What You Need To Know About Infectious Disease

What do you know about infectious disease?

Roughly how many microbes live in the human gastrointestinal tract?

  • Sorry, that’s incorrect.

    About ten trillion microbes live in the human gastrointestinal tract. They are essential for proper digestion and absorption of nutrients.

How long did it take the 2009 “swine flu” pandemic to spread to 30 countries?

  • Sorry, that’s incorrect.

    The 2009 “swine flu” pandemic starkly illustrated the impact of globalization and air travel on the movement of infectious diseases—with the infection spreading to 30 countries within six weeks and to more than 190 countries and territories within months.

  • Correct!

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.

  • Sorry, that’s incorrect.

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.

  • Sorry, that’s incorrect.

For each child who dies from pneumonia in an industrialized country, about how many children die from the infection in developing countries?

  • Sorry, that’s incorrect.

    Life-saving vaccines and medications aren’t distributed equitably around the world; for each child who dies from pneumonia in an industrialized country, more than 2,000 children die from the infection in developing countries.

  • Sorry, that’s incorrect.

Which are examples of ways that pathogens (disease-causing microbes) can spread?

  • 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.

  • Sorry, that’s incorrect.

True or False: Washing your hands with soaps that have residue-producing antibacterial products, such as those containing the chemical triclosan, have been proven to confer health benefits.

  • Sorry, that’s incorrect.

    Washing with regular soap is considered the most important way to prevent disease transmission. Routine consumer use of residue-producing antibacterial products has no added benefit and may actually contribute to antibiotic resistance.

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.
