Dangerous infections to avoid during pregnancy

Dangerous infections to avoid during pregnancy

Some complications during pregnancy are independent of your will and what you do. But there are problems that can be easily prevented by paying close attention to what you eat in particular, but also to other aspects of this unique period. Here are some of the infections that can endanger the task you have to stay away from at any cost!


Toxoplasmosis is an infection caused by a parasite found in feces of cat, soil, meat or unpasteurized milk.

The risks associated with toxoplasmosis are extremely high for babies. When the parasite is transmitted to the fetus it is called congenital toxoplasmosis and may include the following problems that may develop in the fetus:

  • abortion;

  • delays in growth and development;

  • hydrocephalus;

  • epilepsy;

  • mental retardation;

  • reduced muscle tone;

  • vision disorders, until blindness;

  • deafness;

  • death of the fetus, etc.

Although it is a fairly rare infection in pregnancy, you can be easily exposed by simply having a cat and not knowing how to take care of it so that you do not endanger your pregnancy. Here's how you can avoid toxoplasmosis:

  • does not touch the cat's sand, but puts someone else to do it or use gloves when doing it;

  • use gloves when gardening;

  • Wash fruits, vegetables and other products that you consume in a raw state;

  • wash your hands well after you put your hand on the meat and make sure it is cooked well;

  • do not drink unpasteurized milk.


Salmonella is an infection caused by a bacterium and is manifested by nausea, vomiting, severe diarrhea, abdominal pain and fever. This is mainly caused by the consumption of:

  • sufficiently negated meat;

  • eggs;

  • unvaccinated poultry;

  • unprocessed milk.

Salmonella infection can make you feel very bad, and in rare and very severe cases it can affect your belly. Salmonella type S is the only type of infection with this bacterium that can be transmitted to the fetus. Although fetal contamination with S-type salmonella is very rare, the risks of pregnancy are extremely high:

  • miscarriage;

  • premature birth;

  • the birth of a dead child.

Contamination is very easy through the consumption of food products infected with this bacterium:

  • fresh and unpasteurized milk;

  • insufficient raw or cooked meat;

  • insufficiently prepared eggs;

  • whipped cream;

  • canned.

Avoiding the consumption of these products, as well as adopting appropriate hygienic conditions (hand washing, fruit and vegetables thoroughly washed, cooked properly, etc.) are sufficient to avoid contamination. In case of infection in pregnancy, antibiotic treatment is indicated.

Group B strep

Group B streptococcus infection is a bacterium that can be hosted by the body without causing problems. A lot of pregnant women and not only are carrying this bacterium. However, if transmitted to the fetus during pregnancy, it may cause:

  • sepsis;

  • pneumonia;

  • meningitis.

During pregnancy, your baby may come in contact with this group B streptococcus and be infected at birth. Hamolithic beta or streptococcal B infection is the most common neonatal infection with early onset. It appears in the baby within 48 hours after birth. If not treated properly it can cause serious problems in the development of the child and even death.

You can prevent this infection in the baby during pregnancy by a simple test performed between weeks 35-37 of pregnancy. It determines whether or not you are a carrier of this bacterium. If you are found to be a carrier, go for an intravenous antibiotic treatment at least 4 hours before the baby is born. This measure reduces the risk of transmission and infection of the newborn. If this measure fails, antibiotics can also be given to the newborn as a preventive measure.


Listeriosis is an infection caused by the bacterium Listeriza monocytogenes, which especially affects pregnant and newborns, as well as others who have a weak or insufficiently developed immune system. This can be found in:

  • ground;

  • animal faeces;

  • contaminated food (unpasteurized milk, cheese or raw and sufficiently negated meat).

In the most serious cases of pregnant women infected with this bacterium, side effects can be found such as:

  • miscarriage;

  • premature birth;

  • the birth of a dead child.

The prevention of this dangerous infection during pregnancy is done by paying greater attention to the diet and avoiding as much as possible some products with high risk of contaminating you through their consumption:

  • avoid soft, creamy cheeses as well as moldy ones;

  • avoid liver stain, even vegetable;

  • do not eat dairy products containing unpasteurized milk;

  • wash fruits and vegetables well before consumption;

  • cook the meat very well, preferably by boiling.

If you have consumed such products and you feel fever, muscle pain, nausea and vomiting or severe gastric pain, go to your doctor urgently. The infection is detected by performing a blood test and treated with an antibiotic.


It is also an infection caused by the consumption of food or water contaminated with Campylobacter jejuni. If you are infected with this bacterium you may experience the following symptoms: fever, stomach cramps, muscle aches, vomiting, nausea or severe diarrhea.

Consumption of infected poultry meat is responsible for more than half of the cases. The second source of infection is contaminated water, and otherwise unpasteurized dairy products, as well as foods that have been unpacked or not properly washed may be potential risk factors.

It is a very rare infection during pregnancy, but if you do not get in contact with one of the sources of infection, you can risk the bacteria being transmitted intra-placenta to the fetus, and the risks, although low, are:

  • miscarriage;

  • premature birth;

  • the birth of a dead child.
