Toxoplasmosis is a common disease found in birds and mammals across North America.
The infection is caused by a parasite called toxoplasma gondi and affects 10 to 20 out of every 100 people in North America by the time they are adults. Most people who are infected do not show any signs of the disease. Those who do get sick usually have a flu-like illness and may experience fever, sore throat, sore muscles and tiredness. Glands in the neck, armpits or groin can become swollen, but are usually not sore. In some cases the infection can also cause temporary blurred vision or loss of vision.
