Assessments in Module 3 include one open response item, two multiple-choice questions and a formative assessment task.
Describe the factors (biological and human behaviors) that my cause an outbreak of a viral disease to develop into an epidemic or not. Use your understandings from the timeline and readings in this module.
- Mode of transmission of virus: direct and indirect contact (Ebola, HIV, measles, smallpox, influenza)
- Diseases that are spread by insect vectors: if the vectors are abundant and are found in close proximity to humans (Zika, Bubonic plague, typhus)
- Human behavior: that result in increases in the density of vectors, such as careless disposal of trash; poor sanitation leading to contaminated water; careless food preparation; burial practices (Zika, Cholera, Salmonella, SARS, Ebola)
The best treatment for an unknown viral disease is
In order to multiply, a virus must
- Conjugate with another virus
- Invade a host cell
- Manufacture extra food
- Remain hidden
Students create a fictitious viral disease with symptoms, causative agent and mode of transmission and present it and have the class decide whether it is contagious or not.
