Host Dezarae Haley breaks down how zoonotic viruses work — how they enter hosts, hijack cells, and spread — and explains why spillover from animals to humans happens.

The episode covers the main drivers of spillover, including deforestation, wildlife trade, factory farming, climate change, and human encroachment, and contrasts high-profile examples like COVID-19 and Nipah virus, noting key differences in transmission and impact.

Practical prevention tips and supportive approaches are shared.
