According to George Armelagos, author of The Viral Superhighway, new pathogens such as Ebola are unlikely to cause a widespread epidemic. Why? 1. Because the Ebola virus sickens and kills its hosts, whereby victims can easily be identified and isolated from others in the population. 2. Because there is a cure for the Ebola virus. 3. Because the Ebola virus is restricted to isolated human populations and thus can be controlled and swiftly eradicated before it spreads into other human populations. 4. All of the above. 5. None of the above.

Outbreaks of infectious diseases such as the Ebola virus make news headlines and generate a lot of fear. However, when compared to the flu virus or HIV, a disease such as Ebola is less likely to cause as many infections (see figure below). What characteristics of the diseases contribute to this difference? How do some cultural practices facilitate the spread of viruses? The number of people that one sick person will infect (on average) is called R. Here are the maximum Ro values for a few viruses: more contagious Ro Hepatitis C (2), Ebola (2), HIV (4), Mumps (10), Measles (18).

Ebola is a dangerous and often lethal viral disease spread from person to person through direct contact with blood or body secretions. The largest outbreak of Ebola began in West Africa in $2014 .$ Many healthcare workers from the United States and Europe traveled to West Africa to help treat Ebola patients in that region. One health-care worker, Kaci Hickox, returned to the United States and was told she was to be isolated, or quarantined, in a tent behind a hospital in New Jersey. She protested the precautionary quarantine and was released early. Ebola experts note that an infected person can only transmit the virus when they are showing symptoms of the disease. How long does a person exposed to Ebola need to be quarantined to be declared disease-free? Should health-care workers exposed to Ebola who are not showing symptoms be forced into quarantine? Answer this last question from the perspective of a doctor and then again from the viewpoint of a government official.
To cause a human pandemic, the H5N1 avian flu virus would have to a. spread to primates such as chimpanzees. b. develop into a virus with a different host range. c. become capable of human-to-human transmission. d. become much more pathogenic.
