Discuss the challenges for prevention and control of a particular infectious disease. Some things you may consider as you discuss this topic: Does this disease already have a vaccination, and if so, is the challenge in getting people to get vaccinated, or in creating a vaccine, or something else? How does the biology of a virus (for example, influenza or HIV) or bacteria (for example, TB or MRSA) present a challenge for its control? How can/do some organisms cause pandemics and how are different species (humans, animals) involved in that process? What do you think may be the next infectious disease pandemic, and why? What organisms do you think are most at risk for bioterrorism use, and why? What efforts are in place to prevent infectious disease related bioterrorism, and are they sufficient?
