The 7 cases that did not have parotid swelling presented with parotid pain [5], jaw pain [3], and/or other salivary gland swelling [3].
Of 107 male cases interviewed and asked if they had “pain, swelling or inflammation of the testes,” 9 cases reported testicular swelling and 5 cases reported testicular pain without swelling. Of 131 male cases with medical chart abstractions, 2 clinicians documented orchitis.
Confirmed by cerebrospinal fluid analysis.
One case had hearing loss documented by a formal hearing test; this case was treated with oral corticosteroids and reported full resolution of hearing loss after a few days.
Cases were asked if they had “pain, swelling or infection of the breast tissue.”
Healthcare utilization totals derived from a combination of case interviews and medical records. Medical records were not available to confirm all reported visits.
