What You Need To Know About Infectious Disease

What do you know about infectious disease?

“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.

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.

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.

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!

How many people in the world do not have access to an adequate water supply?

  • Sorry, that’s incorrect.

    Worldwide, 884 million people do not have access to an adequate water supply, and about three times that number lack basic sanitation services. An estimated 2 million deaths a year can be attributed to unsafe water supplies.

True or False: Major pharmaceutical companies have great interest in dedicating resources to the antibiotics market because these short-course drugs are more profitable than drugs that treat chronic conditions and lifestyle ailments, such as high blood pressure or high cholesterol.

  • Sorry, that’s incorrect.

    Drugs that treat chronic conditions and lifestyle ailments are more profitable. Modern medicine needs new kinds of antibiotics to treat drug-resistant infections, but antibiotic research and development are expensive, risky, and time-consuming.

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.

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.
