor for miscarriage and stillbirth. Learn which foods pose a risk for these food-borne infections in order to reduce your pregnancy loss risk.

Which Cheeses Should I Avoid Eating When I'm Pregnant?
You have probably heard that you should avoid unpasteurized dairy products during pregnancy, but do you know which specific cheese products pose a miscarriage risk from possible contamination with Listeria (the bacteria that cause listeriosis)?

Can a Fever Cause a Miscarriage?
Fever during pregnancy can increase the risk of neural tube defects, but right now there is little evidence that fever can cause first-trimester miscarriages.
