Answer:

All these are emerging infectious diseases.

Explanation:

The emerging infectious diseases refer to the infections, which have appeared freshly within a population or those whose occurrence or geographic range is enhancing briskly or is threatening to upsurge in the coming time. The emerging infections can be a result of:  

1. Known agents, which have dispersed to novel geographic locations or new populations.  

2. Previously unknown or undetermined infectious agents.  

3. Previously known agents whose function in particular diseases was not determined previously.
