This dataset contains the test results of the PREDICT Coronavirus Extension Project, implemented from March 2020 through September 2020 to perform additional coronavirus PCR testing on archived animal specimens. Each record describes the PCR tests conducted and the test results. Multiple tests were conducted for each individual sampled. The archived specimens tested were collected from 2014 to 2019, and originated from the PREDICT project and the archives of partners/collaborators. Additional information about some of these samples may be found in other PREDICT datasets within USAID’s Data Development Library; see Data Asset “PREDICT Emerging Pandemic Threats Project” for more information. Tests results represent current findings of the PREDICT Coronavirus Extension Project, however, additional work to further characterize and confirm some results is ongoing.
