The mumps we commonly refer to is an acute contagious disease caused by the mumps virus. It is transmitted through close contact with an infected individual or someone carrying the virus. Therefore, it is crucial to isolate individuals diagnosed with mumps in certain situations. Patients with mumps can shed the virus in their saliva from 7 days before until 9 days after the swelling of the salivary glands, making roughly a two-week period during which the infectiousness is at its peak. Therefore, patients with mumps need to be isolated for about two weeks to prevent the transmission of the virus to others.
