Question

Select all of the following that applies to the tradeoff between transmission and virulence that applies to many diseases.

a) The tradeoff between transmission and virulence means that diseases always evolve to become more virulent.

b) If greater virulence limits transmission, that disease will likely evolve to become less virulent than it could be.

c) While making more copies of itself can increase the likelihood of transmission occurring, too much replication of the disease can make the host so sick it won't leave the house and spread the disease.

d) A strain of a disease that replicates enough to be transmitted, but not so much that the host gets too sick to move, will be favored by natural selection over strains that either make the host too sick or do not replicate enough to be transmitted.

e) If a disease can spread without making its host sick (e.g. when the host is asymptomatic), then the tradeoff between transmission and virulence does not apply.
