Toxoplasmosis is an infection caused by a single-celled parasite called Toxoplasma gondii. The infection is most commonly acquired from contact with cats and their feces or with raw or undercooked meat. Toxoplasmosis does not usually cause any symptoms and in most cases a person does not realise they have caught the infection. It can cause symptoms similar to flu or glandular fever, sometimes including swollen lymph nodes. Once a person has had the disease they are generally thought to be protected for life, unless they suffer an impairment of their immune system.
Outpatient care is sufficient for acquired toxoplasmosis in immunocompetent hosts and for persons with ocular toxoplasmosis. Inpatient care is appropriate initially for persons with CNS toxoplasmosis and for acute toxoplasmosis in immunocompromised hosts.In the Brazil, about 40,610,537 cases of Toxoplasmosis infection are reported in humans each year. Almost 18% of the Brazil population is infected with Toxoplasmosis, a parasite of dogs and cats that can be passed from animals to humans.
