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

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.

Which deadly pathogen cannot be found naturally in the wild:
-
Sorry, that’s incorrect.
Smallpox cannot be found naturally in the wild. Smallpox was officially declared eradicated from the globe in 1980, after an 11-year WHO vaccination campaign—the first human disease to be eliminated as a naturally spread contagion. Today, the virus remains only in laboratory stockpiles.

“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.
