Well, yes, this seems logical:

An international system to monitor the health of people who work with animals would provide early warning of new diseases, a study has concluded.

Researchers from the University of California, USA, said that most significant infectious diseases affecting people came originally from animals and that a monitoring scheme could identify new diseases before they spread.

“We continue to be bombarded by animal pathogens,” they wrote in the journal Nature. “Yet there is no ongoing systematic global effort to monitor for pathogens emerging from animals to humans.”

Such a scheme would allow a database of animal pathogens to be created, which could help to identify future threats and detect outbreaks.

Actually, sufficiently obvious that I’m amazed it isn’t already being done. This however is odd:

Livestock were considered by the researchers to explain why so many more deadly diseases emanated from the New World compared with Europe, Asia and Africa.

Err, historically, it’s worked the other way around. The Old World had both more animals and more domestication of them (for example, the largest pack animal in N. America was the dog) and thus many more diseases that passed to humans. After a few millenia there was some immunity, which Americans did not have (smallpox, measles, colds even) which is what wiped most of them out. So that last line appears to be the reverse of the truth.
