Which of the following global events does NOT have an impact on the spread of infectious disease:
-
Sorry, that’s incorrect.
The expanded use of cell phones does not have an impact on the spread of infectious disease. Climate change, ecosystem disturbances, war, poverty, migration, and global trade all contribute to the spread of infectious disease.

Which of the following is NOT a type of infectious agent?
-
Sorry, that’s incorrect.
White blood cells are not a type of infectious agent. Part of the immune system, white blood cells fight infection rather than cause it.

“Antibiotic resistance” refers to:
- The reluctance of physicians to prescribe antibiotics
- An underground movement against pharmaceutical companies
- The ability of bacteria to resist the effects of an antibiotic
-
Sorry, that’s incorrect.
“Antibiotic resistance” refers to the ability of bacteria to resist the effects of an antibiotic. Antibiotic resistance occurs when bacteria undergo a genetic change that reduces or eliminates the effectiveness of drugs or other agents designed to cure or prevent infection.

About how much of its fish and seafood does the United States import?
-
Sorry, that’s incorrect.
The United States imports more than 80 percent of its fish and seafood. About 20 percent of its fresh vegetables and 50 percent of its fresh fruits are imported. As wealthy nations demand such foods year-round, the increasing reliance on producers abroad means that food may be contaminated during harvesting, storage, processing, and transport—long before it reaches overseas markets.

In 2008, about how many people worldwide were infected with HIV (human immunodeficiency virus)?
-
Sorry, that’s incorrect.
In 2008, more than 33 million people worldwide were infected with HIV (human immunodeficiency virus). In that same year, an estimated 2 million people died from AIDS (acquired immunodeficiency syndrome), the final stage of HIV infection.

Which are examples of ways that pathogens (disease-causing microbes) can spread?
- Coughing
- Eating undercooked pork
- Flea bite
- Breathing dust particles containing microorganisms
- All of the above
-
Sorry, that’s incorrect.
All are examples of ways that pathogens can spread. Coughing is an example of airborne droplet transmission; eating undercooked pork is an example of common vehicle transmission; a flea bite is an example of vector transmission; and breathing contaminated dust particles is an example of airborne transmission.

How many people in the world do not have access to an adequate water supply?

Sorry, that’s incorrect.
Worldwide, 884 million people do not have access to an adequate water supply, and about three times that number lack basic sanitation services. An estimated 2 million deaths a year can be attributed to unsafe water supplies.

About what percentage of the antibiotics produced in the United States is added to animal feeds to promote growth?
-
Sorry, that’s incorrect.
Almost 70% of all the antibiotics produced in the United States is added to animal feeds—not to fend off disease but to boost growth. These non-therapeutic uses of antibiotics are a perfect way to cultivate microbes that are resistant to antibiotics.
