Which of the following is needed to help improve the public health situation in developing countries?

  • Sorry, that’s incorrect.

    All of the above are urgently needed in developing nations. A major barrier to achieving these improvements is the underlying weakness of health systems in resource-poor countries, including a shortage of health workers and a lack of disease surveillance programs.

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!

Which of the following can be treated with antibiotics?

  • Sorry, that’s incorrect.

    Strep throat is a bacterial infection that can be treated with antibiotics. The common cold and influenza are both viral infections, which do not respond to antibiotics. Antivirals may be prescribed instead.

  • Sorry, that’s incorrect.

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

About what percentage of the antibiotics produced in the United States is added to animal feeds to promote growth?

  • Sorry, that’s incorrect.

    Almost 70% of all the antibiotics produced in the United States is added to animal feeds—not to fend off disease but to boost growth. These non-therapeutic uses of antibiotics are a perfect way to cultivate microbes that are resistant to antibiotics.
