Toxoplasmosis is an infection caused by a parasite called Toxoplasma gondii, often found in cat feces. While it is a rare condition, it can have serious implications, especially during pregnancy. The parasite can also be contracted through undercooked meat or contaminated fruits and vegetables. If you’ve had cats for a while, you might have been exposed and developed immunity without even knowing it.
Symptoms of Toxoplasmosis
Symptoms can vary widely, and some people may not experience any at all. Common signs include:
- Fatigue
- Fever
- Swollen lymph nodes
- In some cases, there may be no symptoms at all
How Common is Toxoplasmosis?
Toxoplasmosis is more prevalent in warm, humid climates. In fact, over 50% of the population in parts of Europe, Africa, South America, and Asia may carry the infection. For instance, France has a higher rate due to a cultural preference for undercooked or raw meat. In the United States, the incidence is lower, affecting about 1 in every 1,000 to 8,000 newborns. Environments like veterinary clinics and meat processing plants are hotspots for transmission.
Impact of Toxoplasmosis on Pregnancy
For women who are not immune, exposure to Toxoplasma gondii can lead to fetal infection. According to the Teratology Information Specialists Organization (TIS), if a mother contracts the infection between weeks 10 and 24 of her pregnancy, there’s about a 5.6% risk of severe complications for the newborn. Potential effects on the baby can include:
- Premature birth
- Low birth weight
- Fever
- Jaundice
- Retinal abnormalities
- Developmental delays
- Abnormal head size
- Seizures
- Brain calcifications
Interestingly, while the risk of infection increases in the third trimester, the likelihood of serious damage diminishes since most critical development has already taken place.
Preventing Toxoplasmosis
To minimize the risk of infection, consider the following precautions:
- Avoid contact with cat feces; ask someone else to change the litter box.
- Keep cats off counters and dining surfaces.
- When dining out, order meat well-cooked.
- Wash your hands thoroughly after handling raw meat or interacting with your cat.
- Clean and sanitize kitchen counters regularly to limit contamination.
Diagnosis of Toxoplasmosis
Healthcare providers typically screen for toxoplasmosis immunity before pregnancy or during the initial prenatal visit. A blood test can confirm past exposure. If diagnosed during pregnancy, antibiotics may be prescribed to reduce the risk of severe complications for the baby. In certain cases, a procedure called cordocentesis can help determine if the fetus has been infected.
