12GTHBY1 - Infectious Disease: Home

This unit explores the causes and spread of disease and how humans respond to invading pathogens. Disease is caused by various pathogens that are transmitted between individuals and populations in many different ways.


Infectious diseases are caused by pathogenic microorganisms, such as bacteria, viruses, parasites or fungi; the diseases can be spread, directly or indirectly, from one person to another. Zoonotic diseases are infectious diseases of animals that can cause disease when transmitted to humans.

Infectious Disease:

A pathological condition spread among all biological species. Infectious diseases, although varied in their effects, are always associated with viruses, bacteria, fungi, protozoa, multicellular parasites and aberrant proteins known as prions. A complex series of steps, mediated by factors contributed by both the infectious agent and the host, is required for microorganisms or prions to establish an infection or disease. Worldwide, infectious diseases are the third leading cause of human death.

Communicable disease guidelines:

Strategies to prevent transmission of infection:

** Hand washing with soap and water for at least 15 seconds before preparing or eating food, after using the toilet, changing nappies, after blowing your nose with a tissue and after any contamination of the hands with body fluids such as blood and vomit.

** Effective cleaning with detergent and water, followed by rinsing and drying will remove the bulk of germs from environmental surfaces (refer to your school/day care policy or Staying Healthy in Childcare).

** Use of appropriate cleaning tools and use of protective personal equipment (gloves, masks) is important and should be easily accessible to clean up spills immediately, to prevent aerosol spread of viruses and bacteria.

4 reasons disease outbreaks are erupting around the world: 

Over the past decade, the World Health Organization has declared four global health emergencies. Two of them were in the past two years: the Ebola epidemic in West Africa and the Zika outbreak that's spread through the Americas.

Many of the pathogens that spark deadly outbreaks aren't new. Researchers have known about Zika since the 1940s and Ebola since the 1970s. Some of these viruses have evolved with humans for hundreds or thousands of years.

But viruses, bacteria, and fungi can now spread around the world with greater effectiveness and speed than ever before. And when they turn up unexpectedly in new places, they catch doctors and health systems — and people's immune systems — off guard.

This article introduces four key reasons why we're seeing an uptick in infectious diseases around the world.
