Who started the prevention of illness?
The modern era in preventive medicine opened in the mid-19th century with Louis Pasteur’s discovery of the role of living microbes as the cause of infections. Toward the close of the century the principle of insect-borne transmission of disease was established.
What was the cause of leprosy?
Hansen’s disease (also known as leprosy) is an infection caused by slow-growing bacteria called Mycobacterium leprae. It can affect the nerves, skin, eyes, and lining of the nose (nasal mucosa).
What are the impacts of disease?

How was the plague cured?
Unlike Europe’s disastrous bubonic plague epidemic, the plague is now curable in most cases.

When the second population dies, the fleas move on to other hosts, including people, thus creating a human epidemic.
What are the methods of disease control?
The infectious diseases may be prevented in one of two general ways: (1) by preventing contact, and therefore transmission of infection, between the susceptible host and the source of infection and (2) by rendering the host unsusceptible, either by selective breeding or by induction of an effective artificial immunity.
