This case study centers on an active teaching game that simulates a cholera outbreak among five villages along a river, similar to the Haitian outbreak of 2010. By enacting the behaviors of fictional villagers, students learn how trade, travel, sanitation practices and geographic location contribute to the spread of diarrheal disease. Documenting various contamination events of village water supplies allows students to trace the progression of the disease and illustrates how adequate sanitation facilities provide protection against the bacteria Vibrio cholera. Originally designed for an undergraduate upper-division biology course focusing on the epidemiology of diseases, the simulation is also appropriate for microbiology and public health courses, as well as lower division undergraduate biology courses and high school. Biology or epidemiology components of the case study can be highlighted depending on the emphasis of the course being taught. The game can be completed within a 45- to 60-minute class period. Playing cards are available from the Supplemental Materials tab; detailed instructions are found in the teaching notes.

TeachUNICEF is a portfolio of free global education resources. Resources cover grades PK-12, are interdisciplinary (social studies, science, math, English/language arts, foreign/world languages), and align with standards. The lesson plans, stories, and multimedia cover topics ranging from the Millennium Development Goals to Water and Sanitation. Our mission is to support and create well-informed global citizens who understand interconnectedness, respect and value diversity, have the ability to challenge injustice and inequities and take action in personally meaningful ways. We hope that in providing engaging and academically rich materials that offer multiple voices, we can encourage the exploration of critical global issues while presenting opportunities to take action.

If you think you can rid your body of bacteria with a quick squirt of hand sanitizer, you'd be oh so wrong. Turns out we have an incredible array of microorganisms living on us AND inside us. But as Anthony tells you, these little guys do some very important work.

Germ theory states that specific microscopic organisms are the cause of specific diseases. The theory was developed, proved, and popularized in Europe and North America between about 1850 and 1920. Because its implications were so different from the centuries-old humoral theory, germ theory revolutionized the theory and practice of medicine and the understanding of disease. It was, however, compatible with existing ideas about health, especially those associated with 19th-century hygiene and sanitation.

Behold the microscopic jungle in and around you: tiny organisms living on your cheeks, under your sofa and in the soil in your backyard. We have an adversarial relationship with these microbes -- we sanitize, exterminate and disinfect them -- but according to microbiologist Anne Madden, they're sources of new technologies and medicines waiting to be discovered. These microscopic alchemists aren't gross, Madden says -- they're the future.
