What You Need To Know About Infectious Disease

 

New infectious diseases are emerging and old ones are appearing in new places around the globe. What’s behind this trend? And to what extent has human behavior amplified the problem? The National Academies, advisers to the nation in science, engineering, and medicine, provide the information you need to understand this complex topic.

 

Infection

Microbes are all around us. Most don’t do any harm but what about the few that cause infection? Learn the basics.

Threats

Certain aspects of disease are a particular threat to us today. What are some of the things we're most concerned about in the United States?

Challenges

Infectious disease isn’t limited by national borders. Learn how our modern way of life contributes to the spread and emergence of disease.

What do you know about infectious disease?

Which are examples of ways that pathogens (disease-causing microbes) can spread?

  • Sorry, that’s incorrect.

    All are examples of ways that pathogens can spread. Coughing is an example of airborne droplet transmission; eating undercooked pork is an example of common vehicle transmission; a flea bite is an example of vector transmission; and breathing contaminated dust particles is an example of airborne transmission.

SARS

Severe acute respiratory syndrome (SARS) is a viral respiratory illness. Because it spreads fairly easily, possibly even through the air, SARS was difficult to stop during the 2003 global outbreak.
