How did the spread of disease in the Americas contribute to the start of the transatlantic slave trade?

These diseases wiped out many of the Indigenous people who lived in the Americas. They had never been exposed to these and were very weak against them. However, Africans had already been exposed to Europeans years prior. They have built up resistance to these diseases. So, Europeans began to ship out Africans to the Americas because they could work and not fall susceptible to European diseases like the Indigenous did.
