True or False: The only way public health agencies can deal with infectious disease is to have good surveillance in place, wait for an outbreak to happen in a human population, and then rush to contain it.
-
Sorry, that’s incorrect.
By identifying pathogens in the animals where they naturally live and monitoring those organisms as they move from animals into people, it may be possible to prevent deadly new infections of animal origin from entering and racing through human populations.

True or False: Infection with a pathogen (a disease-causing microbe) does not necessarily lead to disease.
-
Correct!
Infection occurs when viruses, bacteria, or other microbes enter your body and begin to multiply. Disease follows when the cells in your body are damaged as a result of infection, and signs and symptoms of an illness appear.

How long did it take the 2009 “swine flu” pandemic to spread to 30 countries?
-
Sorry, that’s incorrect.
The 2009 “swine flu” pandemic starkly illustrated the impact of globalization and air travel on the movement of infectious diseases—with the infection spreading to 30 countries within six weeks and to more than 190 countries and territories within months.

True or False: Thimerosal, a mercury-containing preservative that was used in some vaccines and other products, has been shown to present a risk to human health.
-
Sorry, that’s incorrect.
The use of thimerosal has been an object of controversy, with some arguing that the substance caused autism in children. However, extensive independent research has presented no convincing evidence of harm associated with the low levels of thimerosal previously present in vaccines.
-

True or False: Washing your hands with soaps that have residue-producing antibacterial products, such as those containing the chemical triclosan, have been proven to confer health benefits.
-
Sorry, that’s incorrect.
Washing with regular soap is considered the most important way to prevent disease transmission. Routine consumer use of residue-producing antibacterial products has no added benefit and may actually contribute to antibiotic resistance.

Which of the following diseases kills more children worldwide than any other infectious disease?
- Lower respiratory tract infections (including pneumonia)
- HIV/AIDS
- Diarrheal diseases

Of the more than 1,700 known viruses, bacteria, and other pathogens that infect people, how many have come from animals?
-
Sorry, that’s incorrect.
More than half of the known pathogens that infect people have come from animals. Of the 37 new infectious diseases identified in just the past 30 years, two-thirds sprang from animals.
