In terms of community ecology, why are pathogens often more virulent now than before? In terms of community ecology, why are pathogens often more virulent now than before? Human activities are transporting pathogens into new habitats (or communities) at an unprecedented rate. Host organisms have become more susceptible because of weakened immune systems. Medicines for treating pathogenic disease are in short supply. More new pathogens have recently evolved. Sequencing of genes in pathogenic organisms is particularly difficult.

Answer: Human activities are transporting pathogens into new habitats (or communities) at an unprecedented rate.

Explanation:

When pathogens are introduced into a new population in a community, most individuals have not develop resistance to that pathogen thus it will be more virulent.
