If you stand beside a healthy person. Then stand beside a healthy person who sneezes by what percentage?

Question

is there more of a risk of catching an infectious disease (cold etc.)?

Answer 1

I don't quite get your question but I'll try and answer anyway.

If you stand next to someone and they sneeze then you can only catch something (a cold or something) if they have the germs in their system.

They could appear healthy in that the cold hasn't taken hold of them yet and they're not yet displaying symptoms.

But if they don't have/ getting a cold or any infectious disease- then no you can't catch anything from a healthy sneeze.
