Quick answer
What is Toxoplasmosis?
Toxoplasmosis is an infection caused by a common parasite (Toxoplasma gondii), caught from eating undercooked or cured meat, from contact with cat faeces (for example when gardening or handling cat litter), or from contaminated food or water. In most healthy people it causes no symptoms or only a mild, flu-like illness with swollen glands, and the immune system controls it, after which it usually causes no further problems.
- How it is treated: Most healthy people with toxoplasmosis need no treatment, as the infection settles on its own.
- Self-care: Cook meat thoroughly, wash fruit and vegetables, wash hands and utensils after handling raw meat, wear gloves when gardening or changing cat litter (and wash hands after), and avoid unpasteurised products.
- When to seek help: See a GP if you are pregnant and think you may have been exposed to toxoplasmosis, or if you have a weakened immune system and become unwell.
What it is
Toxoplasmosis is an infection caused by a common parasite (Toxoplasma gondii), caught from eating undercooked or cured meat, from contact with cat faeces (for example when gardening or handling cat litter), or from contaminated food or water. In most healthy people it causes no symptoms or only a mild, flu-like illness with swollen glands, and the immune system controls it, after which it usually causes no further problems. It becomes important in two groups: pregnant women, because a first infection during pregnancy can occasionally be passed to the baby and cause harm; and people with weakened immune systems (such as some cancer treatments or advanced HIV), in whom it can reactivate and cause serious illness. Diagnosis is by blood tests, and sometimes other tests depending on the situation.
How it is treated
Most healthy people with toxoplasmosis need no treatment, as the infection settles on its own. Treatment with specific medicines is used when needed — for example in people with weakened immunity, in some cases during pregnancy to reduce the risk to the baby, or when it affects the eyes or other organs. In pregnancy, if infection is suspected, specialist advice guides testing, treatment and monitoring of the baby. Prevention is the most useful message for everyone, and especially for pregnant women and those with weakened immunity: cooking meat thoroughly, washing fruit and vegetables, good hand and kitchen hygiene, and taking care with cat litter and gardening (wearing gloves and washing hands).

Lifestyle and self-care
Cook meat thoroughly, wash fruit and vegetables, wash hands and utensils after handling raw meat, wear gloves when gardening or changing cat litter (and wash hands after), and avoid unpasteurised products. These precautions especially matter in pregnancy and with weakened immunity.
When to get help
When to see a doctor
See a GP if you are pregnant and think you may have been exposed to toxoplasmosis, or if you have a weakened immune system and become unwell. Seek advice for persistent swollen glands with a flu-like illness.

Answers
Toxoplasmosis: frequently asked questions
Is toxoplasmosis dangerous?
In most healthy people it is mild or causes no symptoms. It is important in pregnancy (a first infection can occasionally harm the baby) and in people with weakened immune systems, in whom it can cause serious illness.
Can I catch toxoplasmosis from my cat?
It can be caught from contact with cat faeces (for example handling litter or gardening), as well as from undercooked meat and unwashed produce. Good hygiene and precautions — especially in pregnancy — reduce the risk.
