What You Need To Know About Infectious Disease

What do you know about infectious disease?

Which of the following is a bacterial infection?

  • Sorry, that’s incorrect.

    Strep throat is a bacterial infection. Hookworm is caused by a parasite and chickenpox and influenza are both caused by viruses.

  • Sorry, that’s incorrect.

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.

  • 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.

  • Correct!

True or False: Antibiotics work by introducing an agent that resembles a disease-causing microbe, thus stimulating the body's immune system to recognize it as foreign, destroy it, and "remember" it, so that it can more easily identify and destroy any similar, disease-causing microbes that it later encounters.

  • Sorry, that’s incorrect.

    The above describes how vaccines work. Antibiotics work by either killing bacteria or stopping them from reproducing, allowing the body's natural defenses to eliminate the pathogens.

  • Correct!

True or False: Scientists believe that hot weather may speed up both the breeding cycle of mosquitoes and replication of the virus in insects’ guts.

  • Correct!

    Scientists believe that hot weather may speed up both the breeding cycle of mosquitoes and replication of the virus in insects’ guts.

  • Sorry, that’s incorrect.

Public health officials can identify the outbreak of disease by monitoring certain patterns of behavior through syndromic surveillance. Which of the following is one of the signs used to identify a disease outbreak using this system?

  • Sorry, that’s incorrect.

    In syndromic surveillance, all of the above are used in addition to other patterns that suggest an outbreak. Despite the emergence of this innovative surveillance method, most surveillance still depends on tracking reported infections.

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.

Which of the following is not a viral disease:

  • Sorry, that’s incorrect.

    Trichinosis is not a viral disease. It is caused by a helminth (parasitic worm) found in undercooked meat, not by a virus. 

  • Sorry, that’s incorrect.

    Trichinosis is not a viral disease. It is caused by a helminth (parasitic worm) found in undercooked meat, not by a virus.

Each year, how many Americans become infected by what they eat?

  • Sorry, that’s incorrect.

    Each year about 76 million Americans—or one in four—become infected by what they eat. Approximately 325,000 are hospitalized. More than 5,000 (14 a day) die.
