The effect of antigen variability on disease and disease prevention. 0.2 weeks Explain that antigen variability can lead to some diseases being caught more than once. Explain how mutations can cause antigen variability and how this can cause new strains of pathogen. Explain the consequences of antigen variability on the incidence of disease and the development of therapies against that disease. Learning activities: teacher led introduction to antigenic variability through gene mutation students examine information about past epidemics/ pandemics eg influenza outbreaks over the last century and why periodically some are so serious students could research the modern focus on disease prevention using internet materials and why recent outbreaks eg avian and swine flu, have attracted such media focus teacher summary could bring together their findings and discuss the consequences of antigen variability of disease prevention and treatments. Skills developed by learning activities: MS 0.3 – calculate and understand the use of percentages or values per Exampro: BYB7 June 2004 Q6 HBIO1 – June 2012 Q2 Rich questions: Suggest why we can suffer from some diseases multiple times, but we get others only once and are then immune. Why is it so difficult to develop a vaccine against the common cold or HIV? Why have many animal flu viruses eg bird flu, made the news so often in recent years? During recent flu outbreaks, the government invested in Tamiflu to protect the population in the event of a
