This video illustrates conditions under which two infectious diseases - cholera and dengue fever - flourish, and how climate change is likely to exacerbate those conditions.

The link between climate change and disease is not as well developed in the video as one might like. Recommend using the associated lesson plan on the website to make this connection clearer.
The first half of the video focuses on cholera (bacteria infection from contaminated water) and the second half focuses on dengue fever (virus-based disease spread by mosquitoes).
Climate change is only one of many variables that relate to disease vectors. Learners should be aware of the complexities of diseases to avoid oversimplifying the topic.
Passed initial science review - expert science review pending.
A link to a lesson plan that incorporates this video is provided just below the video screen.
Many of these diseases are difficult to treat or prevent medically, so it is important that we understand how they might be affected by climate change so we can predict and prepare for them.
The music accompanying the video is melodramatic.
Low resolution video may be grainy or pixelated when projected on a large screen.
Advertisements on Windows to the Universe site may be distracting for some learners.
