What You Need To Know About Infectious Disease

What do you know about infectious disease?

What fraction of all deaths worldwide are caused by infectious disease?

  • Sorry, that’s incorrect.

    About one quarter of all deaths worldwide are caused by infectious disease. More than two-thirds of the deaths in children under the age of five are caused by infectious disease.

  • Correct!

Which of the following is an effective way to protect yourself against infectious disease?

  • Sorry, that’s incorrect.

    All of the above can help prevent infectious disease. Other behaviors, such as exercising caution around wild and unfamiliar domestic animals, avoiding insect bites, practicing safe sex, and being vigilant about disease threats while traveling abroad, can also reduce the risk of infection.

The 1918 influenza pandemic (the so-called “Spanish” flu) is estimated to have killed how many people worldwide?

  • Sorry, that’s incorrect.

    The 1918 influenza pandemic is estimated to have killed between 50 million and 100 million people worldwide. Many of those deaths were due to the effects of pneumococcal pneumonia, a secondary complication of flu for which no antibiotics existed in 1918.

“Antibiotic resistance” refers to:

  • Sorry, that’s incorrect.

    “Antibiotic resistance” refers to the ability of bacteria to resist the effects of an antibiotic. Antibiotic resistance occurs when bacteria undergo a genetic change that reduces or eliminates the effectiveness of drugs or other agents designed to cure or prevent infection.

  • Sorry, that’s incorrect.

True or False: The clearing and settlement of tropical rainforests has exposed woodcutters, farmers, and ecotourists to new vector-borne diseases.

  • 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. 

  • Sorry, that’s incorrect.

Which of the following global events does NOT have an impact on the spread of infectious disease:

  • Sorry, that’s incorrect.

    The expanded use of cell phones does not have an impact on the spread of infectious disease. Climate change, ecosystem disturbances, war, poverty, migration, and global trade all contribute to the spread of infectious disease.

  • Correct!

Where do microbes live?

  • Sorry, that’s incorrect.

    Microbes live in all of these places. They also live in plants and in the air. They can even survive in extreme environments like hot springs, deep ocean thermal vents, and polar ice.

  • 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.
