Section	Time
15.17 – Infectious diseases	Approx. 3 lessons

Learning Objectives To recall that pathogens such as bacteria, viruses and fungi cause some diseases. To know that pathogens are transmitted by droplet infection, contact, food or water. To understand that natural immunity is the production of antibodies in response to antigens and that we have immunological memory. To understand that artificial immunity is brought about by vaccination and that the effectivity of vaccination is affected by antigen variability. To recall the herd immunity effect and interpret data on immunisations and epidemics.
