I Have A 15 Week Old Baby Who Has Been

I have a 15 week old baby who has been exposed to people that were visiting a patient suffering from mumps; one of them ,her Dad who holds her and spends time with her, has been experiencing pain when swallowing for a few days.

Is my baby at risk of getting mumps too?

If yes, how can i dictate the symptoms early and what can i do to avoid her getting infected?

Thanks
