Quizplus · Accepted Answer

All of the choices listed can contribute to the spread of viral diseases in a human population. Viruses can mutate, making them more infectious or resistant to existing treatments. Transmission through travel and movement increases the likelihood of introducing a virus to a new population. Handling animals that have viruses that can jump the species barrier (zoonotic viruses) can also increase the likelihood of transmission to humans. Failure to get vaccinated against a virus can lead to outbreaks and epidemics.
