Bevezetés

Some microbes can be harmful to humans and can cause disease: the Influenza virus causes the flu, Campylobacter bacteria can cause food poisoning, and dermatophyte fungi, such as Trichophyton, can cause diseases such as athlete’s foot and ringworm. Microbes like these are known as pathogens. Each pathogenic microbe can make us ill in different ways.

Someone who is ill because of a harmful disease-causing microbe is said to be infected. Many harmful microbes can pass from one person to another by a number of different routes – air, touch, water, food, aerosols (such as sneezes and water vapour), animals, etc... Diseases caused by such microbes are said to be infectious diseases.

In this lesson plan, students discover the different types of infectious diseases caused by harmful microbes and their characteristics. They explore how infectious diseases can spread and consider how they would manage an outbreak.
