What You Need To Know About Infectious Disease
What do you know about 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.

True or False: If you have a cold or the flu, taking antibiotics will help treat the infection.
-
Sorry, that’s incorrect.
Antibiotics only work on bacterial infections, not viral infections such as influenza and the common cold. In fact, inappropriate use and overuse of antibiotics contributes to the emergence of drug-resistant bacteria.

True or False: Most infectious diseases are not impacted by changes in the environment.
-
Sorry, that’s incorrect.
Most infectious diseases are impacted by changes in the environment. Malaria, dengue, and viral encephalitis infections, for example, are highly sensitive to environmental changes.

The human papillomavirus (HPV) causes about what percentage of cervical cancer cases?
-
Sorry, that’s incorrect.
The human papillomavirus (HPV) causes more than 90% of cervical cancer cases.

Which of the following is a bacterial infection?
-
Sorry, that’s incorrect.
Strep throat is a bacterial infection. Hookworm is caused by a parasite and chickenpox and influenza are both caused by viruses.

True or False: Scientists predict that rising average temperatures in some regions will change the transmission dynamics and geographic range of cholera, malaria, dengue fever, and tick-borne diseases.
-
Correct!
Scientists predict that rising average temperatures in some regions—a result of climate change—will change the transmission dynamics and geographic range of cholera, malaria, dengue fever, and tick-borne diseases.

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.

-
Sorry, that’s incorrect.
Since the beginning of the 20th century the number of people in the world has more than quadrupled—from 1.6 billion to nearly 7 billion—and world population is expected to rise to well over 9 billion by 2050.

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
- Bacteria
A large group of unicellular microorganisms that lack a cell nucleus. Some bacteria are pathogenic and harmful to humans, some have no effect at all on humans, and some are beneficial.
