Understanding Causes

Who is most at risk for contracting toxoplasmosis?

and Health

Toxoplasmosis is a disease caused by the parasite Toxoplasma gondii, which is commonly found in cats, but has been known to affect humans as well. It is typically spread through contact with contaminated food, soil, water, or contact with infected cats. Symptoms vary greatly depending on the individual’s age, weight and overall health.

What Are the Causes of Toxoplasmosis?

The parasite’s primary transmission method is through contact with cat feces, which may contain the parasite. It is estimated that up to 1 in 6 individuals worldwide have been infected with the Toxoplasma gondii parasite.

Other common sources of infection include:

  • Contact with raw, undercooked or contaminated beef, pork, ham, or game
  • Coming into contact with contaminated soil or water
  • Consumption of contaminated fruits or vegetables

People can also be infected from consuming unpasteurized milk or eating raw eggs. Individuals who are pregnant or with weakened immune systems are at higher risk for developing toxoplasmosis.

What Are The Symptoms of Toxoplasmosis?

The symptoms of toxoplasmosis vary depending on the age and health of the individual. Healthy adults may experience little to no symptoms, or in some cases a mild flu-like illness. For individuals with weakened immune systems, such as those with HIV or AIDS, the symptoms can be more severe and include:

  • Fever
  • Headache
  • Fatigue
  • Swollen lymph nodes
  • Sore throat
  • Skin rash

In some rare cases, individuals with toxoplasmosis may experience hearing loss, mental confusion, blindness or seizures.

Is Toxoplasmosis Dangerous?

Though it can be dangerous, especially for individuals with weakened immune systems or pregnant women, in most cases, toxoplasmosis can be treated with antibiotics. Toxoplasmosis in pregnant women can cause birth defects in their unborn babies and may pose a significant health risk.

It is also important to practice basic hygiene habits such as washing hands thoroughly after contact with cats or contaminated soil, avoid eating undercooked or raw meat, and wash fruits and vegetables thoroughly before eating.


Knowledge is the best way to protect yourself and your loved ones from toxoplasmosis. It is important to understand the causes, symptoms, and potential health risks associated with this parasite. With proper prevention and hygiene habits, you can reduce your risk of infection.
