What is a common complication of mumps infection?

Swelling of the testicles, known as orchitis, is a well-documented complication of mumps infection. The mumps virus primarily affects the salivary glands, leading to their inflammation, but it can also affect other organs, including the testes in postpubertal males. The inflammation can lead to severe discomfort and complications, such as decreased fertility in some cases.

Fever is a common symptom associated with many viral infections, including mumps, but it is not a complication specific to the disease itself. Respiratory distress and diarrhea are also potential concerns linked to various infectious diseases but do not typically relate to mumps as its complications.
