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

Correct!

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.

What fraction of all deaths worldwide are caused by infectious disease?

Sorry, that’s incorrect.
About one quarter of all deaths worldwide are caused by infectious disease. More than two-thirds of the deaths in children under the age of five are caused by infectious disease.

Which reproduce the fastest:
-
Sorry, that’s incorrect.
Viruses reproduce the fastest. Humans produce a new generation every 20 years or so; bacteria do it every 20 to 30 minutes, and viruses even faster.

The human papillomavirus (HPV) causes more than 90% of cervical cancer cases.

The 1918 influenza pandemic (the so-called “Spanish” flu) is estimated to have killed how many people worldwide?
-
Sorry, that’s incorrect.
The 1918 influenza pandemic is estimated to have killed between 50 million and 100 million people worldwide. Many of those deaths were due to the effects of pneumococcal pneumonia, a secondary complication of flu for which no antibiotics existed in 1918.

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.
