About how much of its fish and seafood does the United States import?

  • Sorry, that’s incorrect.

    The United States imports more than 80 percent of its fish and seafood. About 20 percent of its fresh vegetables and 50 percent of its fresh fruits are imported. As wealthy nations demand such foods year-round, the increasing reliance on producers abroad means that food may be contaminated during harvesting, storage, processing, and transport—long before it reaches overseas markets.

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.

True or False: If you have a cold or the flu, taking antibiotics will help treat the infection.

  • Sorry, that’s incorrect.

    Antibiotics only work on bacterial infections, not viral infections such as influenza and the common cold. In fact, inappropriate use and overuse of antibiotics contributes to the emergence of drug-resistant bacteria. 

  • Correct!

Which of the following is NOT a type of infectious agent?

  • Sorry, that’s incorrect.

    White blood cells are not a type of infectious agent. Part of the immune system, white blood cells fight infection rather than cause it.

Which of the following is NOT a vector-borne disease?

  • Correct!

    Influenza is not a vector-borne disease, meaning it is not transmitted to humans indirectly via an insect, an arthropod, or another animal. Malaria and yellow fever are transmitted by mosquitoes. Lyme disease is transmitted by deer ticks.

  • Sorry, that’s incorrect.

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.

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.
