Virulence is the potential of a parasite to cause harm to a host. A higher rate of transmission is linked to higher virulence. Factors that increase transmission rates include the overcrowding of hosts at high density, or mechanisms that allow the parasite to spread even when infected hosts are incapacitated. Vectors and waterborne dispersal stages are examples of the latter. . virulence. Should we expect dengue virulence evolution in response to . Dengvaxia. ® . vaccination?. April 20, 2017.
