Health, disease and immunity

What makes people ill, how the body fights back, and how medicines and clean habits help.

Sort diseases into those that pass from person to person and those that do not, and meet the four kinds of germ. Follow how germs spread and how clean water, soap and nets stop them. See how the body defends itself, how vaccines train it, and how antibiotics and new medicines work and are tested. Then look at malaria, HIV and tuberculosis, at the habits that raise the risk of heart disease, and at sexual health.

For parents and teachers

For learners who can follow a written argument and have met the body and living things in earlier books. In many schools this fits learners of about 14 to 16, and older learners can use it as a reference. Each chapter takes two or three short sessions. A learner can work alone: every exercise has its answer and the reason for it. The book states established medical science plainly, as a school textbook does. It names no dose, no brand and no medicine for a reader to take, and it never offers a home cure. Where it says that someone may be ill, it says to see a health worker. Each chapter has a Try it made from household things: paper and a pencil for sorting, flour on hands and on oiled card, dry beans, food rubbed on paper, and a walk round the home with an adult to look for standing water. An adult should be near. Beans stay away from small children, nothing is tasted, and no nuts are used. The last chapter, on sexual health, uses the correct names for the parts of the body and says in every section how to stay safe, that nobody may touch you without your yes, and to tell an adult you trust or a health worker when something is wrong.
