because it can decompose quickly and reproduce quickly
The population is higher, so people are living closer together, making it easier to spread diseases that require close human contact to be spread.
Disease spread rapidly in slave ships due to overcrowded and unsanitary conditions. Poor ventilation, lack of clean water, and limited access to medical care contributed to the rapid transmission of infectious diseases among slaves who were already weakened by malnutrition and physical abuse.

Americans should keep the country so that humans and animals don't get diseases or spread those horrible diseases Americans should keep the country so that humans and animals don't get diseases or spread those horrible diseases
