What do you know about infectious disease?

How many people in the United States die from flu-related complications each year?

  • Sorry, that’s incorrect.

    About 36,000 people die from flu-related complications each year in the United States. More than 200,000 are hospitalized.

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.

Which reproduce the fastest:

  • Sorry, that’s incorrect.

    Viruses reproduce the fastest. Humans produce a new generation every 20 years or so; bacteria do it every 20 to 30 minutes, and viruses even faster.

  • Sorry, that’s incorrect.

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.

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.

True or False: Not all microbes are harmful to humans.

  • Correct!

    Not all microbes are harmful to humans. In fact, many of them protect us, helping our bodies function properly and competing with harmful organisms in an eternal contest for habitable space in or on our bodies. Although the microorganisms that cause disease often receive more attention, most microorganisms do not cause illness.

Which deadly pathogen cannot be found naturally in the wild:

  • Sorry, that’s incorrect.

    Smallpox cannot be found naturally in the wild. Smallpox was officially declared eradicated from the globe in 1980, after an 11-year WHO vaccination campaign—the first human disease to be eliminated as a naturally spread contagion. Today, the virus remains only in laboratory stockpiles.

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.

Of the more than 1,700 known viruses, bacteria, and other pathogens that infect people, how many have come from animals?

 

 

 

  • Sorry, that’s incorrect.

    More than half of the known pathogens that infect people have come from animals. Of the 37 new infectious diseases identified in just the past 30 years, two-thirds sprang from animals.
