Which is the vector (animal that carries the pathogen) for West Nile virus?

  • Sorry, that’s incorrect.

    The mosquito is the vector for West Nile virus. The mosquito suffers no ill effects from the virus but transmits it to humans and other warm-blooded creatures (such as crows) when it takes a blood meal. 

  • 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.

About how often is someone in the world newly infected with tuberculosis (TB)?

  • Correct!

    Someone in the world is newly infected with tuberculosis (TB) every second. In 2008 there were an estimated 9.4 million new cases of tuberculosis and 1.8 million deaths.The vast majority of TB deaths are in the developing world, and more than half of all deaths occur in Asia.

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.

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.
