What You Need To Know About Infectious Disease

What do you know about infectious disease?

About how many airline passengers cross international borders daily?

  • Sorry, that’s incorrect.

    An estimated 1.8 million airline passengers cross international borders daily, creating routes by which human infections can radiate around the world within hours.

  • Sorry, that’s incorrect.

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.

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.

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.

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.

Which of the following diseases kills more children worldwide than any other infectious disease?

  • Correct!

    Lower respiratory tract infections (including pneumonia) kill more children worldwide than any other infectious disease. Together these diseases are the five leading causes of infectious disease worldwide, accounting for nearly one-fifth of all deaths.

For each child who dies from pneumonia in an industrialized country, about how many children die from the infection in developing countries?

  • Sorry, that’s incorrect.

    Life-saving vaccines and medications aren’t distributed equitably around the world; for each child who dies from pneumonia in an industrialized country, more than 2,000 children die from the infection in developing countries.

True or False: Infection with a pathogen (a disease-causing microbe) does not necessarily lead to disease.

  • Correct!

    Infection occurs when viruses, bacteria, or other microbes enter your body and begin to multiply. Disease follows when the cells in your body are damaged as a result of infection, and signs and symptoms of an illness appear.

  • 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.
