This song is the point of view of microorganisms that cause zoonotic diseases, to explain how humans have facilitated their emergence from their natural reservoirs. The song has surely been inspired by the current Covid-19 pandemic: I composed the lyrics in March 2020. However, given that I am an epidemiologist (plant diseases), the foundation for this song has been brewing for a long time and has been inspired in particular by the work of the EcoHealth Alliance (https://www.ecohealthalliance.org/).
