What You Need To Know About Infectious Disease
What do you know about infectious disease?
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.
-
Correct!

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 vector-borne disease?
-
Correct!
Influenza is not a vector-borne disease, meaning it is not transmitted to humans indirectly via an insect, an arthropod, or another animal. Malaria and yellow fever are transmitted by mosquitoes. Lyme disease is transmitted by deer ticks.

True or False: Growing evidence suggests that infections are behind many chronic diseases once thought to be caused by genetic, environmental, or lifestyle factors.
-
Correct!Growing evidence does suggest that infections are behind many chronic diseases once thought to be caused by genetic, environmental, or lifestyle factors, including peptic ulcers and cervical, liver, and gastric cancers.

True or False: Not all microbes are harmful to humans.
-
Correct!
Not all microbes are harmful to humans. In fact, many of them protect us, helping our bodies function properly and competing with harmful organisms in an eternal contest for habitable space in or on our bodies. Although the microorganisms that cause disease often receive more attention, most microorganisms do not cause illness.

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.

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: 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.
