True or False: The only way public health agencies can deal with infectious disease is to have good surveillance in place, wait for an outbreak to happen in a human population, and then rush to contain it.

  • Sorry, that’s incorrect.

    By identifying pathogens in the animals where they naturally live and monitoring those organisms as they move from animals into people, it may be possible to prevent deadly new infections of animal origin from entering and racing through human populations.

  • Correct!

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.

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.

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.
