What You Need To Know About Infectious Disease

What do you know about infectious disease?

Which of the following is NOT a vector-borne disease?

  • Correct!

    Influenza is not a vector-borne disease, meaning it is not transmitted to humans indirectly via an insect, an arthropod, or another animal. Malaria and yellow fever are transmitted by mosquitoes. Lyme disease is transmitted by deer ticks.

  • Sorry, that’s incorrect.

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.

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.

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.

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.

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.

True or False: Our bodies contain at least 10 times more human cells than bacterial cells.

  • Sorry, that’s incorrect.

    Our bodies contain at least 10 times more bacterial cells than human cells. 

  • Correct!

    Our bodies contain at least 10 times more bacterial cells than human cells. 

True or False: Growing evidence suggests that infections are behind many chronic diseases once thought to be caused by genetic, environmental, or lifestyle factors.

  • Correct!
    Growing evidence does suggest that infections are behind many chronic diseases once thought to be caused by genetic, environmental, or lifestyle factors, including peptic ulcers and cervical, liver, and gastric cancers.
  • Sorry, that’s incorrect.

Which of the following is needed to help improve the public health situation in developing countries?

  • Sorry, that’s incorrect.

    All of the above are urgently needed in developing nations. A major barrier to achieving these improvements is the underlying weakness of health systems in resource-poor countries, including a shortage of health workers and a lack of disease surveillance programs.

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.
