That wasn't my question.

You only "need one" for what? To infect a person? Obviously if you don't track animal to human contacts you will miss an animal to human contact if an animal to human infection occurred. But there are thousands of infections per day. Contact tracing is unlikely to be 100% reliable over all cases. So what do you "only need one" for? To increase case load by one? I genuinely don't know what you're trying to get at.
If over all of Corona let's say 10 people got infected by animals, and you miss them. What happens then?
Should we also track rock to human infections? Maybe they could happen, and we only need to miss one...
