True or False: Major pharmaceutical companies have great interest in dedicating resources to the antibiotics market because these short-course drugs are more profitable than drugs that treat chronic conditions and lifestyle ailments, such as high blood pressure or high cholesterol.

  • Sorry, that’s incorrect.

    Drugs that treat chronic conditions and lifestyle ailments are more profitable. Modern medicine needs new kinds of antibiotics to treat drug-resistant infections, but antibiotic research and development are expensive, risky, and time-consuming.

  • Correct!

Public health officials can identify the outbreak of disease by monitoring certain patterns of behavior through syndromic surveillance. Which of the following is one of the signs used to identify a disease outbreak using this system?

  • Sorry, that’s incorrect.

    In syndromic surveillance, all of the above are used in addition to other patterns that suggest an outbreak. Despite the emergence of this innovative surveillance method, most surveillance still depends on tracking reported infections. 

  • Sorry, that’s incorrect.

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.

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.
