Which of the following is an effective way to protect yourself against infectious disease?
- Keep immunizations up to date
- Wash your hands often
- Prepare and handle food carefully
- All of the above
-
Sorry, that’s incorrect.
All of the above can help prevent infectious disease. Other behaviors, such as exercising caution around wild and unfamiliar domestic animals, avoiding insect bites, practicing safe sex, and being vigilant about disease threats while traveling abroad, can also reduce the risk of infection.

True or False: Antibiotics work by introducing an agent that resembles a disease-causing microbe, thus stimulating the body's immune system to recognize it as foreign, destroy it, and "remember" it, so that it can more easily identify and destroy any similar, disease-causing microbes that it later encounters.
-
Sorry, that’s incorrect.
The above describes how vaccines work. Antibiotics work by either killing bacteria or stopping them from reproducing, allowing the body's natural defenses to eliminate the pathogens.

Which of these viral diseases has the most antiviral drugs available to treat it?
-
Sorry, that’s incorrect.
Today there are more antiviral drugs available for HIV than for any other viral disease, transforming an infection that was once considered a death sentence into a manageable chronic condition.
-
Correct!

True or False: Scientists believe that hot weather may speed up both the breeding cycle of mosquitoes and replication of the virus in insects’ guts.
-
Correct!

Which is the vector (animal that carries the pathogen) for West Nile virus?
-
Sorry, that’s incorrect.
The mosquito is the vector for West Nile virus. The mosquito suffers no ill effects from the virus but transmits it to humans and other warm-blooded creatures (such as crows) when it takes a blood meal.

About how many airline passengers cross international borders daily?
-
Sorry, that’s incorrect.
An estimated 1.8 million airline passengers cross international borders daily, creating routes by which human infections can radiate around the world within hours.

True or False: Major pharmaceutical companies have great interest in dedicating resources to the antibiotics market because these short-course drugs are more profitable than drugs that treat chronic conditions and lifestyle ailments, such as high blood pressure or high cholesterol.
-
Sorry, that’s incorrect.
Drugs that treat chronic conditions and lifestyle ailments are more profitable. Modern medicine needs new kinds of antibiotics to treat drug-resistant infections, but antibiotic research and development are expensive, risky, and time-consuming.

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.

Infectious Disease Defined
- Ecosystem
A functional unit that consists of all the living organisms in a particular area, as well as the nonliving, physical components in the environment—such as air, soil, water, and sunlight—with which the organisms interact, and how natural and human-made changes affect these interactions.
