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

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 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.

If you have strep throat, which of the following forms of medication can be used to effectively treat the infection?
-
Sorry, that’s incorrect.
Because strep throat is caused by a bacterium called Streptococcus pyogenes, it is treatable with antibiotics but not antivirals. Currently there is no vaccine available to prevent strep throat.

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.

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.
