Toxaemia is a medical condition in which poisons are present in the blood and spread around the body, making a person seriously ill. It usually happens because bacteria growing somewhere — in a wound, in the gut, in an infected tooth — release poisons that get into the bloodstream. The word is spelled toxaemia in British English and toxemia in American English; the sound is the same. It is a doctor's word, not an everyday one, and here is the honest part: modern doctors mostly do not use it any more. What older books called toxaemia is now usually called sepsis or septicaemia, and those are the words a hospital would use today. You will still meet toxaemia in one place, though — 'toxaemia of pregnancy', an older name for the dangerous condition of high blood pressure in a pregnant woman, which doctors now call pre-eclampsia. So treat this word as one you should be able to read rather than one you need to say. If you meet it in an old novel or an old medical text, it means blood poisoning.
