10 Infections That Can Cause Miscarriage In A Pregnant Woman

10 Infections That Can Cause Miscarriage In A Pregnant Woman

Some infections that develop during pregnancy can lead to miscarriage, preterm labor, or birth defects.

Pregnancy is a very sensitive time for a woman. She has to pay extra attention to her health not just for her, but for her baby too. Paying attention to her health includes eating right, taking prenatal vitamins, and preventing infections. Because there are infections that can cause miscarriage, terminating the pregnancy.

Most of the common infections that can happen to you during pregnancy, may cause no major problems. Infections of the skin, urinary tract, and respiratory tract are generally mild. But some infections can be passed to the foetus before or during birth and damage the fetus or cause a miscarriage or premature birth. Have a look at some of the infections that can cause miscarriage during your pregnancy.

Infections That Can Cause Miscarriage

Chlamydial infection is a very common sexually transmitted disease. Because the infection frequently causes no immediate symptoms, it may infect more people than experts can account for. In women, chlamydiae account for virtually all of the cervical infections that produce pus and that are not caused by gonorrhoea. The infection may cause a miscarriage, preterm labour, and premature rupture of the membranes. It can also cause eye inflammation (conjunctivitis) in newborns.


Gonorrhoea is a sexually transmitted disease from the bacteria Neisseria gonorrhoeae. These bacteria infect the lining of the urethra, cervix, rectum, and throat; or the membranes that cover the front part of the eye (conjunctiva and cornea). People usually have a discharge from the penis or vagina and may need to urinate more frequently and urgently. If a pregnant woman gets it in the early stage of pregnancy, it could cause a miscarriage. If in later pregnancy, the bacteria can spread to the eyes of the foetus during birth; causing conjunctivitis in the newborn.

Zika Virus Infection

This infection in a pregnant woman can cause the baby to have a small head. The head is small because it does not develop normally. Zika virus infection can also cause eye abnormalities in the baby. The Zika virus spreads through mosquitoes, but it can also spread through sexual intercourse, through blood transfusions, and from a pregnant woman to her baby before or during birth. In the early stages of pregnancy, treating the infection could lead to a miscarriage.

German Measles

Also known as rubella, this infection can cause problems, particularly inadequate growth before birth; cataracts, birth defects of the heart; hearing loss, and delayed development. Rubella is a contagious viral infection that typically causes mild symptoms, such as joint pain and a rash; but can cause miscarriage or severe birth defects if the mother becomes infected with rubella during pregnancy. Rubella used to be the "German measles" or "3-day measles" because it causes a rash similar to the rash that measles causes. But a different virus is responsible for it.

Cytomegalovirus infection

This is a common herpes virus infection with a wide range of symptoms: from no symptoms to fever and fatigue (resembling infectious mononucleosis); to severe symptoms involving the eyes, brain, or other internal organs. In a pregnant woman, the disease can cross the placenta and damage the foetus’s liver and brain; and the foetus may not grow as much as expected. This may lead to chromosomal issues and ultimately a miscarriage.

Chickenpox (Varicella)

When you have chickenpox in pregnancy, your risk of miscarriage increases. The infection may damage the eyes of the baby or cause defects of the limbs; blindness, or intellectual disability. And the foetus’s head may be smaller than normal.


With this infection, the single-celled protozoan parasite Toxoplasma gondii is responsible. Usually, the infection does not cause symptoms, but some people have swollen lymph nodes, fever; a vague ill-feeling, and sometimes a sore throat or blurred vision and eye pain. In people with a weakened immune system due to AIDS or another condition, toxoplasmosis can reactivate, usually affecting the brain. It is a protozoal infection and it may cause a miscarriage, death of the foetus, and serious birth defects.


It is a bacterial infection that increases your risk of preterm labour, miscarriage, and stillbirth. Newborns can get infected, but symptoms may be delayed until several weeks after birth. Listeriosiscomes from the gram-positive bacteria Listeria monocytogenes, usually when a person eats contaminated food.

Bacterial Vaginal Infections

Infections of the vagina (such as bacterial vaginosis) may lead to preterm labour, miscarriage or premature rupture of the membranes containing the foetus.

Urinary Tract Infection

This disease increases the risk of preterm labour and premature rupture of the membranes containing the foetus.

How To Treat Diseases That Lead To Pregnancy Loss


Sometimes drugs, depending on the balance of benefits and risks.

To determine whether to treat you with antimicrobial drugs, your doctors will weigh the risks of using the drug against the risks of the infection.
