Your veterinarian may discover changes in your cat's health that you have overlooked. It is always better to err on the side of caution. In humans, it may affect many different organs of the body, causing many different types of clinical signs. The respiratory system is commonly involved and pneumonia may result. The most common finding is a mild, flu-like illness that lasts a few days.
Most people recover uneventfully.
Even if the patient sees a physician, the illness may still be attributed to the flu unless special blood tests are run. If a pregnant woman contracts toxoplasmosis, it is possible for the toxo organism to affect the unborn baby. It is this form of the disease that has the most dire consequences because the baby may be affected for life. Exposure to the toxo organism will result in the production of antibodies. Antibodies are the defense agents of the immune system and are produced in response to immune system stimulation.
