SHS2 Biomedical Science · Semester 2 Week 4: Diseases and Disorders

Lesson notes

Learning Objectives

Indicator: 2.2.2.LI.5 - Discuss the global and social impact of an infectious disease that is caused by bacteria and viruses

By the end of the lesson, learners can:

Identify at least three infectious diseases caused by bacteria and three caused by viruses, stating their mode of transmission for each.
Describe the global impact of a named infectious disease, including statistics on spread, mortality, and economic cost, using at least two specific examples such as COVID-19 or tuberculosis.
Explain the social consequences of infectious diseases on families, communities, and national development, referencing stigma, school closures, and loss of livelihoods.
Compare the societal responses to a bacterial outbreak (such as cholera or tuberculosis) and a viral outbreak (such as COVID-19), noting similarities and differences in control measures.
Create a simple public health poster or message that communicates prevention strategies for a chosen infectious disease to peers, evaluating its potential effectiveness.
