What do you know about infectious disease?

For which of the following diseases do we currently lack an effective vaccine for prevention?

  • Sorry, that’s incorrect.

    Although there are treatments available in the form of antivirals, we still currently lack a vaccine for HIV.

  • 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.

  • Correct!

Where do microbes live?

  • Sorry, that’s incorrect.

    Microbes live in all of these places. They also live in plants and in the air. They can even survive in extreme environments like hot springs, deep ocean thermal vents, and polar ice.

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.

  • Correct!

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.

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.
