What You Need To Know About Infectious Disease
What do you know about infectious disease?
How long did it take the 2009 “swine flu” pandemic to spread to 30 countries?
-
Sorry, that’s incorrect.
The 2009 “swine flu” pandemic starkly illustrated the impact of globalization and air travel on the movement of infectious diseases—with the infection spreading to 30 countries within six weeks and to more than 190 countries and territories within months.

About how often is someone in the world newly infected with tuberculosis (TB)?
-
Correct!
Someone in the world is newly infected with tuberculosis (TB) every second. In 2008 there were an estimated 9.4 million new cases of tuberculosis and 1.8 million deaths.The vast majority of TB deaths are in the developing world, and more than half of all deaths occur in Asia.

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: Infection with a pathogen (a disease-causing microbe) does not necessarily lead to disease.
-
Correct!
Infection occurs when viruses, bacteria, or other microbes enter your body and begin to multiply. Disease follows when the cells in your body are damaged as a result of infection, and signs and symptoms of an illness appear.

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: 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.

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.

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.
