Epidemics & pandemics

Where can I find information about epidemics and pandemics?

Entry last updated: 26/05/22


Epidemics are infectious diseases that spread quickly in a large area or country, causing widespread illness and sometimes death. When an epidemic is out of control and spreads to many countries or regions of the world, it is called a pandemic. Cholera, Ebola and COVID-19 are some examples of epidemics that spread across the world to become pandemics.

Tips: We like sites like this because they’re reliable. You can tell because of their web address – they have either .govt or .ac, meaning they are from government or educational organisations. They’re also New Zealand sites, so relevant for us.


DigitalNZ is a search site that focuses on New Zealand history and brings together results from lots of different websites. It’s an easy way of searching online resources from New Zealand libraries, museums, universities and government sites all at once, and has lots of primary sources.

  • Use the tabs at the top of the results to limit them to images, videos, newspapers, articles and research papers.

Tips: Search words, or keywords, are the most important words in our question. Usually it’s better to leave out small words like ‘the’, ‘a’ and ‘of’ and just choose the main ones, eg epidemic. We can always change our keywords or add more if we need to.
