'How do emerging viruses arise? by the spread of existing viruses to new host species by mutation of existing viruses by the spread of existing viruses more widely within their host species all of the above'
Added by Kristen L.
Step 1
Emerging viruses can arise by the spread of existing viruses to new host species. This is because when a virus infects a new host, it may evolve and adapt to the new environment, potentially becoming a new emerging virus. Show more…

What requirements must be met for a new virus to emerge and spread? a) The virus must infect at least two different animals before infecting humans. b) The virus must come into contact with a new host so mutations will occur which allow the virus to bind to that host. c) A mutation must occur in the host allowing the virus to bind to the host. d) A mutation must occur in the virus allowing the virus to infect a new host, and the virus must come into contact with this host.
