What should you know about DDT polio?

The term “DDT polio” is not a standard medical name for a separate type of polio. If you saw these words on a document, message, or result, show the exact wording to a clinician so it can be clarified in context.

Poliovirus can pass between people, particularly when hygiene and sanitation are poor. Some infections cause no noticeable symptoms. Others may cause fever, tiredness, headache, nausea, stomach upset, or pain in the limbs. In a small proportion of infections, the virus affects nerves and can cause muscle weakness or paralysis.

Paralysis can interfere with movement or breathing and needs urgent medical care. A person can spread the virus even when they do not look unwell, which is why community vaccination protects people who may not yet have been exposed.

Check whether the child or adult has received the recommended polio-containing vaccines, and take the vaccination record to a healthcare professional if it is incomplete or unclear. A clinician can advise on catch-up doses and on protection after travel or contact with an affected person.

Wash hands carefully after using the toilet and before preparing or eating food. Do not share food, drinks, or personal items with someone who may have an infectious illness. For routine vaccine advice, read about [Childhood Immunisation](/treatments/preventive-care-and-vaccination/childhood-immunisation/).

Seek urgent medical help for new muscle weakness, inability to move an arm or leg, difficulty swallowing, trouble speaking, or breathing difficulty, especially after fever or an illness. These symptoms can have causes other than polio, but they should not be watched at home.

Arrange medical advice for fever with marked weakness, persistent vomiting, severe headache, or possible exposure to polio. Tell the service about recent travel, vaccination history, and contact with anyone diagnosed with the infection.

Ask which polio vaccines are recorded, whether any doses are due, and whether a recent exposure or planned travel changes the advice. If “DDT polio” appears in your paperwork, ask what the abbreviation refers to and whether it describes a diagnosis, a test, or an administrative note.
