Health and disease

When students at a school become sick, it becomes clear a serious outbreak of tuberculosis (TB) is occurring. Can doctors prevent its spread, and can they minimize the harm that is being caused by a rare strain of the disease? This book looks at the topics of health and disease to explain how pathogens, such as bacteria and viruses, can affect our health and pass from person to person. It shows how medical professionals use their knowledge of science and technology to track down those infected by TB and to give them treatment.
