After surveillance teams gather wildlife samples from disease hotspots around the world, specimens are promptly frozen and transported to a lab. The following video picks up at that point in the process, starting with the extraction of the virus: 

This work is being done in 20 countries on four continents around the world as part of the PREDICT project. It's led by the UC Davis One Health Institute and funded by the US Agency for International Development (USAID). 

The PREDICT team is using consensus PCR -- a technique that is inexpensive and implementable at global scale. This allows teams to screen a large number of viruses and decide in specific cases when to push a sample through to deep sequencing (a more expensive process) for additional data.

Once the lab work is done, the results are logged, mapped and made available to governments and disease experts, leaving the world more prepared in the event of a pandemic. 

Here are the four main programmatic areas of PREDICT:
